I believe a completely dead OMP would cause rapid wear that would soon kill the engine, but the presence (or lack thereof) of that small amount of oil would not change the way the engine ran until the damage was done.
the pump just died (or something!) in my 79, and its hard to explain but the engine as it runs out of oil will make a fluttery/scraping noise, the seals start scraping on the housing, but its cyclic, because the seals are moving.
diagnosis was easy, i threw some premix in the tank, and it shutup, and it does run a bit smoother too.
omp tests are a couple days away, mines pumping, but its full of air

When I did my test of the OMP, I used my drill to spin the OMP which spins at around 3400rpm. One large factor I forgot to realize is the gear reduction that takes place while the OMP is driven by the engine.
The OMP spins much much faster then I would ever be able to spin it with my drill and HAILERS on the other forum did the test while it was on his engine and the PSI to raise about 40psi as the rpms increase on ONE line while the others were blocked. Same test I did except it was on the car.
So just to correct the info I put up.
