I've blow two Earl's oil coolers out with much oil leaking out. My oil pressure
gage reads very high (90-100 psi) and I suspect high oil pressure is causing
the problem. I checked to see if the oil pressure relief valve was stuck but it
came out freely. Diagrams of the relief valve show a sealing washer between
the relief valve cap and the block but mine did not have that sealing washer.
Could that washer (or lack of) be responsible for letting the valve push
further into the block and hence making the spring compress more requiring more
oil pressure? If anyone knows how thick that sealing washer is please let me
know. I'd guess 1/8 inch or so. I guess that could make a difference.
Thanks

What is normal for a 1300 race engine? And how best to decrease oil pressure to
normal?
