Oil Pressure Issues

[bkawasakiyee]

I had an oil pressure light come on yesterday. Drove home from work (about 30 miles) and pulled into the garage and the oil pressure light came on and the dash was reading 8-9 PSI at idle. I shut it down and checked the dipstick and everything was reading fine. I started it back up and the light was still on.... Reved it a bit and the oil PSI would climb but drop back down to 9-10 PSI. Took it for test drive this morning, got the truck warmed up and same thing, pulled into the drive way and the oil pressure drops to 8 PSI. Any ideas on whats going on here? I have a trip planned this weekend but am worried about the truck.

That’s too low , mine drops to maybe 30-35 psi when stopped .

I'd have it towed to the dealer for an oil change. Hopefully that fixes it and flushes something out. If not let them diagnose it before you need a new engine. Might be a bad sensor. Might be a bad motor or oil pump.

Stop driving the truck.

DO NOT DRIVE THE TRUCK. tow it to the dealer.

Might be the platic valve in oil cooler , wellknown issue in europe

Mine seems to drop to 20 sometimes when I idel. Are you never going below 30?

Wonder what the difference is for the 5.7 vs Diesel for idel oil pressure

lol when I’m at a stop light light the lowest mines gone down to is 32 psi

Mine

Could it be down to different engines? Not a engine guy so idk.

I assume the engine would matter but IMHO no engine should drop below 20-25 psi oil pressure

I wonder if Op ever found out what is going on with his motor?
I finally remembered to check mine today at lunch, had the truck idling for a good hour while on lunch and it dropped all the way down to 18 psi and the engine oil temp was 210-214 is that normal for these motors?

Sounds like it may be normal, based on my experience so far. And some other people who are in that general range. I have a Gen3 EcoDiesel.

Mine at idle.

 

[JJRamTX]

Wow, that seems way to low. I don't think I have seen mine below 45 psi...

I believe though this thread is more geared towards the diesel engine. Not the 5.7 hemi. Probably difference in psi between the two.

My EcoDiesel idles at 19-20 PSI, I thought it was low as well, but after talking to other EcoDiesel owners that seems to be the normal idle oil pressure. I was concerned at first too since I was so used to what my 5.7 would idle at.

That said 8-9 is way low and yes, don't drive it, have it towed to the dealer.

Thx for confirming, I figured this was the case.
