32 Buick 57S oil pump valve and spring

Recommended Posts

The 32 Buick is on the hoist and while I was installing the oil relief valve and spring in the oil pump under the engine a very small just over 1/8" stack of washers stuck together fell to the floor.  They came with the valve and spring am I correct to  assume they were above the spring inside the relief valve as a spacer for tension on the spring?  I really would appreciate your comments on this.

thanks much, Jim Jordan

Hi Jim,

I added a just shy of 1/8th in washer to boost my oil pressure about 3psi. It was common practice back in the day, and especially if one were selling the car.! I thought Id try it as my 32 series 90 was running around 27 psi, now its 30 !! Mine fit behind the spring..

Hope that helps.

Hello Steve,

Thanks for the post, I am sure I have it assembled correct from your response fitting behind the spring.  I was running good oil pressure 30/35,  just had the strainer off for cleaning.

I appreciate hearing your comments, big help thanks.
