Loctite IRL vs FSM

Hey guys,

I have the FSM, but was wondering if the gurus here could give me some practical advice from life experiences.

Should I use red loctite on:
Flywheel to cam
Clutch Plate to flywheel
Exhaust Manifold to block
Exhaust/Intake manifold to block

Should I use blue loctite on:
Exhaust manifold to towntube collector
Carburetor mounting studs
Oil Pan bolts
Bellhousing to block
bellhousing to AX15
U-Joint retainers

I'm getting gun-shy on this project. I've rebuilt older chevrolets before and I've never had this many bolts snap on me (yes I used PB Blast, yes I let it sit and reapplied, etc)

I appreciate your advice - D

No on the exhaust/intake manifold to block.
No on any thing but anti seize on the exhaust down tube.
I would not waste time with putting anything on the oil pan bolts. Or the engine to trans bolts.

I have only put together and couple hundred of these engines, so do as you want. If I find a issue that needs a locking fluid I use it. If I dont then I dont worry about it..

I didnt use locktite on any of those bolts when I did my engine and trans replacment. I just torqued them to spec. 5 months 20,000 miles no issues.

Don't bother with loctite on the exhaust at al. The heat will neuter it and it won't hold anything. The only place I've ever used loctite is on the connecting rod nuts. Its the only place that really needs it. Otherwise just be very clean, no crap in the threads -- and torque it to spec as Siva says. It'll hold.
