have low oil pressure, 14 psi @idle, 30-40psi@3500rpm--
starts at 70 psi then drops within 5 mins...
??? could I have bad parts inside..oil pump, pressure regulator or o.p.adjustment screw, or does this sound like the engine is krap?????
should I replace parts first, or just replace engine, and do you have suggestion re complete engines?

 

the stock gauges suck *** get aftermarket ones

 

WOW i get like 60psi @3000rpm and i run a stock gauge!! the maual says oil pressure at 14psi at idle and like 40-60 psi at 3000rpm i think u have probs, PEACE!!

 

Sounds like you might have a problem with your oil pressure regulator,oil thermal pellet,or a bad pump.
But does sound like your thermal pellet.
Good Luck

Do u have a S4 or a S5 Rx-7. The S5 metering pump is electrical so check the pump to see if its functioning properly. the way it needs to be tested is to acutally measure hoe much the metering jets pump out in an alloted time period. Also, check your oil and change it regularly. Also the Stock oil reader does suck donkey *****.
