Oil pressure

Oil pressure
Just installed my new motor ls2 built motor. Iv had no problems with it till one day i got into the car and all of a sudden the oil pressure started to read a little lower then normal. I checked the oil level and there was no problem there. gradually day after day once the car warms up the pressure is sitting at 15 psi. At startup its at 45 psi using 20w50 breakin oil. after a few minutes idling it starts to fall off. The engine sounds fine. and it drives fine. Do you think it would be a bad sensor? while at 15 psi if i just barely touch the throttle it jumps to 35 psi. cruising its sits in the 40 to 45 range. 190 degree engine water temps

Try 5W30 and see what happens!

Hmmmmmm that's odd. Glad I'm not the only one in this boat. Going bring it to the tuner today. I'm going to let him check it out before I go wasting money on another oil change.

do you always have low pressure or just at a hot idle. Mine is only when my oil gets above 230* so Im adding a cooler check this thread out!

When you change your oil cut the filter open with a knife and look for metal dust in the filter media that will tell you if your bearings are the problem.
