Got the car running after installing headers and the oil pressure gauge is no longer working. I cant seem to find where the sensor is located on the engine to make sure its plugged in. Ive looked everywhere, but im missing it?

 

Its on the back of the block behind the intake.

 

If you jacked up the engine during your header work, you might have broken the sensor against the firewall.

 

I did jack it up, several times...Thats probably exactly what happened. Will I be able to see this, or will I have to feel to see if its broken. Or should I just go buy one and replace? Is this somthing ill have to order from Chevy or can I get at an autoparts store? THANKS!

 

feel back there or use a mirror on a stick

 

An auto parts store or dealer would have one.
