Hello all.

I drove my car home a few weeks ago and parked it. Once I went out a few days later to drive somewhere, as soon as I pulled away from my driveway it gave me an oil pressure warning. I parked it and left it. I have finally done some diagnosis. I pulled the oil pressure sending unit and put a mechanical gauge on it. I have 53psi at cold idle and 50-55psi at warm idle. I did not drive around with the mechanical gauge hooked up, but those numbers seem pretty good to me. Anyway, while I was there I swapped the oil filter housing for an aluminum unit (because the bung for the pressure sender cracked out of the plastic as soon as it started getting tight). New pressure sender and again the oil pressure warning light comes on after taking off. Oil is full and This motor was just rebuilt, and the balance shafts were deleted.

Any help or thoughts on what I should do next?

TIA!

Tom
