2012 Buick Ecotech Blowby Issue part 2


today increase for farce repair we are going over episode two of the Buick a piston ring replacement if you did not see episode one be sure to click up in the corner I will throw a link up there so you can go to that first before you continue on here because we are continuing where we left off by a camshaft out and I’m going to continue taking the head apart to get the head being full so stay tuned and we’ll get ready to it alright so we are right back where we left off I have taken this one out and as I said I’m gonna look up how to do the timing components when I go to put it back together for now I’m just gonna take this guy and slide to the side like that and I’m gonna pull this camshaft out and I’m gonna go ahead and keep all these little rocker arm things in the same order so what I’m gonna do is I’m gonna end up putting this camshaft and that way when I bring it to the machine shop all they have to do is put it in their parts washer as an assembled head and that will make life a lot easier order it looks like these head bolts can come out so I’m gonna start loosening head folds quick I think this corner might be the only one it’s gonna be trouble one thing I should also note is there are head bolts down here so you don’t want to take these large bolts out until you make sure there’s no smaller bolts holding the head on because it take a large bowl so if they have a lot of torque pulling down on you might end up screwing up those small bolts you always gotta go for the small hole skirt and then reverse cross tore come to remove them so I’m gonna get started with that pretty soon we’ll have the cylinder head off here at imagine I might have to lift it up for this exhaust manifold though it looks like that might give me a little bit of trouble so we’ll see what happens now whenever you pull these things you always want to make sure that you check these screens for a bunch of debris as you can see this screen here is loaded with a bunch of debris that’s a sign of a future failure so you want to be sure to clean those out this one right has a bunch of debris right on that screen so be sure to clean those up before you reinstall these and and keep them in the same position even though I don’t think it actually technically matters but in light they are different color I’m not sure if there’s something different between the two of them but I believe there is so just keep that in mind keep them in the same order for good measure excited to pull those out to make sure that I don’t bust them while I’m doing the headphones because these things are insanely tight so they’re they’re very creaky that’s save at least here go ahead and just watch this one here as I bust it free definitely hear and feel it does that so I’m only going a little bit and then I you can see I’m going across torquing moving up to to trying to keep it as even as possible to reduce head warpage because if you reduce head warpage the head will need less circus machine and get it through again all right so as it turns out I definitely have to take these actuators off because the kind of interference issue with this I can’t lift the camera because it’s hitting the bottom under here where this thing has a counter sunk section so I definitely have to remove them so I’m gonna go ahead and get this one pulled out then go from there yes okay so on the exhaust do it differently than I did it this exhaust manifold here can be left on the cylinder head I did not realize that there is actually a set of nuts that are attached from the top here I thought I had to do it from the bottom like most cylinder heads there are most exhaust manifolds in me so trying to avoid that and that’s why I took it off the head at first I mean I really didn’t kill it till that much time but if you just take the three bolts up here you can take the head off with the exhaust manifold and then address the exhaust manifold over the car so it’ll be a little bit easier at least and then another recommendation for that is don’t take the o2 sensor out of a bung just take the connector off and bring those two sensor with the manifold because a lot of times you don’t stripping out though to sense are trying to remove it right that thing was heavy that gasket here ended up binding trying to pull it up and I had a hell of a time getting it out of there on top of that and this little corner here and there’s a bowl that was snaky I had it for sprite so I pried between here and a little section of the head and then I very carefully use the pry bar on the head itself because it’s getting machine but I make sure I put it Hannibal we’re here where I knew there wasn’t going to be a gasket sealer except for this spot so if there is still damage I’ll just put a dab of RTV on it look really really small dab otherwise I have to clean out all this antifreeze in the cylinders and then we can go ahead and get to the bottom half and get the Pistons out you need to convert I’ll bring you guys down here take a look but you see that weird lumpiness that’s going on on this thing the converter has actually begun to melt on this car and it’s probably from all the excess oil that has been burning so I’m gonna suggest that they could have converter but now it would probably be a little bit easier to replace it then once I get the car all back together let them know that it isn’t an issue or well be an issue in the future I’m gonna go ahead and just keep going here and I’ll see what they say I guess customers the one who just thought make the ultimate choice on this okay so as you can see I just quickly wipe this out just a little bit just enough slope of 90 degrees everywhere now before I go too far I will end up having to take and run a tube in here and siphon out the antifreeze that is in the black because I don’t want to have that sit in there when I’m trying to pull out these bolt holes and whatnot you definitely know what the bullet holes when doing a job like this otherwise you’ll end up with a hydro box from a bolt and potentially wreck the block so you definitely don’t want to glue it inside the bolt hole so with that let’s go ahead and get to the cylinder here because we have to prep the cylinder head for the machine shop it’s not ready yet because this people have a direct injection so we don’t want to send him with the injectors in the cylinder head so we have to pull those out do that quick and then we’ll head over to the machine shop and get cylinder head dropped off so as you can see a head of the cylinder head and a head of an upright position here are some rags under because there’s definitely gonna be oil leak you know I’m gonna go ahead and these bolts out of here because we don’t need to send those to the machine shop no the direct injection this is gonna be the injection rail so I’m going to go ahead these bolts out and then we will get these out another one I might have to pry quite a bit on this rail and I’m not try and do it very carefully try not to damage anything they have like a metal ring usually or a nylon ring inside here to seal them and I’ll give you guys a better look at what those look like once I get it out I’m actually pleasantly surprised how I came apart it came apart relatively easy I’m gonna give you guys a closer look at how this system works okay so obviously there is the inlet for the fuel the fuel rail the injector port or whatever the injector plugs into and then the injector itself with the wire connected to it and then on the injectors so so this one has the double hard rubber style so there’s two rings here but those two rings are what seal this thing for the cylinder head sometimes they’ll send it them along with the gasket kid so I’ll take a look and see if they’re in there but there’s a special install procedure for those when you have to put those in so if I run across that I’ll be sure to let you guys know how that goes and what you need to do to get those installed but if you look at the head here you can see these are the ports now you’ll notice their location here is way down by the bottom of the intake port and the reason for that you know the direct injection for those of you who do not know direct injection literally injects it directly into the cylinder and that’s how that works it makes it have a bit of an advantage when it comes to making the engine run a little bit better but it does make a dirtier engine because the intake ports end up with a bunch of positive crankcase ventilation deposits and I’m usually this one has a plastic intake and was actually pretty clean which is surprising considering the amount of blow-by I’m probably gonna also take and remove all these sensors here before I do that but I just figured I’d show you guys removing the fuel rail before I went ahead and ran this to the machine shop okay so I’m underneath the vehicle now and part of the game plan here is to get this gentleman the main game plan is to get this oil pan out that way push the pistons up the top in order to to do that the best plan of action that I come up with is to take and drop this side of the cradle only but unfortunately in order to do that I’m gonna have to take these brackets all the way over here loose and then I have to take the main Bowls loose and eventually I’ll be able to lower it but this exhaust is also going to be in the way there’s several things that are gonna throw a potentially a decent amount of headache for me but a hopefully hopefully I can get it just enough that it’s still lethal the oil pan over here it should about hopefully not too bad but we’ll find out so with that I’ll go ahead and get started well I was interesting I gotta pay you know but it kind of like I made one heck of a mess that is where you guys were on that stand you guys can see I have access to the rod bolts now I’m gonna turn the crank a little bit it looks like but I’ll be able to get all four of them at the same time which will be really nice and make life pretty easy we’ll go through the rest of this process but for now I hear a little cleaning to do apparently okay so you can see I got this exposed fully no I’m gonna have to get go ahead and clean up all the gasket material RTV that’s left over here especially like right here this is where the oil sump goes into so you don’t want to leave any of that there because I don’t lend up the oil pump and I mean so that’s a bad deal I got to do that but I also have to turn this motor over no the nice thing about having no cylinder and I’m here it’s very easier to turn over all I have to do is grab the critical here and there’s long chain doesn’t bind I shouldn’t be able to turn it you know very very easy so and I’m getting drift on so another thing that you might want to go for when you do that now I’m going to zip out all these radicals I do have replaced the bolts they are expressible so I will be replacing them now one thing you want to make sure of is that you do not lose track of which rod camp is for which rod so what I’ll be doing is as soon as I pull it out I will be marking the rod in the position it is and I do not a murk them with a chisel or punch because that can actually distort the rod what I do is I take either one of those carbide gaskets super scraper feels or choose and I just scratch it you only want to leave scratches you don’t want to actually hit with a hammer because he kind of damaged thing another thing you want to do is make sure you keep the same bearings with the same rods and the same crazy location because all that is so set up to the perfect area of where it’s gonna where correctly so as long as you torque everything properly you should not change any of the geometry or dimensions up in either the parts no per the book it says replace the rod bearings but unless you see an actual problem I highly recommend against replacing rod bearings only because they are already size and there weren’t good they’re gonna sit perfectly and you’re not going to have any issues if you reuse the old rod bearings all right so that’s number four I mark a four on one and then I put an arrow 20 towards the front of the boarder on the other end but usually the rule of thumb is these tanks are always the same on the same side of the track this is our crack drive design also I mentioned that in some of my videos before these bad drive designs can only be put on one way so you cannot mix and match them if you do it will be instant problems the moment you fire it up does it well have a rod Mac or well be seized up so you’ll know pretty quick now you notice the bearings are staying with the frame I’m just sliding them back in here and I’ll clean them before I do a final and so on that very good looking good all right so hopefully you guys can see that but you can see how good of shape this is in it’s actually in very very good shape well this mortar I mean you only have 57,000 miles on it looking fortunate that the Rings fail all right so the next step here is going to be to push the pistons through the cylinder board now this does not have any kind of Ridge on the cylinder board so it shouldn’t be very hard at all what I’m gonna do is I’m gonna take this pry bar and avoiding contacting the crankshaft and making sure that it don’t touch the bearing surface I’m gonna put the edge of it like kind of in the corner where the main camp pulls up where the bolt actually goes through and it should not take much pressure at all to just lightly tap it back to the handle here and it shouldn’t go right through the cylinder bore and I’ll feel a pinch than it does there Dobis nice and easy and that one is through two so nice you need to gonna take much hurry all I did was lower the card look but and this is how the pistons laid after I push them through so you can see they obviously want clean through so what we’re gonna do is we’re gonna go ahead and pull these out a part time and inspect to see if their exact condition what may have been causing the issue if anything at all I’ll be looking at attention I’ll be looking at ring gap and things like that let’s start with cylinder number one here wow that is really tight in that bore holy cow that is a really capable I suppose divorce though that’s a little bit of the scum built up at the top especially if these rings aren’t sealing very well they’re not gonna do a very good job cleaning that so the skirts aren’t even worn out on these pistons now I hold it this way so I’m not gonna turn it until I see some kind of mark that tells me the front of the engine now I’m also not turning the piston ring yet because I’m making sure that there’s you know looking at the ring gap like a ring gap here and a ring gap here and the reason I’m looking at that is to make sure that if they’re both lined up with each other because that would also cause and only open something issue so the oil ring looks like it does not have any tension hardly at all on it so I always say the oil ring is actually the source of this failure it might of been repairable with a very good engine flush is a theory and that’s all it is at this point but if you have this situation perhaps try flushing the engine first because there is a possibility that that could take care of it there’s the arrow see it that’s the front so now we have a locator to make sure that we get these installed correctly when we go to put them back in I’m gonna still clean these up but I want to go over the rest of them quick / cylinder has the skirt coating wearing off pretty pretty bad I’m gonna look at the rest of them on that side oh yeah that’s one too so the piston is thrusting is what that means I wonder if that doesn’t have something do it the premature failure it’s only those two though and this one’s fine so it’s only the back – so I’m gonna be doing a little closer inspection of the cylinder walls on those two cylinders and comparing them to the other two cylinders make sure there’s not something weird going on here that’s causing that I gotta go ahead and clean all this up and then you guys can be right back after I get everything all clean and shiny alright so we have to cut in here I have actually completed this job and I have several tips that I am gonna give you yet but you’re gonna have to wait and watch the rest of the episodes that I will cut into those episodes that I did not know until I finished the job so be sure to stay tuned for the next episodes there’s gonna be two more this is gonna be a four part series and we will get this thing done so stick with me like share subscribe be sure to hit that notification bell and don’t forget to check out my website if you want to purchase some merch to help support me the more I get the more I can put into the channel and the more I put into the channel the better the quality of the channel would be and the more videos I will be able to put out so be sure to do that check out my website I have some shirts available now the further along I go the more stuff I’ll be able to make available and the better the videos will get I invested in a 4k television so I will be slowly starting the process of getting into 4k videos for any of you 4k guys out there as soon as I get just a little bit more I will be investing in a 4k camera and then comes the computer upgrades to go with editing 4k videos because honestly 4k takes a lot of power the 1080p I can do fairly decent enough of that I’ll see you guys on the next episode
