Here the whole story
Ok , sorry but I've been asking around so much . Here's the rundown:
1996 bonneville 3800sc (series 2) - bought the engine with 100k miles on it and I replaced the lim gasket with the zzp aluminum gasket and also did water pump, replaced rear main seal and cover plate gasket, put a 99 Grand Prix oil filter adapter on with the spring and check valve correctly. Also replaced lifters which were primed (soaked over night in oil and pumped before install) And also installed new pushrods. When running the engine I get 60 psi at idle so the oil pump is ok but only the pushrods on the alternator side of the engine are getting oil squirting up and the pushrods on the ac compressor side of the engine are completely dry. I tried motor flush and then rislone and the second drive with rislone the horrible tapping sound silenced and then came right back on the next drive. Thinking I had a clogged oil passage I tried valve medic and marvel Mystery oil but the rattlly tapping is still loud and noisy (no oil to that ac comp side valve train) . So I did a 5-7 mile drive with 2quarts 40weight oil, 2 quarts ATF, and 1 quart acetone. The rattle is still as loud as ever meaning no oil to that side. First I was told I prob have the rear main seal cover plate gasket on backwards preventing oil to that lifter bay.but then I read and see by the gaskets appearance that if that happened it would only be the balance shaft that would be starved oil . Now I am getting info about a dual check valve oil filter adapter that was needed and that that could be starving the ac compr side Lifters oil. I'd rather not have to pull the engine out and take it off the tranny just to find out that the gasket for the rear main seal cover was ok to begin with. Is there such an oil filter adapter with dual check valves? Please help!!! (Oh and thanks for reading this whole thing)
