Odd Oil Light

Odd Oil Light
I replaced my oil pump (my previous one was fine, but I was replacing the front oil seal, and grabbed the oil and water pumps while in there).
I took the fuel pump fuse out and spun it a few times on reassebly after I had filled up the filter and the sump with the right amount of oil. Have put about 500 ish miles on it since then, and just yesterday noticed that on start up, the normal dash lights come on.. then after about 30 seconds, typically after I am already rolling down the road, the light comes on for 2 seconds, then goes back out. The two times this has happened, the car has basically been idling along out the driveway, so not alot of throttle in play. I checked the oil level (fine), for leaks (none) and the connection to the oil pressure pump. Any ideas? Only thing I could think of is that maybe the brake cleaner I used to clean up timing cover when it was off may have affected something, but I wouldn't think it's that consistant... thoughts?

A manual oil PSI test would be a good thing to try. The oil switch triggers at about 7 PSI. You could also have a stray ground (skinned wire) that comes and goes. You can test that theory by removing plug from oil pressure switch, it won't light up on power up, but if it repeats while driving you'll know it is wiring related.
Of course you run the risk that it is not wiring, you did not scrub any insulation off while wrenching, etc., and that engine is actually loosing pressure.
So do you want to drive around with 23 pounds? Or just replace the switch. But if you don't test you may not realize until later, when engine damage has happened.
I think it was a poor design choice for Rover to not have an oil PSI gauge.

just went out and changed the filter.... on the offchance it was clogged... and once I re did it and started the car, it seems worse.. when I am backing up and the RPM bogs down a bit, seems to exacerbate the light coming on....but when its in park, and RPM is slightly up and seems fine... almost like it's getting worse... Neat!
So with regard to the dowels, is it an issue of installing something, or just sliding the cover back on...
I did replace the O ring on the pick up... I just got one from the autoparts store that fit tightly... is there something else I should be doing other than shooting this damn thing?
