Hey guys. Been following the "shop area" forums. Lots of troubles and lots of fixes. Enjoy all the back and forth.
I have an issue that has developed that I'd like to poll the "audience" with.
Took the "lovely" beast out for a drive today. She's been running well. But today, as we heading out through the subdivision roads toward the highway I suddenly noticed my oil pressure reading on the gauge had dropped to or near zero. As quickly as I could I looked for a clear spot to pull over (big snow banks), the pressure reading showed normal again. It seemed fine for a short distance and then the whole process went on again. I took a chance and drove home. The drop in the pressure reading happened about a half dozen times on the way, each time coming back within a few seconds.
My thought is "well of course it's the oil pump", and that's my question. Is that the nature of the death of an oil pump, or could there be another reason ? My gauge is of the mechanical type of course. Not original, but a Stewart Warner replacement (2 1/16 in. round that fits in the original military dash), of mid seventies or earlier vintage. The engine is a 235 (1959 block).
Thanks for reading.
