Front Oil Pump Cover

[91Bird305]

Is it common (if the downpipe is semi close to this area) for these to warp and cause oil leaks? Because mine runs down from the front of my motor (pass side under the A-arm) and we replaced the gasket and it's still leaking. Should I just replace the whole thing? It might be warped enough where I can't see it, but enough to leak oil (about a cup if left running long enough). Only leaks when the car runs.

Take a big file to it & make it flat.

No, it is not common to have a leak on the cover at the pump/filter housing.

Some possibilities are the housing itself is cracked, gasket for filter housing is bad, or not installed properly.

Best to raise the car on a lift with the engine running to determine EXACTALLY where or what is leaking.

The cover shown is made off-shore, and they are well known to have issues of fitment.

On the area we just put the gasket? We are 100% sure this is where it's coming from. I don't see any cracks. Just making sure there isn't another area on that cover that could leak besides that gasket or the back of it that goes to the motor.

mine has done the same thing in the same area since I put it on....I'm gonna rip it off, have it machined flat, and try again. If that doesn't fix it.....stocker is going back on.

Just get one from Earl Brown, spendy, all work and mods made to it and all GM , it is all put together and ready to install just waiting for the prime to be put to it, JMHO.

I know but 400 bucks? I know some time went into them but ouch.

Earl isn't making a profit from them. He bought all he could get when GM discontinued them. He paid about $300 each and he's doing the mods for another $100. If you ask he'll even throw one of his pornos in with it, or so he said at one time. He really knows his stuff on oil mods and it's one of the best things you can do.

you guys using dbl. roller chains on your timing chains? and if doing so
are you also using the forward cam roller tensioner that goes from the nose
of the cam to the inside of the timing cover, yes or no on this would be
help indeed, thanks.

Nick allow me to chime in here. I'm sure you're aware of the problems involving Chinese aftermarket covers but some of the less experienced may not. The main oil channel starts out at about 1/2 in. & necks down to 1/4 or smaller & is blocked with casting flash. A long sharp drill bit should be used to clean that out. There are machining problems on the face where the oil filter adapter bolts to causing leaks. A flat wet stone can be used to smooth that surface as well as the adapter,Care must be taken not to disturb the oil pump gears to cover clearances. Using a file is too rough & I wouldn't recommend that. I have also run into the other oil cross channels that was completely blocked during the casting process causing no oil pressure. Thats why priming the oil pump & making sure there is pressure is important.I have an old cam sensor that was modified for that purpose.There is also a plug near the cam sensor hole that could fall into the timing gears because it is a straight thread & should be discarded & tapped to 1/8 pipe or at least locktite it. The main point is the covers are of poor quality but unfortunately sometimes the only available option. If possible compare a stock cover side by side with the other & make sure everything is as it should be. In addition I have always favored the yellow relief spring as sufficient if all the engine bearing clearances are correct. low oil pressure is an indication of problems a higher pressure spring cannot fix. I also like to take a fine small file & deburr the pump gears & make sure they rotate smoothly in the pump cavity & make sure everything is clean before assembly. Regards Lou

Oh I know. I'm not treating it as a rip off. It's just a lot of money for me right now. Pay to play though I suppose.

For about the cost of an off-shore cover, we sell the TA cover which they precision machine to even closer tolerances than stock. Very little mods, if any, needed for this quality piece.

Lou's info is very good, but most of the work mentioned is not needed with our cover. His comments on assembly and checking are applicable though.

The ones we have installed replacing a modded stock cover have produced 5-10 psi more oil pressure.

I wasn't saying you were. It's expensive I know but if you want it done right it costs some bucks to do it.

LOL Sorry about that Aj.:biggrin: Earl really does make pornos on the side though.

Thanks Nick I wasn't aware that there was anything else was available. Since there is it's money well spent as opposed to damaging an engine plus the advantage of tech support. Lou
