99 oil pump ????

[jymkym1]

i have a 99 cav. 2.2, i have a knock coming from somewhere, when you start the car i hear a knock and when it idles there is a knock, after the car warms up the oil light comes on when in idle or when i take my foot off the gas while driving, could these problems be caused from the oil pump, how hard is it to replace???? thnx

Is it a knock or a noisy valve train?

Sounds like some symptoms of a bad oil pump tho. The hardest part is pulling the oil pan off and re-sealing it. The car has to sit oil free for 2 days while the sealant cures.

Its a knock only at idle speed. Would the oil pump make noise like this if it is going bad

Ours died out of no where. No abnormal noise just an oil light. The 2200 is notorious for having a noisy valve or 2 which might be fixable by re-torquing down the rockers. But an oil light usually isn't a good sign.


But anyways, we Kissed that valve train goodbye. Ended up draining 8 quarts of oil out of the motor tho when we dropped the pain and realize how much shit was bad. But now we're running an oil pressure gauge, a melling HV pump, and the motor is fully built with forged rods and pistons.
