My 4 cylinder race motor is making to much oil pressure. Any of the race guys know if changing to a lighter spring would make a difference? Anyone had such a problem? Any other suggestions or areas to trouble shoot?

The springs are the same. The piston length is what changes to vary the pressure.

I think something else is wrong. I regularly run 80+ pounds with cold oil and have never had a leak. Others I know have also been OK.
May be somthing restricting the valve or just bad oil coolers.

Ken,

Any ideas of what could be restricting the valve? It seems to simple a setup to screw up.When I took it out it moved freely in the bore. It's unlikely that 2 oil coolers would be defective??? However stranger things have happened.
