(1997 stock na beater...https://www.miataturbo.net/forum/t27268/)
We replaced the bottom end on this car and it ran great for a week or two, but now there is no oil pressure until the car has idled about 10 seconds from cold. (Why don't we turn it off!? Because we just want to beat on it and use it until we do a real build on the old block..) The oil pressure goes normal after that initial start up time. We replaced the oil filter and it seemed to shorten the time but probably just in our minds.
Any suggestions?
If it is the oil pump, can it be replaced without removing the engine? This thing gets much better gas mileage the the dually diesel.

Lost this all after typing it...
Try dumping the oil and putting in some walmart special synthetic with a WIX oil filter from NAPA. See if the situation improves. Either that engines is missing all the rod bearing and half the cam caps, or the relief valve in the pump is sticking. Or a severly clogged pickup tube. Did you fill the engine oil with accorns, headgasket repair, or silicone by chance?

It could be that the gauge and/or sensor is going bad after the years, or it could be the oil pump (weren't '97s known for having high rates of oil pump failures?), or the filter, as mentioned. First I'd test with a real (not electric) gauge, then I'd gamble on another filter (since they are cheap) and then maybe suspect the oil pump.

Its so inconsistent, something has to be messed up. Just have to pull it, again. He's got a backlog of cars to turbo, so it will have to get buried in snow for now. :(
No more donuts. Damn FWD.
