I have seen the spring bent and also broken. Both caused the valve not to seat. I have pulled the valve out, polished out the groove, reinstalled it and stopped the excessive oil drain. Fix the pressure relief valve and/or the spring and you will basically eliminate the problem.

Dennis Savarese" Subject: Re: Yak-List: Kimball Clean Kit It's under the cap where the oil pressure adjustment screw is on the right side of the oil pump. The adjustment screw applies the pressure to the spring that pushes on the pressure relief valve. Remove the cap on the right side of the oil pump. Before you remove the adjuster screw etc., rotate the screw counterclockwise and count the number of turns until it comes out. That way you'll have a starting point to resetting the oil pressure. Loosen and remove the large nut and pull out the spring and valve. Check the spring carefully. If it is bent in anyway, replace it because the bent spring will not allow the valve to seat properly. The valve itself will have a groove in it from where it seats against the valve seat. The valve seat is not like a normal valve seat which mates perfectly to the valve. It is nothing more than a machined hole. That is why there is a groove around the valve. So don't try polishing the seat. Just make sure there is no buildup of any kind on the seat and it feels smooth to the touch. You can polish the valve to remove the groove and reinstall it. If the spring is in tact, flip it 180 degrees and reassemble everything except leave the cap off because you will have to adjust the oil pressure. Turn the screw in the number of turns you counted when you removed it. Then run the engine and reset the oil pressure to the desired level.
