On my L67, it's leaking pretty bad...about a quart or even a little more a week. I took off the pan, resealed it and the TC with all new gaskets, and did the rtv thing to seal it against submarine style adventures...still leaked. Last night I redid the rear VC, and it didn't help; although it was a shot in the dark anyway (and I found a bad wire going to injector #3). The leak leaves the bellows for the rack wet, as well as the subframe below it, and the CV joint. I can't see anywhere where it could possibly be coming from...and am dreading the possibility of having to tear the TC off for the 3rd time.
Oil level doesn't seem to affect it, so it's probably pressure related somehow. The oil pump extension was sealed with a stock gasket, and permanent permtex sealer. At cold start-up I get some clacking from the lifters not pumping up for about 2-3 seconds. I was thinking a possible head gasket problem, but I don't see that making sense with the oil pressure indicators. Car has about 150-160K on the clock right now...almost ready to just shitcan this motor...it would probably be cheaper to just swap in a new long block if I keep having to wrench on this thing.
Bear in mind this this has been raced...a lot. I ran 16+ pounds of boost and 22-24 degrees of timing for many years. I haven't done a compression test, but I got roughly the same leakage from all cylinders recently when I pumped up the motor to hold the valves while changing the valve seals. The motor is definately tired, but is fine for a DD. I just want to get this leak located.
Any ideas would be appreciated.
