Bentley, I didn’t change the one on the Silverado I was working on. But it should just removing the one bolt. You’ll have to remove the harmonic balancer. That can be a pain. I had to buy the big dewalt impact gun to get the bolt loose. And then pulling it off is hard to it is pressed in by the bolt when assembled. Which is how you’ll need to reinstall it. But use a new bolt when re-installing. Sorry this is more about the balancer than the valve. That’s just going to be your hardest part. If you need more help just let me know. I’ll help anyway I can.

Bentley yes it was the oil pump solenoid. I just got everything back running. I traded mine a few days ago. I changed the whole oil pump and it didn’t want to prime. Mine doesn’t have a fill plug on the side of the block to prime it. I ended up taking the intake off and pouring oil down the hole that is above where the sending unit goes. Mine was a 4 wheel drive so I had to drop the rack and the differential. A lot of times when you drop the rack you will have to have the electric motor on the rack reprogrammed. So be prepared to have it towed to a shop because it’s likely. Like I said, I traded mine in and bought another vehicle. Sorry this is so long. I just wanted to let you know what I ran into and if someone else runs across this it may help them.

Well I’ve changed the oil filter twice. Once with a percolator then a wix. I ordered an oil pressure regulator but didn’t notice that mine don’t have it in the oil pan. After I added back (yes 0w20) the oil and started it back up it ran to 40psi for a minute, but as soon jumped to 60 psi and flashing the light. I have fully turned against all newer vehicles. I’m trading this Chevy in as soon as I get it fixed. Along with my 2015 ram too.

Snowcamo, yea I’m going to. I’m going ahead and changing out the pressure relief valve. I found one kinda cheap but the oil pan gasket was the more expensive part. But yea I have to change the oil anyway so new filter. ember1205, I didn’t measure the amount that come out, but I did measure what I put in and checked the fluid before and after start up. It’s right on the full mark. im going to try changing the valve, oil, and filter and see the what we got.

I have a 2018 Silverado 1500 with a 5.3. Changed my my oil. When I started it up after the oil change the oil pressure went to 40psi but then the second stage on the oil pump kicked in and the oil pressure jumped to 60psi. Easily pressing the gas pedal the pressure raises with how much you press the gas pedal. At 2500rpms it reaches 80psi. Had no problems before the oil change. With the high oil pressure the truck runs like crap and the check engine light is flashing which states that it is or could cause engine or cat damage. All the info for high pressure is either bad sending unit or clogged oil filter. It’s not either of those. New filter, and the engine is actually running bad. The web is flooded with people saying that they have low to 0 oil pressure. They recommend plugging off the oil pressure relief valve to get better oil pressure. I’m wondering if it isn’t that it’s stuck or clogged. Also it’s hard to find a part number for it. I don’t have enough money to pay my bills let alone throw the parts cannon at it. I’m a disabled vet and my wife drives 4 hours a day to and from college. So all our money is spoken for. I need a path to fallow to find the problem.
