Ok. So i recently got a beater to drive back and forth to work so I could finally put the camaro back in storage. I began last week to take off everything, intake manifold, injectors, intake, valve covers, etc. After everything was spit polished, I put everything back on. Started it up today and had it fully warmed up, checking for leaks, etc. After everything was looking good, I got into the car and noticed the oil pressure guage reading past 80.... Did I hit something during the tear down?

Nevermind. Felt behind the intake and pulled out the broken sending unit.......DOH!

I have a question also.. when I am idling after the engine is warm my oil pressure gauge bounces back and forth a little bit. I was wondering if it's just a loose gauge cable or if something is up with the pressure?

A bounching oil pressure gauge often means air in the oil. On an LS1 that would mean that the oil pump to oil pickup O-ring is bad and needs to be fixed.

But first put a manual oil pressure gauge on it to verify that it's not a gauge/sender problem.

It only happens when it's hot out and im just sitting still and not moving. Whens it cold like it is now it's normal

If this is the case of the O ring, is it a serious problem and is it an easy fix?

to replace the o ring you have to drop the oil pan and take off the oil pick up tube, there will be an o ring on it, just slide it off and put a new one on. It is just getting tot he oil pan that is a little tricky.

as far as if the air in the oil is bad, if the o ring completely fails, then the you won't get any oil pressure at all.
