117K miles. Low oil pressure when I'm stuck in traffic or idling only. Dealer and a couple other mechanics checked the sending unit and it's OK. After reading various posts in this forum, I also tried a thicker oil 5-40 but still no help. Everyone tells me to get a rebuilt engine. Anyone knows where I can get a quality rebuilt engine and installed? I live in Pinole, California.
I also have a "Service Ride Control" and my auto-leveler doesn't function anymore. Not sure if this is related to my low oil pressure.
Any help or advise is appreciated.
I had the "low oil pressure" warning once and then changed out the o-ring. Mine would hover around 1/4 to 1/8 on the pressure gauge, and now its between 1/2 and 1/4 . Took the truck on a 3000 mile road trip and didn't get the warning once after changing the o-ring, so I think its kosher. Most peoples gauges seem to be around the 1/2 mark all the time, but unless the engine is making all sorts of clattering sounds or a bunch of other racket, you probably don't have a serious issue. Mine still even sounded just like a Cadillac should before i changed the O-ring.
And did any of these shops actually check the pressure with a secondary gauge on the oil filter connection?
From my experience with these the oil pressure gauge and warning system is kind of finnicky and gives false readings on occasion.
