I had the engine running for about a 30 minutes. Pulled the valve covers off. with engine running warm I tried to locate the bad lifters tried slideing a feeler gauge in could only get it in 1 with a fare amount of force. tried using a stethoscope touching the block next to every lifter and do not here a difference. I did notice 2 lifters with more oil splashing from them than the others I thought they may be the bad lifters. I ran a direct line to lifters bypassing filter. the oil pressure warm is just under 40 psi. I want to make 100 precent sure I replace the correct lifters. I have an oil pressure pot I thought if I hook that up and pressurise the oil system may I could see the bad ones .If anyone has a way to detect the faulty lifter please let me know.
