    Low oil pressure

    UPDATE: Didn’t feel like troubleshooting one thing after another and increasing time and $$. Did all this in one shot over about 20-25 hours of wrenching $400.00 in parts: Pulled: Water pump, thermostat, harmonic balancer, timing cover, oil pump, oil pan, oil relief valve, pick up tube, oil...

    Oil pump install

    Thanks for the input! My guess too, was that it’s so close it would be fine.

    Oil pump install

    I replaced my oil pump and realized I accidentally torqued the four bolts to 20 foot pounds instead of the 18 foot pounds listed. Is that gonna be a problem? Should I take it all a part and back them out and re-torque to 18? Thanks!

    Harmonic balancer pulley

    Does anyone have the “procedure” for installing the pulley? I’ve seen many ways and they’re all a little different with how they do it and torque and angle values….

    Low oil pressure

    My only issues of it just being the pressure sensor are: The first time the pressure sensor went bad, there was a check engine light that said so and it ran fine till I replaced it. The oil pressure gauge was dead as a doornail. This go around, no check engine light, a “low oil pressure, shut...

    Low oil pressure

    Update. Drained the oil. No gunk in it. Swirled it around like I was panning for gold and no metal of any kind…wheew!! Unscrewed the oil filter and no gunk there either. Cut it open and it looked to be in order, but it was rather heavy and the filtration pleats where rather hard. Maybe just...

    That sounds like a plan. I’ll update when I figure out what the issue was. Thanks!

    Low oil pressure

    I did add oil to make sure and the dipstick confirmed I’m in the good, but to no fix. Still alarmed and shut down. I was hoping it would too, but no check engine light like before, and the engine shut off by itself.

    Low oil pressure

    No check engine light this time. Only the red oil can light and the dinging. Then the shutter and shut down. Check engine light only came on when the oil pressure sender code came on a couple years ago.

    Low oil pressure

    Thanks for the replies! I’ve read a bunch about the screen and sender unit. But I think that’s good. Also pondering the o-ring and oil pump. My added difference is the “shutter and engine self shut off”, which scared the heck out me. It will start again. Just self shuts off after a bit. I’m...

    Low oil pressure

    I have a 2013 Tahoe 5.3 liter with about 225,000 on the clock. I had no oil pressure on the gauge about 2 years ago along with a check engine light that said the oil pressure sender was bad. Replaced it along with a new screen and all was good. A couple days ago I was backing out of my garage...
