Just wondering what everyone is using on the threads of thier intake manifold bolts. Some say blue loctite and some say use a thread sealer. Forget which one ls1howto says, but i think the service manual says to use some sort of sealer compound?

any help?
thanks

 

anyone?

 

I've never used any sealant/threadlocker on mine.Never had a problem and my intake has been off a few times.I just torque it to specs and fire it up.

 

Use teflon paste thread sealant....That works the best, but any type of non-hardening sealer would probably be OK.

The teflon paste should be available at most auto parts stores etc.

Thanks, I appreciate it!

 

ive had mine off a few time never once have i used anything on them.mines ok. you know the torque specs right..first pass 44in second pass 89in..but you have to do it in a certian order (forgot without looking it up)

 

I think you are confusing using thread sealer on the rocker arm bolts that protrude into the intake ports on ported heads. Intake manifold bolts do not require any sealer or loctite.

 

The assembly manual says:
"Apply threadlock GM P/N 12345382 or equivalent to the threads of the intake manifold bolts."
12345382 is Permatex Medium Strength Threadlocker Blue p/n 24206.
