Ya know I was in the bottom of my sa the other day and didnt even think to look at the pump, just replaced the pan gasket. I am looking at a service manual now and that cover looks like its a cast unit. I cant think for the life of me that could get warped. If its cast, it would break first unless it was a lousy casting to begin with. I would replace it to be on the safe side or at least go to the dealer and look at a new one to see what I was up against. Also I forgot to mention that the clearance between the gear teeth and the housing its self are critical for good oil pressure as well.

Specs for sa: body to gear running clearance .0053-.0083"

End clearance .0035-,006"

They dont list a backlash but I suspect the min. should be .003"+. You probably have more like .006-.010.

If you keep the numbers on the clearance in the range that I gave you, you shouldnt have any problems getting pressure. I think the pump gasket should be about as thin as celophane and I never used sealer but then again I had perfectly flat surfaces. I still wouldnt use sealer, even if I was throwing it back together. Might try hi tack but there just aint supposed to be none there. Remember the clearance issue??

Post back if I can mess you up anymore.
