where is the spot to put a oil pressure sensor on a ls1? i thought it was on top behind the manifold kinda by the cam position sensor. also is there an air bleed off valve or something back there on top? here is a pic of it. its the copper color thing.

 

that is were they are normally located... That looks like a comp-e-check (SP) fitting...

 

take that out and put it there. that is a connector for a manual gauge

 

Some do it this way.

 

thanks guys. i know i could just drill that piece out but i would like to just do it like stock. why would someone put that thing in there?

 

where did the engine come from?

 

eBay, from a "stolen and retrieved" camaro. looked more like the guy banged a hole in the oil pan to ruin the motor for a new one. the thing was on the motor when he got it so he put it back on after machining.
