Just finished a rebuild!

[deuces]

I just got my motor rebuilt due to fried piston rings. Now I've been driving it for 5 days, I put on 200kms and now I got a oil leak. I've also noticed that the oil pressure guage dont move so its got me worried! I was told that most likely it's the oil pressure sending unit! Doe's anyone have any suggestions?

Try to hook up a mechanical pressure gauge in the engine compartment, just to make sure you do have pressure. If so, replace your sending unit. As for the oil leak, find it and replace the gasket

Sometimes the opsu needs some teflon tape.

Yea mine leaked after replacing it and I put teflon tape on it. just afraid I was going to break that damn small thread off in there.

so i replaced the opsu and yep, that was the problem! But what a pain in the arse to remove it!

Where is the opsu on lt-1's? I thought they weren't in the back like the ls-1's.

They are in the back behind the intake and at the top of the block deck same place since birth of the small block chevy
