120??? wow, that is alot! I currently work at a machine shop which rebuilds engines. And every time an LS1 comes in it it because they have lost compression in 1 cylinder. And every time it is because Of a leaky intake valve.

my factory turbo'd car has 150 on all four. Have you called STS yet?

I know, I'm researching the trade in.

I pulled two bent intake valves out of my car. I didn't realize how common this was with our cars.

NO THATS NOT GOOD!!! Thats a 25% variance which is extreme!!

You better check your oil........ Is it that new metal flake blend?

No but for real was the motor warm when you checked the compression or cold. It will make a difference......Not to mention did you make your throttle body WFO?
