oil pressure

Posted by David Grubbs On 2011/7/7 19:04:40

I was driving the 51 200 with the rebuilt 327 around town today - warm about 80 degrees. Temp gauge got to the "M" in temp, so it wasn't too hot. The oil pressure light started flickering, first around an idle - no concern there. But then it starting staying on bright at 30 in 3rd. I have a gauge on it as well, and it looked ok around 35 psi. I did replace the sender after I rebuilt the engine with one I got at O'Riley's. Basically found one that would fit. The engine was originally a 288, but swapped cam/crank/rods etc from a 327 into it. The oil pump was working fine before the rebuild (last winter), so I just cleaned it and primed it with grease when the engine was fired up. I do have the oil pump from the 327 donor engine. The engine now has about 300 miles on it - this symptom started showing up about a week ago - it does seem to be related to engine temp. The oil is Rotella 10-30 with ZDDP added. Any suggestions? (short of more snake oil....)
