LQ1 common oil leak areas
-
Honestly surprised you dont know as much as your into these cars. Thats the infamous oil pump drive shaft that in order to change the oring seal on the LQ1 requires the head to be pulled to remove. It loves to leak oil. If its leaking you might be able to lift it slightly and pick the old seal out. Then as you rotate the shaft squeeze some RTV under the lip all the way around. Looks like that was done before at some point. IIRC one member ground the head down to get the shaft out without removing the head.

Ah, I see now! You were letting me figure it out on my own, you knew I would get it. Thanks 55!

So glad you chimed in! I always appreciate your input as I'm treading new territory here. So this little O-ring gasket needs to go under this plug or whatever it's called. Where someone has added silicone to the base of it? I'm still a little hazy about where it needs to go. Is there a specific procedure in our LQ1 manual? Or does that require a cylinder head removal? Under this bolt and hold down tab? If that's the case, could I just stretch the gasket over the top and down under the rim? Probably would break though. Crap, I'm not paying attention AT ALL! This gasket isn't even for that! It's for the throttle body passage like you said. So where's that at? I'm not getting the terminology. Pics would help out alot please.
-
The O ring that was supplied in the intake gasket kit will the O ring for the throttle body passage in the intake manifold. Gm really dropped the ball when it comes the cylinder head casting, one thinks that after the head was put into place they realized that one cannot remove the distributor drive at all. From that pic of your Greg, I do not see a terrible mess there, perhaps clean that area up before attempting to dislodge the O ring.

Hmm, I need to take that bolt out and look at that area. This is the distributor shaft/plug area yes? If you look, there is a greyish silicone bead around it. I've heard that you can fix this area without taking off the head but this is new territory for me. If this isn't the right O-ring, then I might have to reseal it with RTV. I'm not sure if it's even leaking here but just trying to be pro-active while replacing the intake gaskets. I might try your method as well once I get into it. I just don't want any oil leaks obviously. I ordered a new gasket for the Oil Distribution Cover from GMPartsGiant. Might as well do that while I'm in there too. I need two of them as well. One for this car and one for my STE. I just wasn't sure (and still not 100% sure) where this O-ring goes that came with my intake gasket kit. It's a Fel-Pro and included the O-ring, intake gaskets, and plenum gasket. Maybe I just need to look at the packaging, LOL. Hell, it might even say it right on the box!

Well, there is an o-ring that goes from the plenum to intake under the TB. There is also an O ring that goes on the shaft on the distributor plug. I'm not exactly sure which one you are holding in the picture. Replacing the O ring on the distributor plug shaft (where the oil leaks), the proper way, requires head removal. Some people have had luck replacing the O ring by cutting the old one off, and fitting it over the distributor plug, I did not have luck doing that. I left the O ring in place, got a distributor seal (they are all the same size from era of GM vehicles), put RTV on both sides and put it under the distributor plug. That has worked so far, though it has only been a few months. Other people have had luck doing that too. Yes, the big, rectangle, aluminum cover is the oil distribution cover. I purchased a Fel-pro set off of RA (MS95822) and it came with the oil distribution cover gasket (even though it isn't included in the picture). They were under 5 bucks, so I bought two of them.

Ok, so I need to pull this bolt/part and reseal it with silicone or RTV. The O-ring it sounds from looking at your old thread and 55trucker's is for the plenum to intake area under the throttle body? I found a new gasket for the Oil Distribution Cover that you are referring too, that big square aluminum cover. Am I correct? And thank you so much for replying back. I'm currently putting new gaskets in my LQ1 and some other preventative maintenance items.
-
There are two common oil leaks in that general area, one is the distributor plug seal/gasket (what you are looking at) and the other is the oil distribution cover. The rectangle to the passenger side of the oil distributor plug. It is the rectangle cover that has that "Z" shaped part on the top. You can see the cover in the top picture, lower left. The oil distribution cover gasket can be ordered from one of the GM part places, but it also comes in a set that I got off of RockAuto closeout stuff. Much cheaper the RA way.

Best way to clean out gas tank.

I've been talking to NCTyphoonKid and I think I'm just going to flush it with clean fresh gas. The tank is beautiful inside as I don't see any rust thru the pump opening. Hey, since your available here right now, I've been looking thru some threads. Do you know what this is? It has silicone around it and was wondering if I need to do any preventative maintenance on it. I don't want oil leaks. I'm replacing the intake gaskets right now.

Ah, so this is the O ring for the plenum to intake area that was in my gasket kit. Thanks 55!

Glad to have found this thread. I'm in the process of replacing the intake gaskets on my LQ1. Is this the O-ring gasket that you guys are referring too? If so, does this go under the Oil Distribution Cover? I'm also wondering about oil coming from this area in the 1st pic. There is silicone around the base of it and looks like a failure point.
-
I might have to do this to but not on a W body. Would a about a gallon of seafoam sloshed around in there take care of everything? Looks like its been seal from the pump but is there alot of rust in it?

I want to reuse my original gas tank. What's the best method to clean it out?

I just wanted to second this. Earlier in this thread I said my keyless entry module was acting erratically in programming mode. I resoldered all the solder joints on both boards in the module and now it works great, both in my vehicle and on my test bench. The only annoying part is the conformal coating. It makes the iron want to slip off the solder joints. But you can still resolder through it without going through the trouble of trying to remove the coating. Just have to be careful as you're holding the iron. If the module is acting up I would definitely recommend trying this. Add a little bit of new fresh solder to each joint as you do it.
-
Pulled the power lock fuse out, and all the interior light went out, put the fuse back in, and the locks started working.. WTF? Went and ground the wire in the trunk, and nothing... Well I guess I wont be fixing that.. But I do have power locks!
-
The solder points on the box aren't small or intricate or anything, you could definitely do it yourself with a low cost iron. Good learning project.
-
Awesome I appreciate it. Now to find someone to fix it cause I can’t solder to save my life.
-
If the locks work, it's not the fuse. If it won't go into programming mode when you ground the lead in the trunk, the box itself is screwed and needs to be resoldered.
-
Where is the fuse located because my power looks work on my 92 GTP but can’t get it to go into programming mode and it has the correct RPO code.
-
I like using some wood blocks cut from a 2x4 between the body and jack just to spread the weight out and not scratch the underside.
-
I saw one on Ebay a few years ago for IIRC $200 but I havent looked recently.
-
Yeah, if there is a lead hanging back by the antenna or somewhere in that general area, the car should have RKE. Non-working locks could be something as basic as a fuse, so I'd just start there.
-
Sorry for digging up a old topic.. Am I understanding correctly that if the grounding terminal is in the trunk, than the car has RKE? Also, my power locks dont seem to be working at all, is there a place I should start on this. I might have owned a W previously, but that was a long time ago....

Tires on, rear brakes are new and operational, including parking brake. Just need to do the windshield and AC now, and she is done! Took the Corsica out to get some gas last night, need to dilute down the 5 year old ethanol gas thats in it, to make it reliably driveable. My grandfather had a locking gas cap on it, no idea why (it was always garage kept), and since it had not been operated in 5 years, it was a bit frozen! Need to order the heater core, and get it to work to recharge the AC. Tires come next week. Found an incredible deal on some Michelin Defender T+H, new, for 35 a piece. Normally they are 116 a piece. Love my Michelins...
