3 Worst Used Cars Only Stupid People Buy

here we got a 12 year old bmw that isn't running right no surprise there it's running like crap check engine lights on so let's scan it the scanner up to the data port and what does it say po306 cylinder number six misfire detected now a misfire on any one cylinder can be a whole bunch of things can be the ignition system the fuel system a blowing head gasket a bad valve all kinds of stuff but all we start basically we're gonna go to number six and see what's going on there they'll be in a bmw you can see the spark plug so we gotta take this plastic crap off in this case it's a five millimeter hex head we'll take these stupid things off oh it makes them look so great doesn't it and this makes it a pain to work on plain stupidity some of these designs you gotta take half of this stuff apart to access it to get it off another brilliant german design well we'll take these clips off tomorrow over here get this out of the way then we can slide the cover up and get to the spark plugs up here and the number six is hiding way back here so we'll check that first and now you can see why i think so little of bmw's modern ones look all plastic crap this is all plastic crap you gotta pull the little line off the coil and then it's theoretically just pulls out but these are stuck because they're 12 years old and they're going to be cows to get out plastic old age heat on the engine and then the stupid cover on top of it to hold the heat in even more so the plastic retains the heat and cracks even more let's hope nothing breaks when we take it off but don't be surprised if a bunch of this plastic wrap starts snapping off in your hands you'll just have to replace it then you got to pull the coils up not an easy thing to do it's all plastic and it may crack and you're just going to have to buy a new ignition coil if it does my trick is to get a big pry bar start to pry them out because they're sitting in there there's no bolt holding them in like a better made toyota where the coils are bolted on these are just placed in but that rubber and plastic hey it's been on there for 12 years so it's often really hard to get off and you'll often break stuff but here goes nothing we try some frying and praying praying and frying getting a little looser still won't come out though now it is easy to work on the front one so i got the front one out and there's a point to this if i ever do get the back number six one off without breaking it what i'm gonna do is check the spark plug see the spark plugs okay and then i'm gonna put the number two coil here on number six and number six on number two and if the misfire moves to number two then we'll know it's just an ignition clock it's as simple as that when you only have one misfire for one cylinder to finally get the spark plug ignition coil off you'll see they have weird spark plugs typical bmw crap you see they're not regular hex heads they got these granulations but fortunately if you have a 14 millimeter socket it does fit over it you do not have to go to bmw to buy a fancy socket a plain old 14 millimeter socket will work to get it off of course a granulated one works better but here's a plain old regular hex one you wiggle it it goes right on it'll hold it and take it off you don't have to buy that special tool but you gotta have a 14 millimeter thin wall deep socket and you'll never get the stupid thing out it's not a regular sized spark plug now with a ton of wiggling and prying and then wiggling to get it off because of course there's no working room in the back of the engine out comes the stupid number six ignition coil there it is now of course it could be a bad spark plug so i'm going to take that spark plug out and put a new one in just in case now even that's a jar not much working room and i had to put three different size extensions in to get it deep enough but it seems to be coming loose and yes i can turn it with my bare hands now a lot of work voila finally and as you can see here i had to have various wiggling extensions so i put it in with just a short one then when that falls in you put this on top so you can get the socket and get your ratchet to take it off but then when you pull it out it won't come out so you got to pull it out part way then take off that and then get the rest with the spark plug now it doesn't look horrendous but all the work on this i'm not taking the chance maybe it's bad electrically inside so i'm just going to replace it with a new one just be sure to replace with the same plug these are both bosch plugs now we'll tighten the new spark plug in no working room of course in this case i'm using a stubby ratchet because there's more room for tightening up quicker it still takes a while but you can see the stubby one you can turn fast then for the final part use the big one and now comes a logical part this is the number six ignition coil i'm going to put that on number two and put number two on number six then when we drive it if the code goes to number two you'll know it was the coil that caused the problem in the whole place you don't want to guess with these things they're pretty expensive on bmws so before i forget i'm going to put the number six on a number two right now and it goes they go in a lot easier than they come out they just plug in a hole and then the connector just snaps in and you lock it with the top then we got to do it in the back i can't film that there's no room but it's the same process then we use a scan tool to erase the codes as you can see called remaining zero and start it up just don't forget to put the air filter back on make sure that's all tight well here goes nothing well hopefully something [Music] now we'll take it for a spin and see what happens well that didn't take long the check engine light already come back on so let's see what the magic computer says and magically enough is now says p0302 cylinder number two misfire hooray we didn't fix it yet but now we know it's the ignition coil because we put the number six ignition coil on the number two and the misfire moved from number six to number two so we know that coil's bad we'll put a coil in it so we get the brand new coil and swap out number two again so this time we'll just move this out of the way a little unplug it out it comes and here goes the new one back in the hole plug it in make sure it's lined up right and snap it in place there we go put the stupid bolts back on ridiculous covers i don't know why they even bother and this time we should have better luck sounds a lot better already no more they're backfiring but we gotta take it for a road test anyway and as you can see now it's are you doing smooth but watch when you step on the gas it goes no more hesitation now in the past finding oil leaks was a really messy paint in the rear end job you'd find the oily area and in this case it's the whole front of the engine it's all oily here then you'd have to clean it off with degreaser an absolutely no fun job let it dry then drive the car and see where the new leaks are coming from not a fun process i'm lazy i don't want to do all that work i don't like cleaning anyways i hate cleaning stuff i'm not even going to clean it off to find this leak because thanks to the miracle of fluorescent dye i just put a little bit of this oil into the engine oil and let it run for 10-15 minutes since this is engine oil we'll go to the oil cap take it off and pour a little uv oil in you don't need much then we start her up [Music] and let it run for 10-15 minutes plus if it's a really slow leak take it on a highway get it going 60 for 10 15 minutes then bring it back and you'll be able to see that dot and to make it easier to see you put on these yellow glasses ultraviolet lights this is a multi-function light this is the ultraviolet ones here kind of blue tinted stuff now here's how it works i spilled a little bit of the dye here when i get the yellow sunglasses and put them in front of the camera here it's now a cool camera with shades now you see everything's tinted yellow and when we shine it on you can see this stuff glowing as you can see now you can see that little green glow there see you can see it glowing where the dye comes out so you look for that green then you put the yellow glasses back on your head and get the ultraviolet light and start looking around to see where the green's coming from and in this case it's not good news it's leaking from the head gaskets and the main crank seal it's throwing oil all over the place from the middle of the engine where the head gasket is and from the seal on the crankshaft now in the case of this car it's a 14 year old mercedes v8 so the beginning of the endless money pit scenario mercedes has already begun customer isn't planning on keeping the car all that long taking apart the engine rebuilding it replacing all the seals in the head gaskets she's not going to spend those thousands and thousands and thousands of dollars to fix where the leaks coming from we know where it's coming from now i'm going to put all this at-205 reseal it can rejuvenate seals it's worth the try it's not going to hurt anything it's just a polymer there's no solid particles so just pour the engine oil take the cap off in goes the whole bottle then you run the engine to circulate it [Applause] now the advantage of using this uv fluorescent dye is obvious you'd have to clean up the other stuff the wind's going to blow oil back when you're going forwards gravity's going to pull it down it can go all over the place with the die you can follow the green up to where it starts and know exactly what's leaking now granted it's not one size fits all there's ultraviolet dye for engine oil for transmission oil for power steering oil there's a special one you can put in the cooling system it's different than this one but they make it for cooling systems so you can put it in the cooling system you have a link then you make an ultraviolet dye you can stick in the gas tank because gasoline leaks can sometimes be really hard to find you can smell them but you can't see them you'll be able to see them when you put ultraviolet fluorescent dye in wherever it's leaking you're gonna see the green coming out personally i always hated looking for oil leaks because the process of cleaning them all off was a pain in the butt then trying to decide okay here are some drips but where are they coming from now you know immediately whether it's something that you want to fix something you want to live with or something that says time to say goodbye to this car no more guessing is this leaking is that leaking is it something that's serious is it something that i can live with you use an ultraviolet fluorescent dye in any of your oil systems and you'll know exactly where the leak's coming from and as my father taught me years ago when i was learning how to fix cars in a corner texaco gas station don't stop when you find the first leak there can be numerous leaks especially in something like this mercedes it's got 120 000 miles and it's 14 years old because in the past if you saw an obvious oil leak coming out it's squirting out okay you fix it and think that's it there could be a lot of other hidden leaks this is going to find all the leaks so you can make a real diagnosis of where all the arrows coming from and not keep coming back saying well we missed that one there's another one la la la because correct diagnosis of a problem is one of the most important things when it comes to fixing cars and if you see something as simple as a little fluorescent eye and a few minutes of looking around can find the problem i say thank goodness somebody invented this stuff because let's face it people are visual creatures if you can actually see a problem you're going to be able to comprehend it all that much easier and of course the entire process hunting for it instead of having to clean it all off just pouring the leak dye in and seeing where the green dye comes out that's faster by far than even just cleaning the car up alone now when this maximo was new it was a 28 000 car now it's a 2007. even the books that generally inflate value say that this thing is worth anywhere from seventeen hundred to thirty three hundred dollars today now my customer bought this thing a year ago for thirty five hundred dollars and the first thing he said to me was yeah i wish i would have bought a toyota instead to which i responded yeah but you're not going to get much of a toyota for 3 500 i mean check this car out it's a nice looking car still got a great paint job white reflects heat holds up over time the wheels are still good nice lines to it there's no bashes or anything it is a nice looking car i tell people you want to buy one buy a new one keep it a hundred thousand miles you might not have any problems at all but this baby now that it's got some mileage on it it's got 152 719 miles guess what it's showing its age it needs quite a bit of work now in this case this baby has three catalytic converters and they're going out it is typical on nissan's and i've often had people buy the cheaper aftermarket catalytic converters and they still fail the test if you have to buy three cats for this car and you buy oem factory cats that's more money than the car's worth it runs decently most of the time especially after you put some cat cleaner in the tank in order to get it legally passed in an inspection if you live in an area that has a mission's inspecting you'd have to replace those cats and man that is one expensive job and it's typical they almost always go bad on these nissan v6 engines when they get mileage like this one that's like 150 on it almost invariably they're gonna go bad now once in a while they get too clogged up and it really runs bad when you put the cleaner and it cleans it out so let's say you lived in a place like montana where they don't inspect cars for emissions you could just keep adding cleaner you know and live with that but if you live in a place where they inspect cars for missions especially california you wouldn't want to touch this car with a 10 foot pole and you might have noticed i got ac gauges hooked up because the ac system is leaking that's the reason the guy brought the car in in the first place because it's hot here in houston and he wants to see what's wrong with the ac fill it up put some dye in look for big leaks if i don't find any just tell them just keep filling the stupid thing up because as it's running you can hear the compressor rattling a little you know at some point the compressor itself is going to go out that's a lot of money on one of these no if you don't have to have ac you don't care but here in houston that's important hence they have extremely low resale value under this hole now as we look inside hey the interior's still in excellent shape that's how they sell these things they're comfortable they handle great they got a nice nissan engine and a good suspension system and as we check the back a lot of room in the back seat and a decent trunk there's some good room in here for stuff notice the jumper cables and as i said v6 engine it's very reliable this one puts out 255 horsepower not insane horsepower but back in 2007 that was still a decent amount and it's a very zippy car the problem is this age these things just tend to fall apart they look great but it's all a facade the owner says he's got a clunk on the left front let's jack it up see what's going on there find a good jack point there's one and up we go so first we'll look inside we can see it's wet in here so the strut's starting to wear and i can see and feel a ridge kind of a scalloped ridge a worn strut can do that ass can worn front end parts and when i wiggle this back and forth i can feel there's some play in the power steering rack so that means the very expensive power steering rack is worn eventually that'll need replacing again a brand new one that'll be more than the car is actually worth although that is something you can live with it's not too bad yet it's not going clunk or clunker i've had customers driving years that way they would just buy new front tires maybe every 15 000 miles because they wear out too fast and as long as they didn't clunk when you pulled on it you hit a big bump you hear a clunk up there they would just live with that do not expect perfection if you buy one of these things used with this kind of mileage on it so let's put it down take it for a spin now as we can see in the door here this is a nissan it's a japanese car but if you notice here it says manufactured by nissan motor company this one was actually put together in tennessee so it it up it starts right up most japanese cars will now you do have to say it's a pretty quiet car but if you listen you can hear the power steering groaning because that's a little worn but it still works it does still have the feel of a nice sports sedan it does still ride pretty good even though the struts are worn even though it's old it still handles decent and let's see how this thing with a hundred and fifty two thousand miles accelerates an arc get set go it's still got some decent acceleration and the transmission still works pretty good they are made for speed and even though this one's old i it's still a fun car to drive and it rides pretty good on the highway if you heard the little talking voice he's got radar hooked up many people who drive these things have radar detectors because they tend to drive fast that's why they bought the nissan that's how they sell these things in the first place they're fast they're fun to drive but as they age like this one they become endless money pits if you want perfection now if you don't mind a car that's old but still fast fun to drive and you don't mind dealing with the hassle of getting this thing inspected because it needs catalytic converters which costs the fortune the ac maybe you got to keep filling it up with refrigerant every once in a while if you don't mind a car like that and you can pick up one like this hey look they go for fifteen hundred to thirty two hundred dollars they don't cost that much money but if you're one of those people who just want a car you can just buy and drive and not mess with this is not the car for you because as beautiful as it looks for a 14 year old car looks can be deceiving and in this case it's hiding a lot of problems so if you never want to miss another one of my new car repair videos remember to ring that bell you
