Research carefully. Rick.
All Chevrolet small time engine builders I know use the factory GM
bolt in oil filter adapter bypass valve.
Its discontinued by General Motors.
Available new aftermarket by Dorman.
Push down on the disc valve with a small screwdriver.
Feel spring preload. Not sure of Blowoff pressure specs.
On Pontiac, Olds,& Buick V8 engine it only takes a few pounds pressure to open.
Chevrolet seems to use a stronger spring to seat phelonic plastic disc tighter.
Likely going to use an aftermarket Moroso billet aluminum oil filter adapter with no bypass valve on my 410.
