I noticed yesterday my oil pressure was higher than usual, since then everytime I crank my truck the oil pressure increases and is now past the last number (80). Y'all think this would be the sender goin out or the excess pressure valve stuck? I'm leaning more towards the sender because the guage shows the pressure being high before even cranking the truck. Just wanted a few extra opinions.
Thanks,
Jake

It's a Chevy (avalanche). By dash do you mean something with the guage itself or the sender?

First off Oil Pressure is the resistance to flow. THe colder it is the Harder it is to flow. Now that you know this Lets get on topic of your Chevy Avalanche. It is probably a bad sending unit or bad cluster. What year?

Check the cluster. GM's are famous for bad clusters. i have a 04' dmax and 06 Z and both had bad clusters.

It's an 04 avalanche, and the pressure is showin all the way topped out and it's runnin fine so I'm guessin it's te sendin unit.

Mine just went out in my 07 Tahoe... It actually shut the engine down every 150 miles to low RPM. It was sending codes & freaking out... I ended up taking it to the dealer & said F it lol

gauge itself and yes it going to go up some when it get colder but it shouldn't be that much
