Oil pumps for SBC

<< < (2/2)

Paul New:
What block are you running?

Ok, after research and disassembly, no visible defects found in oil pump or drive. No debris found in screen or pump (Melling HV). Apparently " thick oil may cause pressure relief valve to open prematurely".  A new CVR pump is on it's way. I have a flat tappet cam/mech. lifters and have never ran restrictors except with roller cam/lefters. If I still have too much internal leakage, I'm thinking that restricting flow to the top end will be the next step. More delays ::) I'm ready to smell tire smoke. Thanks for your inputs.

FWIW
Most lifter mfg's say no restrictors
The bushed wheel lifters should Never have any oil restrictors per Mr John Callies
maker of Morels ( he invented those)

afaulk:
Oh yeah, Paul it's a Milodon aluminum block
