GM spec on the plastic LIM gasket is 13ft lbs. I use 15ft lbs on aluminum LIM gaskets. Be careful torqing them, the head on the bolts are 3/8" not 10mm. A 10mm socket frequently rounds the heads.

SC to LIM bolts are 17ft lbs.

I really want to kick someone about those bolts. Lets make it all metric, but throw a standard bolt head on there just to confuse people.

It'* the only metric socket I have for 3/8 drive stuff. Throws many folks off because the etching is worn off as well and it sure looks like the 10mm.

Dan, wait til you get inside the motor. All the bottom end bolts are standard as well.
