I'm prepping the car for racing at Barber over Labor day. Got all the fluids changed and cranked it up. It's been many, many months since it's been started. It started right up, but the oil pressure seems low. I was seeing around 20psi right after it started. It's in the 80s outside, but I would expect the pressure to be a little higher right after startup. I'm running redline 30wt racing oil.

I have an electronic gauge and the sending unit was seeming a little flaky last time out so I'm going to get a new one and see if I get the same readings. If I still get low readings, is that pretty indicative of a weak oil pump? Could it be anything else? No major leaks that I see.

How involved is replacing the pump? It doesn't look too terribly bad. I just picked up a spare pump from Tristan so maybe that's why it went.

Thanks.
