Hi everyone. It’s my first time here but I need some help. My 2007 Silverado with an LH6 5.3 DOD motor has intermittent oil pressure issues. Alittle back story, the truck has 274k on the original motor. Recently, I replace the valley plate gasket, but only the outer part. For convenience sake, I left the DOD tower gasket part. After that, I replaced the oil pickup tube o ring and gave the truck a full service. My issue now is, I still have intermittent low oil pressure. I’ve read about a service bulletin where the oil pressure relief valve sticks, which requires replacing the oil pump and such but there are so many possibilities I’m not sure what to pursue. I know the oil pressure sensor is good and the screen below it is clean. The issue happens randomly. I can start the truck and it will idle and warm up fine (maybe slightly lower than usual) and then I can drive it. I’ll be sitting at a light or a stop and I can slowly watch the oil pressure fall off. Sometimes even while driving slow and then the oil pressure stays low or 0. It doesn’t cause any bad noises that I know of because I shut it off immediately but I’m so confused. After letting it sit for a bit and starting it up it’s fine. I’ve heard many possibility between it being the oil relief in the pump, the oil relief in the pan that apparently exists, DOD lifter problems (although they aren’t giving me any bad noise) leaking DOD valley gaskets (the ones I skimped on replacing) and more. I’m lost as to what to do. Can anyone offer some insight?
I own a 2004 Chevy Silverado 1500. 108,000 miles, have had a remote starter in it since it was new. Just recently a problem developed. The remote starter will activate, the truck starts but cuts off quickly, the vehicle does not continue to run. With this, I have noticed that the cruise control won't activate once I start driving. The left turn signal doesn't "blink" it stays on steady, but the right signal works fine. However, the turn signal and the cruise control will sometimes work normally. Any suggestions where to start after: The fuse is fine, and the brake light switch seems to work normally.
