ive asked this question elsewhere, but to no avail. Need some advice from anyone running an RB20DET, and using an aftermarket oil pressure gauge.
finally got my oil pressure gauge in on the 31. Did an oil change while i was at it (naughty me, 2 practices on the same oil and she's black as hell). Admittedly i changed my grades of oil (as i had some sitting around from drift school) - gone from a 10w30 to a 20w50...........wouldnt have thought that would make THAT much difference tho
started it up, pressure started at 30psi..........after about 30sec i hear a warning beeper going...........look into the cabin and see the gauge at 2psi.........turned it off, checked under the car (no leaks etc, nothing wrong). Started it again (mind u, its running EXACTLY like it always has), back at 30psi, and after about 15sec the oil pressure is dropping off back to 2psi again
im confused. is my gauge knackered (its brand new), is my sender knackered? I know it couldnt be a true reading as for that low a pressure the thing wouldnt be turning over. There aint no death rattle, nothing like that. Wont get a "legal" chance to take her for a drive on the street till at least next Monday, so wont know how it behaves under load until then.
any advice/feedback is appreciated
