I'm trying to decide whether my oil pressure light being on is an actual pump failure or something else like a faulty sensor or light. Needless to say I'm thankful I haven't seized the engine already and I'm going to avoid running it until I have it figured out.
I have seen at least one other thread where it was a pump failure. I'm going to continue doing some searching but curious if anyone knows a good test for the pressure sensor. I had recently changed the sheaths on the wiring from the oil sensor under the sprocket but don't think that would have affected anything.
On the one hand the pump would make sense and not be the end of the world to have to replace. it would alarmingly justify the smoking header pipes and spark plugs getting very hot in short time (perhaps that's normal?). I unscrewed the front right (exhaust?) valve cover and while there was dampness in there I didn't see any oil flinging out.
On the other hand, the oil level does go down in the site glass upon turning over and goes further down under revs, almost out of sight. With re mentioning that my oil filter was missing a washer between filter and spring which I'll replace next change - wouldn't think that would drastically changed oil pressure
Any tests or suggested next steps would be thoroughly appreciated!
