3 Things That Will Make Your Engine Last 400,000 Miles

now you get oil leaks in your car they can come from many places it can be a stinker figuring out where they're coming from because as my father always said don't assume it's only one leak you could have lots of leaks the old way was to clean everything off the engine the transmission dry real pain in the butt then seeing where the leaves coming from well today things are a lot simpler you can ultraviolet leaked out it's made for engine oil a UV light see shining UV and yellow sunglasses so you can see where the dye's coming up in this case I can see engine oils coming from around here but when I go under the car I can see the bottom of the engine's got a lot of oil on it not the transmission but just the engine We'll pour the engine off we need it open it's on our top guess they were worried that was leaking so they put it on super tight pour it in put the top back on I'm driving around about 15-20 minutes okay now it's driven around it'll circulate all the oil die so we can figure out where the leak's coming from like I said could come from many places don't just think one is it that's why the die is best you have to worry about cleaning off the old stuff because the dye will glow where it's leaking from and you'll be able to see any oil leak so luckily these fit over my glasses so I could get the yellow kind of weird looking but let's start looking around you can often get a little oil seepage around the valve cover gasket on an engine it's got over 200 000 miles that's not where the oil is dripping to the bottom it's just seepage it doesn't show any dye coming out yet so that's just a minor thing so we'll Jack it up in there and look under the engine now we get all that and the Jacks man and as we go wander we can see it's wet around now you don't really notice much but when you put the dye on okay there it is green dots coming from up in here what's up here well that's a front main seal of the engine and when we look at the back side of the engine there's some more it's leaking from the back side of the engine too now the front side is bad enough because you got to take the front of the engine apart the timing belt off you'd have to change the front main seal while you're at it you might as well change the oil pump so you'll land the camshaft seal which is expensive enough but the rear main seal leak is between the engine and the transmission and you either have to pull the transmission off of the engine and that costs a lot of money I'm gonna try this Lube guard seal fix Lube guard makes some pretty good products I've been trying this out because at205 is kind of hard to find and this seems to be similar stuff I think it might be exactly the same is because look it looks like water right looks like water that's exactly what the at205 reseal looks like so I think this has the same stuff in it so what you do part of the engine oil oh Bob not only time hotels is work but I really think it's the same as the at205 resale because main seals power steering automatic manual transmissions and differentials and that's exactly what I use the at205 reseal that I can't get here in Rhode Island nobody sells it you got to wait a few hours of operating time you drive it around you have to do all at once you can drive it over time and basically it even warrants it says if it's still leaking like mad after two or three hours getting mechanically fixed well this is not leaking like mad it hasn't even dripped on the ground here yet it will eventually but rather than pulling the engine out or the transmission out taking all front of the engine apart if this fixes that hey you saved yourself a ton of money I realize this any car that's got over 200 000 miles on it the seals are going to be somewhat worn from the engine spinning them right let's say this works and it stops leaking all you have to do is every time you change your engine oil and filter add another bottle because when you change the oil and filter you're also getting rid of this additive which to me looks like the same polymer that at205 has so it's got the same direction so I'm assuming it's the same stuff it even looks the same right you have a problem like this that isn't specially major like this I've seen these things actually stop them when they're pouring out but with a little drip like this they had a pretty good idea that this is gonna really either slow it down or stop it entirely Dark Horse in a perfect world you would pull the engine or transmission out replace the front main seal the oil pump cam shaft seals on top of the engine but let's face it it's an old car with over 200 000 miles you're going to spend over a thousand bucks having that kind of work done if this stops it and you only got to pay 14 bucks every time you change an oil extra for pouring this stuff in what the heck especially in terms of a Toyota they make pretty good seals they generally don't crack and break apart they just get somewhat worn and since these seals are an oil seal that has a spring inside it the spring is holding the seal on so if the seal isn't all softball and pliable it'll leak but if this makes the rubber more pliable the spring holding it on will help holding in that's why this stuff works for seals not oil gaskets because a gasket like on an engine it's bolted in place right it's just sitting there and if it's worn out it's cracked and then it starts leaking oil let's say you had a side oil leak and it's a gasket not an oil seal just a gasket you can go and try to tight but sometimes they shrink and tightening and they won't leak or sometimes you tighten the leak even more if they're cracked and that breaks them entirely come pouring up no sealer is going to fix that you can't put a sealer in for example that's going to stop valve cover leaks because that's just a valve cover gasket it's not an oil seal but in this case it's the oil seals that are leaking so why do these oil seals leak unfortunately there's only two reasons one is if you buy a poorly made car and it's got poorly made seals they leak because they weren't made right and after so many hundreds or thousands or millions of rotations they just wear out and they start pouring out but in the case of Toyotas the main reason the oil seals leak is because people don't change the oil enough that's why you want to change your engine oil every 5 000 miles or soar once a year because the rlcs are made out of rubber right I mean GM tried some Teflon seals boy they didn't work they leak like a sieve and everybody replaced them with regular rubber ones later you got dirty oil what is dirt dirt is friction like sandpaper if it's dirty enough it's bad enough that that friction and dirt is wearing the metal pistons in your engine which of course takes a really long time to wear them out right they're made out of rubber and what's going to happen with rubber when it gets friction on it it will have much more wear on it than metal so even though you might think oh it's just an oil seal it only costs 22 dollars yeah but if you've got to pull the engine or transmission out to replace that seal that 22 dollars is going to go up to a thousand or more in many places it's an awful lot of work that you can avoid in the first place by just changing the oil regularly I say no it's an old vehicle I don't need to change the oil line if it leaks to burn oil I just add it just still got it changed how do you think the 17 year old motorcycle still runs like a top doesn't drip any oil look the shininess there's no oil leaking there's no oil leaking on the floor my wife would be mad after I made a nice floor right and it's 17 years old because the oil has been changed regularly it's taken care of it goes really fast because it's been taken care of and the main thing if you do nothing on a vehicle other than put air in the tires when it gets low go and change the oil every 5 000 miles or so with full synthetic oil that's a better oil lubricates better keeps cleaner and of course if you live in northern climates it flows better so instead of having a car when I was young they had straight white oil 10 wheel 20 weight all 30 weight off 40 where it was just one weight and if you had the summer 40 white oil in a winter you'd crank the edge over oh oh and it started off synthetic oils flow great and I'll start right up in the winter so there's a lot of reasons you want to do it they'll last longer and you want it to spend money fixing things it costs a fortune that would have never broken except that you didn't change the oil enough just remember this it's simple oil cheap engines expensive even changing a twenty dollar engine rear mean oil seal is expensive because you either got to pull the engine or the transmission out to do the work why you'd want to take a chance of that versus just changing the oil is beyond me strangest thing is of course it's more important to do on an older car because the new car is new and the seals are new and of course they're going to seal better right but an old car everything's old you actually need to take better care of an older car than you do a newer car so just keep changing oil every 5 000 miles cheap thing do it yourself if you don't find a place that does it for a reasonable price it doesn't rip you off but the way it is today everybody rips everybody off so even the oil change joints you go to them they'll try to sell you 50 things while you're getting your oil changed and they'll sell you some bulk oil that's in a container that they buy cheap and I know a guy who runs a discount oil thing he buys his oil filters for 99 cents a piece right hey you know what 99 oil filters you want quality ones so if you do it yourself believe me you're going to save a lot of money in the long run and you're not going to have to worry about people trying to sell you a bunch of crap that you don't actually need now the leak stop will take two three hundred miles to really do its job but we're just talking to the husband who owns this guy he tells you to keep adding a ton of oil it's not leaking a tunnel oil it's only leaking a lift this is the infamous Toyota 2.4 liter engine that burns off because the piston rings are worn all I got to do is pull out a spark plug take the cover off take out one spark plug first take the coil Off remove it and we'll check one spark plug we can see it's burning a lot the firing end is oily it's burning a lot so it's burning off you'll live with that my grandson's got one Camry same engine Burns oil he carries oil in the trunk and he adds it every time he fills it up he checks it and then adds whatever he needs to add simple to do but you're not going to rebuild an engine an old car like this it's not worth it put the spark plug back in put the coil back on bolt it in place and put the beauty cover back on it's not very beautiful anymore but it's here so we might as well stick it back on and realize you're just going to be adding oil to it a lot you live with that you don't rebuild an engine but it can still run a long time I have to solve us the stupid check engine light comes on the owner of the Chevy took it to various places they told them various stories he went to an auto parts store they sold on the wrong part so let's go through it the right way and figure out what the heck's going on here so we're gonna get out the big guns and not mess around this will tell us everything we need to know and more and here we go start setting it up now he did notice when his check engine light came on his gas mileage got worse so there's a reason to look into it there are hundreds of things it can be don't ever guess use a scan tool and in this case I'm using the top line scan tool because I'm going to find everything that's wrong with this car and find out if anybody was telling the truth or whether they were all fools we'll do an intelligent diagnosis it's just like gambling Chevy Colorado 2007. there it is we'll go to diagnosis and we'll do a whole system scan here we go it checks everything doesn't take all that long either goes through all the different systems check out the report now we're doing the smart scan it's going to find what's good and what's bad and since it's color coded obviously red is bad green is good okay so we'll start out with the PCM it's got a code P0449 evap permission evap Ben solenoid control sir now that's a code for the EVAP system something's going on with the vent solid could be a badge vent solenoid could be a wiring but that's not really going to make the vehicle run poorly at all it's just an anti-pollution thing so let's look at the other six codes here well the electronic brake control module he knew the ABS was acting up and it's got a code for the left front wheel speed sensor the right front wheel speed sensor the left front anti-lock brake system channel in release too long it's taking too long to release the right front end like brake system is taking too long to release it lost communication with the computer and lost communication with the body control module and dash integration module well we know the ABS didn't work and now we know it would probably cost a small fortune to make it work just realize the ABS isn't working correctly Drive normally I only have one car that has abs all the rest don't so to me it wouldn't be that big of a deal well now comes the big guns we're going to analyze the live data stream and try to figure out what's happening why his gas mileage went down we're looking at the air fuel ratio 14.7 to 1 is perfect and what is this 14.70 to 1. so that's working okay okay we know it's not the engine coolant temperature that's got the right temperature knew it had an EVAP problem right it's probably a bad evap vent valve because the car's idling and when the car is idling it's not supposed to vent here it says evap vent solenoid is commanding venting so it's only supposed to vent when the car is sitting it goes to the charcoal canister gets rid of the hydrocarbons and pure air theoretically at least comes out of the vent on the top but it's venting now when it's running which it should never do so either there's an electronic problem commanding it when it shouldn't or the valve itself has gone bad but that's really not going to make the thing run bad so let's keep looking now for some reason the long-term fuel trim is 7.81 so it's adding 7.8 percent fuel in the long term so for some reason the computer thinks the vehicle's running lean doesn't have enough fuel so it's adding 7.8 percent Fuel and that's enough to make it have crappy gas mileage well let's look at some more information now here's another weird thing the short-term fuel trim as it's running it's actually subtracting three percent point seven eight percent so it's actually running rich at idle but lean and high speeds let's rev it up a little see how I rev it up and now it's adding fuel now it's zero but it's adding fuel and then subtracting fuel the short-term fuel term is showing what's happening right now the long term over time so long term it thinks it's running lean and it's adding fuel but your term it's subtracting fuel this is kind of a classic sign of the fuel injectors are a bit dirty because it might sound crazy but a dirty fuel injector they're supposed to make an upside down cone perfectly shaped cone to spray atomize the fuel if let's say they're dirty you might think well they're dirty give less fuel so you know it wouldn't be running rich when it's idling but no because if it's dirty instead of spraying a nice Mist it Globs and the Globs have too much fuel so it makes it run rich because the Globs aren't a miss and it's running a little bit too rich so when I revved it up it actually went the opposite way a lot of times a dirty fuel injector will do just that well let's check out them this our data see if it misfires at all now we're going on 80 88 cycles of misfire data do you have it shows any what do we have misfire it's a five cylinder zero so it's not having any misfires but if we look closely over time we'll look at the history the top ones are live up to a certain amount this is the total history and the total history shows two on cylinder number two all the others are zero some reason cylinder number two has a history of two misfires he's on this since new he's never changed the spark plugs that is the Numero Uno thing to do a small amount of misfires I've seen them where they have hundreds this one was only two it's not much but if they're all worn over time it'll get cumulative and it can start giving you worse gas mileage especially as the Gap starts to stretch on it so I'll get all this plastic crap out of the way and press toe now we got some room we'll check out the spark plugs protect the ignition coil off and pull out a spark plug oh okay I got spark plug to look at it worn out spark plugs so you got new spark plugs and here's a warning modern spark plugs are all coated you don't have to put any anti-seize on them if you do they won't be on right so just put them in like this stick it in now you can use the torque wrench if you want you get them finger tie then put a ratchet this is on then go just a little that's perfect and I will put the ignition coil back on and we'll do the other four always change all of them don't be full I already changed just one unless you have an old junkie engine where one cylinder so worn it eats them up then you can change just one at a time never ever forget to tighten the clamp because if you don't tighten the clamps you get an air leak the mass airflow sensor measures the air coming in if this leaks you'll have unmetered air going in your car will run like crap simple thing to Chuck just make sure you get them nice and tight so let's check it out all right now people who know me well no I'm not a big GM fan but this five-cylinder inline engine is actually an excellent engine I had a customer in Houston with over 350 000 miles on his and it burned a quart of oil about every 1200 miles but not bad this particular one doesn't burn any oil at all yet so they're not extremely powerful engines but they could tow enough weight and they can last an awful long time let's take it for a road test now you can see that five cylinder engine it's in gear they're smooth idling engines it's one of the reasons they made six cylinders and then they had a few experimental fives to various companies and they all work quite well now Audi's made five cylinder engines for years that were notorious for smooth power bands there's nothing wrong with a five-cylinder engine they just never were all that popular now this truck has positive Traction in the back and it's got that five cylinder engine let's see what it does in our little track here in a second when this car gets out of the way well we're gonna have to go now it's got decent oomph to it it's a very good little pickup truck so now you know in this case it needed spark plugs people are going to try to sell you a ton of stuff people told them all kinds of insanity they said you needed oxygen sensors blah blah blah he didn't need any of that now he didn't care about the ABS three of the sensors have problems ah who's even gonna bother fixing it stops good enough check engine lights on because it's got evap leak if it runs good enough now and gets good enough gas mods he's going to leave lead along too scan tool a little bit of information there's a lot of stuff you can fix in your car now you don't need a fancy one like I have that fancy it just makes it a lot easier to cover all bases even if you didn't have a scan tool you never change the spark plugs and it is the original spark plugs on a car that's what 15 years old so what the heck change the spark plugs it's not hard we got a Toyota Highland it's running poorly and the woman who owns it wonders if the work she's been paying for has even been done so we're going to check all that the first thing we're going to check is there's a bunch of lights on some of them we don't care but as we go to the back you can hear it's not running right hear the thumping it's definitely misfiring you see the check engine light is flashing when it's flashing it means there's something relatively serious wrong so I always start with a quick look it's definitely shaking I don't have any vacuum licks or anything sometimes these hoses get knocked off but you can see they're all still there don't get the old computer out now she's had it for about eight years you can see it's got 258 000 miles on it so we'll get out the plug and stick it in the OBD plug and we'll start analyzing got some wear in it you can see she's not a smoker but the previous owner was she was given the car she does a lot of driving that's how I got all the mileage on it but here we go cylinder one misfire detected so it's cylinder number one misfire so we'll take the beauty cover off which is a dumb thing anyway in this case it's bolted on so we have to unbolt it they really went all out on these so take off the beauty cover what we're going to do is we're going to swap coil number one with another coil now of course you'll know it's a stinker because the number one cylinder is hiding under here so we got to get in there and take it out we're going to swap the number one with the front here in the front there and we'll see if the mess moves so we'll do the easy one first and take this coil off and remove it a lot of times they stick so you wiggle them hello now what we're going to do is we're going to change this coil for the one if the misfire moves from here to here we'll know that's a bad coil and we just have to replace the coil now there would have been a lot of cursing and swearing getting that out but ladies standing behind me so I stopped that and now what we're going to do is we're going to put a coil from the front and the back and the one that says it's misfiring in the front if misfire moves well no it just needs a coil I just have to put it back in because then the bad one's going to be in the front it'll be real easy to change if that's the problem here's a tip to get to the back one to get it out there's a 10 milliliter bolt you can't reach but with one of these Flex head wrenches you can reach it the front ones they're real easy to get to doesn't matter but the back one there's no room so you need one of these to get it back on got the ignition coil this is the one that we think is bad that was on number one we're going to move it over here what's going on and we'll plug the connector in that's what holds it on and now the first thing we're going to do is turn the key on turn the key on and we'll erase the code now we have to do that because it's got the start code so we'll do a race coat that's erasing the codes if we don't erase it the code will still be there it'll confuse it you can see we Chuck it the codes are gone so we'll start it up now you can see the check engine isn't on yet but we're gonna have to drive it around and hopefully it'll come back and we'll see if it's moved this far away from the number one that we move well it's getting all ready to drive around but the check engine light came on flashing on and off and misfire cylinder six pl306 number six well we moved one to six so now six is misfying so we know it's just that ignition coil not shaking anymore bolt this back on not that it serves any purpose but we're putting it on anyway don't you shave it for an old car with all this mileage on it no she wanted to check the tire so I'll get a tire gauge out we'll check them let's check the tire pressure that's 28 check this one that's the same so far they were both the same that's the same and the last one that's the same two now as I look at them they're not too old that one's not dry Roddy that one's not dry rotting this one's not dry running and maybe there's this and I got plenty of trash now she does a reasonable amount of driving for the church so she said she drives 12 to 14 000 miles a year so that also keeps everything going because you're using it all the time if you don't drive much so dry rot they'll slide they'll get out of round spots because they sit all the time but she drives us enough that there's absolutely nothing wrong with the tires a lot of people as they age don't drive much and then the tires even though they look good when you get close you'll see cracks on them they'll lose air then you got to replace them but these are still in really good shape she drives all that many miles they're not oddly worn they still have the same amount of pressure in them so you don't have to worry about that it's an older car of course the tire pressure monitoring system doesn't work anymore it costs too much money to fix that stuff but there is one more thing we could turn off you can see that was the magnets acquired light so we're going to turn it off which is easy to do yes push the odometer reset then turn the key on and you can see now it's ah she did say she's got a little oil leak so I'll check under here and we can see a little bit of seepage there which is typical on these things it isn't too bad because it hasn't even reached the ground yet what that is it's typical on these you'll often get a little bit of leakage on the front main seal of the engine you're gonna close to 300 000 miles you'll get a little seepage here and there you're not going to tear the engine apart to replace a main seal it'd be full hard he's not even really dripping on the ground but they all do that and I looked at the other side the rear main seal is leaking a tiny bit and you live with that oil is cheap to pulling an engine out to change the seal costs a fortune so that you don't worry about like I said it's not even magnet to the ground they're going to look typically like this engine does and my ultimate you put your hand there yeah so it has a little oil but I mean hey they all seep a little bit and it's going to hurt anything it may be all old it may have come in here running poorly but it's leaving running quite fine just by a little ignition coil you ever think you got a bad one you got a misfire swap them just like I did put it in fixes it we're just happy that it wasn't the one in the back in the middle because that one you got to pull all intake manifold to get to at least we were lucky enough that it wasn't that one because that is a job taking the back of the top of the engine off this case there was enough room to get to the number one and swap it out and as you can see hey it may be old but this thing I've seen it with 500 000 miles in Texas it's still going strong after all these years and it was a simple fix so if you never want to miss another one of my new car repair videos remember to ring that Bell [Music]
