Hi all,
Trying to figure out why 4 rockers weren't getting oil.
Its a 1976 454 that acquired a top end squeak 15 years ago and I took it out and it sat in garage till now.
Took manifold and valve covers off and while spinning oil pump to observe oil flow found 4 rockers not getting oil.
After backing off rockers, oil flows readily from lifters but when tightened back down it doesn't make it up the push rods to the rockers.
Inspected rods and they are clear, rocker oil holes are good.
Any suggestions on what's going on and what should be next step?
60 psi oil pressure and a brand new HV pump.
Cheers
