I Can't Believe This Caused Our Porsche 911 Engine To Fail!

foreign welcome to the shop I'm Jared and this is the questionable garage and this is my very broken m96 Porsche engine that came out of our all-wheel drive very broken Porsche I was able to turn a broken Forerunner into a rusted Jeep into a broken Porsche and we may be uh we may be over extended a little bit I've spent my entire budget buying the car and I the engine's very broken uh your timing chain should not should not do that I don't know much about these engines I know a 2JZ inside and out and I figured I should find someone who knows this engine like I know the 2JZ and there just so happens in Cleveland Georgia my friend Jonathan how's it going he's built a lot of these engines over many many years so I say you're like the 2JZ m96 very to me I've probably done nearing 300 2js of all kinds of power levels you're pretty close when we were talking I've done I've done a whole lot of them I've uh done a lot of m96 m97s now most viewers probably know what these are known for it's the very first water cooled Porsche engine Enthusiast hated it it's still the greatest sports car ever made but what are like the known first things that are going to fail on this engine the IMs bearing cylinders uh that's about it IMS bearings and cylinders the good news is they're both very cheap fixes right yeah no no it's got to come to this point so the IMs bearing that's intermediate shaft and the way these work is you have your timing set here and a timing set here front and back I don't know why they did that I guess they wanted a really expensive shaft in the middle to connect everything yeah make it all made all fit yeah so then the IMs you run into oiling problems right and that and the bearing type wasn't very good so those would explode yeah the bearing is a sealed bearing so what happens is uh people don't change their oil and then it makes that seal swell down because that old cooked oil makes it get hard right and uh the first time they drive it after it's been sitting after a long winter it expands that seal back out and all it has is old oil that washed out all that grease that was in there yep so then they uh explode so when we're talking sealed bearing hopefully Duane will pop up a picture you have bearings with exposed cages that get fresh oil and are able to be lubricated well a sealed bearing you have hard seals that press in and it's basically meant to be lifetime groups and what we have learned in the real world vehicle's lifetime is not a manufacturer's lifetime ever no warranty warranty is the lifetime of a part pretty much and then the cylinder walls we were talking the previous episode this engine is very flat and when the cylinder walls get damaged and scored how what what is causing all of that to happen to where you almost have to throw away your centers well the I'm pretty sure the Pistons expand faster than the cylinders do in extreme cold climates and stuff so anything above the Mason-Dixon Line usually has cylinder problems it's a ticking Time Bomb until you fix it right the first time so now how stupid was I for starting this engine very very stupid I would never started never start one of these motors that have a timing problem that you know it's not a problem listen someone else said about even running it like it was done for like yeah I don't think I did this because the very first time have you ever seen a chain supposed to be connected yeah yeah yeah this this is supposed to Loop together it it made a horrendous squirrel like instantly so I don't think I caused it you're lucky that didn't snap a snap a uh cam with that uh scavenge pump so that's enough kind of introduction to the engine the problems Jonathan we need to take this apart to see exactly how how ruined this is how much can be salvaged and uh then I can get a cost estimate of rebuilding this thing [Music] all right so are these buckets gonna try to escape or are they going to stay pretty smooth uh you want to pull the uh you want to pull those the tensioner on your side right here there's this you take it off take this tensioner out uh you want to do that before you pull these uh chains and pull the caps [Laughter] [Music] yeah that's a that's a normal you're gonna have to buy those anyways what yeah I actually have some probably I might throw them your way [Music] thank you [Music] I like to try to break them all Loose by hand that's just because you have less likely to uh strip out yeah and you want to get a good Allen head if you got a perfect brand new one that fits them tight because these things are prone to do exactly what this one did over here [Music] okay [Music] foreign there we go ready for you old dentist tools go yep when you go to the dentist you say hey hey Doc don't throw this away I just buy the couple dollar ones from even though they sanitize them I just don't know about the whole thing being something I'm getting my money's worth at the dentist [Music] compliment them on some things and just go what were you thinking on others yeah engineers not just engineers German Engineers or more like uh accountants I don't know I feel like that worse Porsche might be one of the few companies that don't go accountants first I've taken apart two five boxers that have near Billet parts and then a year or two later they go to like a different casting style and you can tell it's cheaper it just feels cheaper yeah so it starts so unlike everyone else who you don't want to buy early model year buy early model your Porsche if I had a two five boxer and it screamed the tires up a mountain you were always in it that was the best part it was the most fun it's like driving a Miata but faster you hear that Miata guys the hairdresser I don't know any Miata person that actually is going to be like Miatas it's got lots of horsepower it's fast I've had some Miatas chase me up a mountain before so I can't say too much but [Music] these are your chain rail guides pims I remember reading about those when I thought it was just going to be chain guides and go yeah that's a never joke's on me your chain-year-old guides look okay you could reuse this that one well could if we're being real though I've done some uh I've done some Super Button builds some get this thing to the track soon cars okay too good cleaning good as good as possible good as good as possible all right not not good enough we want to make it if if it gets built we've done all right we want to do it right which to me is looking more like the ls huh no never no what if it's a 700 horsepower supercharger yeah the problem is it's still going to sound like an LS you cannot Escape that you really can't you can do cool stuff with like 180 degree headers and you know there's stuff to make them sound not lse but you can't in a Porsche you got two inches of exhaust you just make it so quiet you can't hear it and then that way nobody knows the different I don't know hasn't has any on a normal Drive sure they had you had to a rear axle Graziano's I've not seen an all-wheel drive I don't know well because the all-wheel drive cars are worth not LS swapping [Applause] [Music] there we go people will notice in the video that I told you to take them out by hand and then we use the impact so when I was at the dealer every Apprentice I had anytime we did any work their first time doing the job they did it by the book yeah yeah they would argue it'd be like hey why is so and so you know doing it this way it's obviously so much faster and I'm like it is faster but I don't want you to learn the shortcut first you need to know what you're doing and understand why you're doing it you should never learn the short if you don't understand what you're shortcut wide is doing it a particular way work because if all you ever do is keep teaching shortcuts you end up with parts Changers people who can't diagnose why something went wrong foreign [Music] I take it these are torqued to yield bolts which ones huh which one the cylinder heads yes could generally tell when you're you know hemorrhaging a little bit and your eyes start to soil three turn purple just take your lifter tree ah put it back there and then that way you can put all your lifters back in here and then you know where they came out of [Applause] [Music] oh you hang on the O-rings just kind of as a Force One blender just so that way you know you never throw away a part until you've gotten the one in the motor replacing it that way you know you never forget anything especially if you've never your first time for something yeah yeah it's like a 2J I can just throw everything in one box know exactly where it goes oh I've put my fair share of box specials together thank you people who do that to me everybody's had that first time you get a box special of something you don't know I don't think that guy's probably reusable what do you think [Applause] no the fact that we got two nice track lines formed there from the track lines see the the horizontal cracks too yeah horizontal crack horizontal crack what are the possibility they did it rear the rear got new guides or knowing the shot this went through probably not the core that they had gotten had a perfect looking guide but this doesn't have a single edge line but that's the side that this happened to you so that's it could have been all that in here that's that's definitely a whales how I sees it probably that's what I was it's hard to always justify just spending more and more but yeah on certain critical things there's times that it really is just there's no reason to fix something unless it ain't broke right I get it and guides are not cheap well one thing we also noticed is yes this had an upgraded IMS but it's a very very early upgrade IMS and since then like they have more of what they call Lifetime stuff it's just the timing of when this broke and got built yeah you never knew wasn't an option yet you had to pull the torch bit for that what's the what uh the extenders over here people will be able to pull the head you'll have to throw that off too these motors are also known as an internal dry sump oh internal dry sump yeah because it's sectioned off because of the uh the tray that's on the actual uh crank scraper basically for the carrier so they're they're kind of sort of like an LS7 a moist sump yeah like they call them dry sumps but they're you know this was pretty sectioned off there's nothing okay it's got a v- valley in it that everything dumps into and but it technically is still a sump I mean it's still a [Applause] man oh man I got one bolt that's gonna hate me I think don't do that let go hey those valves are totally fine look at that that's definitely getting new valves and you're gonna want to check it to make sure the head's not cracked listen I think that's what they're supposed to look like it's that variable compression option it goes alongside with that variable timing option in my not expert opinion I'm not seeing anything that makes me go oh no well you got witness marks on your Pistons well yeah and I'm referring to that these rods are uh you breathe on them wrong there's like a tiny there's a witness Mark right there oh yeah yeah but that's your cylinders look okay so far but we need to rotate that's small that ain't nothing yeah that's good so that might be the only good news so far hello we'll take what we can get listen if we escape so in theory that side was in time right currently it is looking like two valves head work well no I'm gonna shut up because we haven't even opened that yeah don't don't say good things until although really a best case scenario overhaul and this is still eight thousand dollars of cylinder heads yeah and I have precisely like a thirty you're good for McDonald's for lunch right like that's what I'm paying you right McDonald's McDonald's is good with me actually I'm gonna go even cheaper than going and buying you fresh McDonald's I got some factor in the fridge some some Ramen no no it's better in ramen it's better in McDonald's the pre-made meals I love those things I think there's a Tuscan Chicken in there and I think we got a jalapeno chicken because normally I don't stop and go anywhere and instead I get really good food but I can cook hmm right here right there it should be part of your blog no it's like machine surface right there yeah that can't be scary oh wait no right here is it oh yeah okay that's also sand cast a machine surface you're lucky look at you oh there you go with my one dirty fingernail a little higher we'll do a little higher oh there we go yeah you find scary metal if you're like no you know I want to terrify him with my assessment first and then we'll find the right thing well okay we have gotten a lot of progress done uh Jonathan said I've only slowed them down a little bit we're fairly certain we have found and kind of established the cause of what caused all the failure and it goes to show you need to clean these engines right that's that's kind of what you're thinking the culprit well we'll only know when we get it completely apart because you don't know what the IMs looks like now but true it could be a fresh failure but initial Impressions and it came apart were not instantly having to throw this engine away right our cylinder walls or yeah see your scavenge pump broke yeah oh yeah the cause of failure so if you remember when I first took this thing apart this pump was broken we found that piece of aluminum but the actual gear is broken this is a small piece that we're believing came from the IMs bearing it was the carrier that locates all the rollers and the balls it got carried up by the chain got into here and you can actually see the impression of it in these different areas so and then that's the spot right there it's a perfect match stop that thing cold and basically simultaneously snapped our chain and snapped that drive at the drive going on other positive scenarios now we've not fully turned the engine over yet these cylinder walls they're they're really showing almost no scoring at all your cylinder head visually looks pretty good my cylinder head has a variable compression valves if you notice our exhaust valves are not closed they uh there you go guys the full piece oh yeah it took a little while to get but there it is yeah that's how it looks totally kind of when it's uh not broken yeah completed so we got the thing standing upright you notice something kind of weird on the IMs but nothing real definitive possibly a clip came undone it's one of those things this had some tattletail stickers for overheating on it and a couple other things that kind of indicate that it maybe came from one place but not necessarily the work to to match it and C4s are known for running warmer because they have more drivetrain it's got the windage the Ln wind windage tree oh here we go yeah see that's really thin and that is clear baggy material it looks like fod fod foreign object yep is definitely fawed the rest of the screen looks pretty good more of that baggy material or is it just twist if you have a cam lot basically so twist it [Applause] sometimes you can see if there's any corn objects because what that is is a it's a defoamer so the oil comes in it swirls in this and then comes out the bottom so that way these these uh these engines move so much oil yeah just as they're punching around and yeah and nothing is worse than frothy oil yep the next step in splitting our case is we have all the perimeter bolts and then I think there's a couple like pass through like really deep bolts right that you need a really long socket to no I would say all these perimeter bolts then we'll lay it down really that side all these tens are what holds it together yep all those tins are all that holds it together because the head bolts go all the way to the camera to the middle so you're a head bolts until it gets the main bolts that hold the whole motor basically the head bolt yeah that makes sense yeah it keeps everything aligned with that with dowels just that's the same as the heads oh what a mess take apart an m96 on a table they said it'll be fun they said hey do you got a engine stands we don't need no engine stands we got mops we've given up giving up on gloves I've learned many times Go Gentle sometimes things take a little Force but yeah it should never be as hard as you're applying and like if it's a lot of force there you go stop and just do another perimeter check yep because you can cause oh I'm with you something's binding over here it's it's just that there's an owl okay so because it looks like it's free everywhere but the Pistons are holding it that just a little bit [Applause] now it'll literally probably wiggle right off there it goes all right you grab one corner of this side and it will just pull directly up all right you got it yep I got it I'm just gonna set it down hold on I'm just spinning it around sitting on its face the Rings are like a little sticky and the Pistons just from some oil but they're still pretty springy and it's a 90 000 mile engine so no wonder it fails so it rides on a bushing in the front this is the IMs shaft yep and it's just a bushing basically on the front half your rear half drives your 1-3 bank and your front half drives your four six bang all right so it's next so now we can take the rods off of this one this one and this one oh it's gonna make it just that little bit easier they stay in the cylinders as we're pulling that carrier out [Applause] those are torqued to 45 foot-pounds oh they're cracked rods yep they are crack rods so what I'm referencing you can see how that surface looks broken they literally kind of machine them and Forge them with a minor scoring Mark and then they break them and that actually creates a better ceiling mating surface as weird as that sounds the erratic area has more surface area oh at least it's light yeah no it's not now we can set it all right across put it up and you can pull those rods off the other side go ahead and put the Rod caps back on because our bearings look great all right so our initial look at the IMs is it doesn't appear it doesn't look perfect but it does not appear to be what broke nope so that means it's a fully rebuildable motor well and 90 likelihood that was old material yeah but after 40 000 miles finally was like all right get into this IMS has had the issue it's had though I would pull it out and replace it completely with the solution piston skirt looks good yeah this is a a fully rebuildable motor oh you know what that's a lot better news so why are the piston rings why do they have a stopper in it so that's so that the Piston doesn't have since these are high compression Motors and since they run a gap of I think fifteen thousand um it's so that this ring and this ring can't spin they don't get aligned together through combustion okay and it also keeps a wear the exact same through that cylinder let's take a good look at our IMS and then I'm going to start cleaning up this mess you are going to start putting together a price oh I don't want to tell you all right things are cleaned up uh Jonathan has put together a number but before we get to that let's show you some of the engine case parts that we've got all taken apart and we finally found what some of our metal was from like literally just figured it out as we were trying to go through it all so again our cylinders here our cylinder halves they look phenomenal it's a good thing because this is one of the quick things that more or less will total mechanically total a rebuild like these are rebuildable good cores all of our bearings like our bearing sections here on the rods they have almost all brand new material in them like a bearing has its initial coating and then it has what it lives on and sometimes you never get through that initial coding Pistons look good we have that one pair of valves fully bent there might be more damage there but we still do not know where that came from it's a hardened tool steel we're both fairly confident it was probably a bearing cage from the old IMS that's like the only thing we can really put together it makes no other sense we found a bunch of other material and what we just realized that was when this locked up and it broke the timing chain those are actually the spacers on the link so that's just part of the failure not the cause of the failure right this broke this this broke that minute yeah so the timing chain brought up that chunk of metal that locked up our scavenge pump stopped dead cold broke the chain yep our valves decided to introduce themselves to the Piston the Piston as I do cars calls it there was malice in the combustion Palace I like that phrase it's a good one so it's not as bad as it could have been yeah definitely fixable what is needs fixable what what are we talking dollar amounts and parts new scavenge pumps new timing Chains new gasket kit new head gaskets new IMS because don't quite trust the one that's in there and if it's a part anytime put a new water pump put a new AOS put a new air oil separator a new uh heat exchanger for the oil yeah new uh chain rail guides oh come on those were fine it's only missing most the plastic nope go ahead and do that and then the uh the heads have to go to The Heading shop the heads need to go to the Machine Shop okay sure so and the the chain rail guide on the heads one of them needs to be replaced yeah so you're looking what's that dollar those are parts that what's the price probably about eight grand or so hey the the biggest problem is I my entire budget's currently in the car yeah and that's not labor like the only labor baked into that is the Machine Shop which therein lies one problem there there's again the three scenarios on this car we've rebuilt this it's eight grand we do an LS swap which I'm not the biggest fan of we were talking I don't know that I've ever seen an all-wheel drive LS Swap and that's because this car currently you were saying if it's running well especially with a fully documented rebuild um it's done right it's worth more it's like a 40 to 45 000 car potentially which which is still a tremendous profit but I just the cars worth too much to put in LSN you might as well just fix the motor that's in it because it's it is what it is it's gonna cost like the same like eight grand and fixing this a proper LS swap you're spending eight grand really quickly anyway so German um but I don't have the budget for it so the the other option is the part out I have a guy that buys me out but I'm not I'm I'm personally not a biggest fan of that because we don't make any money and move anything forward I'm not sure what we're doing but I do want to address something real quick regardless we checked with machine shop and it's legitimately potentially two months on a set of cylinder heads so this isn't a forgotten project it's literally one that we have to set aside because the moment I sent these cylinder heads out we have to wait like there there's people who can get it done quicker these are a specialty head I've always felt like unless you have a long established relationship if you walk into a machine shop and they get to you that day there might be a reason that they're not busy because there is not a thing in the world right now that is not a backed up machine shop yeah they're just they they don't exist so we had three really quick episodes on the Porsche unfortunately no matter what direction we go there's there's a way on parts on time on on anything so we're not giving up on the project it's just we have to wait so I'm going to post a couple behind the scene updates as we're moving along on this project for the members just so that way there's a little extra perk if you guys wanted to sign up Jonathan thank you very much for Lending expertise that's what I'm here for I I guess I'm gonna go donate some plasma or something so that way I can start you don't need both your kidneys so I appreciate you guys as always hanging out with us here in the shop as we make very questionable choices and this was one where they didn't quite get all the metal out apparently uh who knows it took 40 000 miles but it blew it up so I'm join us next time as we continue to make questionable choices uh I've already said that I'm just I'm kind of shelf a little sticker shocked because normally I can fix things for like some bailing twine and twenty dollars so no bailing twine here we'll see you next time hey remember when you kind of were like hey if you've got any opportunities you wanted to kind of help out a little bit get in and maybe make a little bit of money I've got an idea if you want to um it's kind of a sure thing we're going to do pretty good on it yeah no it's it's not a small number it will probably need about 10 000 or so coming in yeah come on but listen I'm not asking you to judge me on the winners judge me on my losers because they're so few like this this is a sure thing we're we're gonna do good you're in all right I'll put you down on it we'll get stuff coming for it all right foreign [Music]
