Cool Oil Pressure

Ok, as some of ya'll know I just recently got doing some mods to my truck (ie lifters 1.7RR's Heads)Among those was of course the valve cover gaskets.I bought brand new OEM replacements...the rubber ones with the steel cores.....The problem I'm having with my oil pressure (manual read gauge) is that as the truck sits there and idles it drops from 60 to 55 to 50 to 45 to 40 psi.....I'm having an oil leak come from somewhere and I'm thinking it's from the DS valve cover gasket...on the back edge I can first off see the gasket popped out and secondly feel it with my fingertips.I have early 80's model 302 valve covers on here to clear my RR's(they're an inch taller) so they've got that little gasket holding lip that curves down along the whole edge.I want to use rubber gaskets but should I be using cork with these.Another thing, these covers should work....all bolts holes in same places just taller and that lip...all things considered...could the leaky gasket be the source of my loss in pressure?Especially when as the PSI drops I'm simultaneously losing more and more oil after the truck has warmed up to normal operating temperature...Geeze this is a long post.Thanks in Advance.

Just trial and error is all. Be happy it's the DRIVERS side and not the passenger side cover leaking.

valve cover gasket is not your pressure problem
60 psi is normal cold and dropping to 40 at idle hot is fine
almost all engines will do this

I agree... on cold start my truck has 60 psi oil psi and then as it warms up it drops. No prob there.
