If you are running a Corvair or VW based auto engine from the mid to late '60's (sorry, didn't read the whole thread), 25 psi at full operating temperature is normal unless you have a high pressure / high volume oil pump. Typical bypass pressures are cold and will run about 60 psi... remember, when that thing activates the oil you are getting is unfiltered!

Once the engine is hot it doesn't do much at all, it only regulates (bypasses) at a set maximum pressure. If your engine is not quite so new the oil pump will not be able to reach this maximum pressure with hot oil. The only sure fire fix is new bearings and a new oil pump. Paul Smith Brisbane, AUSTRALIA pk.sm...@bigpond.net.au http://kr2spacemodulator.blogspot.com/ Re: KR> oil presure regulator A quick and easy way to increase the presure is to pull the sping out and pull it to strech it out a little bit. Just put it back in and that should dothe trick.
