Thanks Chevy, you are talking about the Oil sending unit? Also did your oil pressure drop to 0 (zero) when you were at idle, example when you were stopped at a stoplight? Then as you took back off the pressure came back up.

...or is it the oil pressure switch?

My advice:fc5716bd: wait till the engine is cool. I did it hot. It's in a awkward spot right up on the firewall and burnt my arm and dropped the old oil sender unit. Drove it yesterday and today so far haven't heard it get caught on anything or rattle around. That being said it's fairly straight drive.

The work isn't hard your just doing it in the blind. I googled oil sender locotion gmc and engine size you should see some pics of it too that help for reference.

LOL!!! good one JC

..... I'm gonna run it through the Dealership and let them check the oil pump again. I was going by what the previous owner had told me, he had said it was check and they told him that it was good. I figured I would get a second opinion.

Whats the dealer say? Mine never bottomed out at 0. It was only there when turned off. Even if I slammed the gas from stop I couldn't get the needle to move. Again, the actual replacement wasn't hard. Getting to it was the pain... Oh and not dropping it.

Dealer said pump is good and manually check pressure gauge (dash), gauge is good. They are thinking the cam bearings are just wore out. Sounded odd to me, so I have know clue which direction to go now. I'm just thinking of dropping in another motor and be done with it.

options...

1. new motor
2. motor rebuild (gives you a chance for some go fast goodies possibly)
3. trade it in for something else
