I would take a can of gunk motor flush and flush out the block.Then give it a fresh oil filter, use normal 10w40 oil not 50 weight racing oil etc.

: I have a 67 Olds Cutlass Supreme with a
: 400ci/auto. It has not been driven much
: since 95 and I purchased the vehicle 9
: months ago. There has been some leaking from
: the engine and trans and I thought the
: gaskets hav dried out some. I had put approx
: 300 miles on it and she runs smooth and
: quite. All of a sudden oll started blowing
: out from the oil filter adapter so I
: replaced the gasket. The first thing that I
: check in was crankcase pressure and there is
: no blow-by and the pcv ssystem including
: hose is good. I hooked up a manual oil
: pressure gage and it reads 50psi at idel and
: increased to 75psi at 3000rpm. I'm thinking
: it must be the oil pump...Am I on the right
: track or what advise can you give me.
: Thanks, Dave
