Loctite on Flywheel and PP bolts? Torque?
The new GM flywheel bolts came with a blue thread sealer of some sort on them. I know guys like red loctite on flywheel bolts but I have been leery about using that stuff on much of anything.
What are guys using on the flywheel and PP bolts?
I found sequential flywheel torque specs of 15, 37 and 74 ft-lbs and pressure plate specs of 35 ft-lbs. Sound about right?
I found a bellhousing torque spec of 37 ft-lb. I am a big fan of anti-seize on dis-similar metals - especially in aluminum. This is one thing that I would probably not loctite - rather use anti-seize.

The sealant on the flywheel crank bolt is to prevent oil seepage through the crank flange. Use new bolt, red locktite. The 02 LQ4 manual has the same 3 torque specs you listed.
I ALWAYS, ALWAYS, ALWAYS use locktite on the pressure plate bolts. On the torque specs, do some research, there seems to be 2 specs out there. The higher one seems to cause bolts to snap.
Also, do a search in the manual trans section here, lots of good info there.

The crank flange is drilled through to the crank case area.
In addition, the hole for the pilot bearing is drilled through to the 7/8 crank journal. There's just a simple pressed in plug to prevent oil from coming through there. So dont use the grease method to remove the bearing. you'll push the plug into the crankcase.
Yes, locktite on both.
