Need Help
I have a 2007 silverardo Z71 4x4 LTZ with a 6.0 vortec max. The truck has 105K on it. Runs great. The oil pressure gauge starts to drop after about 50 miles into a trip. It falls all the way to zero and sets off the alarms on the dash. There is no lifter tap or knocking at all the truck seems fine. I replaced the oil sending unit about 2 weeks ago and thought all was well. The problem has returned. Any help would be great.

The oil pressure sensor may be causing the problem. This is just a suggestion, not a diagnosis. I encourage you to take the vehicle in for an inspection. A certified technician should be able to offer a more accurate diagnosis after a physical inspection.
If you have additional questions, please feel free to contact me.

I had the same issue happen once to me, and believe it or not, I was about a qt short on oil after an oil change. I put in a quart and the problem went away...I wouldn't have thought it would drop pressure to 0 but it did.

The oil is dead on full on the dipstick. I was told it could be in the cluster. I know the old body style trucks had cluster problem not sure about the new ones. Its driving me nuts!
