did it with the engine.did you replace the oil pump?
the last one i opened up had nothing in it. That was like 200 miles ago so it might have changed. should i do another?At this point I'd be slicing open an oil filter to inspect for whitemetal/bearing material....... :nono:
wrong i compared the picture in the first post to new readings on the stock gauge. its now on the 20 psi line at 3k rpm if the gauge is bad enough to change ~5 psi with no actual change in pressure in one week i am going to disconnect it because its pissing me off.Dude you measured your oil pressure the first time with a mech oil pressure gauge and now you are reading the stock gauge again, of course its going to be different. Like stated its not accurate. Use your mechanical gauge for any diagnosis, the gauge in the car is for reference to see if you have any pressure, a mechanical gauge is used to diagnose issues.
I appreciate you trying to help me but as stated i DID use a brand new mechanical oil pressure tester and i had 33 psi at 3000 rpm and 7 psi at idle. All i was saying is i don't think the stock gauge would vary by ~5 psi daily. which is why i will check again WITH AN OIL PRESSURE GAUGE.Last time you checked what? Your stock gauge? Take everyones advice and stop diagnosing your engine with the stock gauge.
I wish you guys would STOP posting this dribble like it's fact and that "Toyota" designed the Oil system in a 7Mgte to behave this way..... :nono:If you dont mind I would like to jump in on this. I bought my car back in the summer and I was worried but Toyota use high volume, low pressure oil system. My oil pressure reads the same as yours. I am thinking about doing the 5mm shim on the oil pump relief valve. It is a quick upgrade. They say you get 10 to 15 on idle and about 50 to 55 max. The oil filter housing also has a relief valve and they said it was set to open at 40. Something to think about and they do have it posted here on a thread. Search for shimming the oil pump. Make sure if you do shim the relief valve in the oil pump that you dont go over 5mm. The CT turbo does not have no inlet restriction oil feed and they say to much oil pressure can make them start leaking oil.
not that i know of. car doesn't smoke at all. Is it possible that the pressure is going down because it keeps getting warmer out?I suppose you don't have any issues with your valve seals leaking? I've notice that running full synth oil vs. dino lowers the pressure in my car.
