ok so I have been trying to install an oil pressure gauge but cant seem to do it. I have locaed the oil galley plug under the manifold but have no idea on how to take it off. its doesn't seem reachable from the intake. Where is the stock oil on/off switch?? I know its under the manifold but I can't locate it either. Thoughts, help please.

 

have u tried the one under the turbo?? Its a little tricky, but u can do it. just gotta get the right combo of extentions and such to get at it.

 

You will need an allen wrench to remove the plug (I dont think it is a torx/star drive) There is 3 on the front of the block and 3 on the back of the block.

You will most likley need this fitting for the port if you dont have it already...

Hope this helps.

 

Thanks, I'm going to try this tomorrow and see where it goes. The # in the front are under the intake manifold correct??

 

Yes they are a flat round plug, with a hex drive.

 

Im planning to do this mod, what is the normal number for oil PSI on turbocharged cobalt?

I hope this link works but is this what you're talking about? 3 round flat heads with hex?
