Those are decent basically normal numbers
what should be the operating oil pressure for a 2.0 aba.
the reason i ask is, I installed my new oil pressure gauge and duing a cold start up it reads 60 psi. and when revved it shoots up to 100+ (im pretty sure this is not correct)
after running for appx 10-15 minutes, the oil pressure gradually drops to 35-40 at idle, and then shoots up to 80+ when revved.
dont know if it makes a difference, but my oil pressure gauge is tapped into one of the existing ports by the oil filter.
what numbers should i actually be seeing? and what could be the cause of this?
