Good lighting is important, to see the reflection of metal particles. Look at the whole filter inside as you take it apart, checking for collapse, etc like in the photos above.

I hit 5K in my dump run pickup with my stock 400 on highway on ramps. Change the oil and filter first, get a hand help diagnostic gage too. If it changes at all in the wrong direction, I wouldnt hesitate to pull it. Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.

Now unless you are running a all out racing engine 40-60 at cruise and low as 10 are perfectly OK. Around 14 years ago I had to call Chrysler engine hot line about low oil pressure for a 3.0. The first thing said was did it have at least 4 psi at idle No I said it had 7 I was told do nothing as there was nothing wrong with it In retrospect The car continued running with the low pressure for years body went away and car was finally junked witha bad trans

Quote: First thing I'd do is try another gauge; then cut the oil filter open and inspect the element for bearing material. Could be bearing clearances too large, oil being aerated, maybe the filter going into bypass. Sounds like the oil has to be cold (thicker) or the pump spun up to maintain oil pressure, which sounds like an internal (pressure) leak. It doesn't sound fatal, but it doesn't sound right, either; mine have always idled hot with at least 30PSI with a stock pump and regardless of mileage. i'm wondering why if when the motor was first fired. At idle it held about 30lbs hot. Not its dwindled down to 15. Any other suggestions? Could a faulty pump/spring be the culprit? He has a oil idiot light for 15psi and a autometer gauge. light comes on and the gauge shows 15 at hot idle. so we dont think its the gauges fault. Anything else we can check besides pulling it apart? Its been through a couple oil changes with no change in pressure. thanks.

Around 60 when its cold. Been this way for 6 years, still runs ok. Since the day i got it, it has been ticking like its got a wiped cam or lifter, and has this same oil pressure.

I have had cars that ran like that without an issue. But if the car first was run with very different psi numbers something changed and that would worry me. 2017 Contusion Blue Challenger T/A 392 M6 "BLKNBLU"

My '93 Sub has 244,000 miles. When I start it up cold, the oil pressure will be about 35 psi at idle. When it warms up thoroughly, the oil pressure is around 10 psi at idle. get just a little off idle and the pressure comes up to 20, and it stabilizes at around 50 at cruise. I think what you have been describing is an engine set up with a little extra clearance in the bearings. The oil pump delivery is almost exactly proportional to rpm. At idle the pump can pump its entire output through the bearings while developing a pressure of whatever you said, 10 psi or something like that. As the engine speeds up, the oil volume delivered also increases and now you have "normal" oil pressure. If you want to tear down the engine do it. Or, drive the car. It has gone 10K miles already and not locked up, so it must be doing something right. You could also add a couple of bottles of special super-thick oil goop like Wynn's Motor Honey to get the viscosity up. R. A high-volume pump may be the answer if you can get the pan off without yanking the engine. If you do this put in a new high-quality oil pump drive.

The oil pressure works like a tack and will go from 10 to 70 with the rpms. I do keep the idle real low though. I also notice if i shut down the car for a few minute(it cools off i think) and restart it at idle the pressure will be more on the 20 side. Seems the heat effects it a whole lot. Been driving it for 2 summer like this now and so far no break down. Read alot of post and i hear dont worry about it and i also hear tear it down alot. I chenged guages and sending unit to make sure that wasnt the problem it stayed the same. I would blame the pump myself i'am unsure whats in mine or mileage also but someone told me that it sounds like they threw a high pressure pump in for racing by the way it acts.
