I have a 97 LT1 with 80K on it. I bought it used and the person before me put the LT4 hot cam in it. Just recently It dropped a valve so i pulled the heads and ported them and also changed to a bigger cam. After it was put back together it ran fine for about 500 miles with great oil pressure. Then I noticed at idle the oil pressure kept getting lower and lower until it only held a few PSI. I confiremed this with a mechanical guage. My question is when i changed the cam i used the stock lifters. I noticed when i pulled the valve covers all the rockers had oil coming out except for one, It had oil gushing out of it. Has anyone had a lifter go bad and cause this? When i first put the motor together all the rockers had the same oil coming out. Now i have low oil pressure and the one gushing oil.

There was a thread a few weeks ago about oil that would spray from one rocker arm out past the fender. The fix was replacing the internal pieces of the lifter with a used parts the guy had laying around. He didn't have low oil pressure issues...

My guess is you need another lifter, but the damage might already be done.

you may have bad lifters, but I don't think it will cause a change in oil pressure. Sounds like your cam bearings are worn out...rebuild time most likely.

i hope not i dont really want to pull the motor just yet. expecially with the work i just done. I knew when i had the heads and all off i should of just yanked the darn thing out.
