Max,
I bought the VDO gauge and sender from Bus Depot. It all came together. Hopefully they put it together matching. Never checked it though.

Driving the interstate at 65 mph, oil is at 22 psi, drove for another 40 miles down to the exit ramp and oil pressure light/buzzer goes off at the end of the ramp. PSI was at 6 at 900 rpm's. Is this common? Or is there a problem with my new GOWESTY engine that has 3000+ miles on it ?
