When putting the rockers back on they are torqued to 22 ft lbs with loctite on them. The motor is turned 180 and retorqued to make sure they are 22 ft lbs. My question is how long for the loctite to dry? Is there a chance that the first couple of bolts may be dry by the time you turn the motor over and get back to check them risking breaking the loctite loose? Thanks in advance!

I never read in the service manual to use thread locker on the rocker bolts.

Where did you read that?

JMX's how to page. Couple of different items should have loctite on them.

You won't find that in the service manual

Of course, I can't see that it would hurt anything

Do you think this is needed?

Loctite is not specified in the service manual nor is it needed. Is it ok to use? Sure, but way overkill, IMO.

Threadlocker is not needed, but it is a good idea to use some RTV.

What would the advantage be of using RVT on stock heads. I've seen were the ported heads needed some due to the porting going through and the RVT sealing it. I'm not worried about sealing, I just don't want the bolts to come loose.

Also, is using loctite bad on aluminum heads? I was under the impression from a GM mechanic that it was applied when assembled. Thanks for the input guys!

They use loctite or thread sealer due to what John02SS was saying. After porting heads, the rocker arm boss is exposed, and if not sealed it could possibly leak oil through the bolt hole. If you are just torqueing rockers on stock unported heads, then you do not need any loctite or sealant, that's why the service manual does not mention anything.

I didnt see any locktite on my rocker studs when I did my 2000 and I didnt put any back on either

I think there is some sort of locker under the head of the bolt from the factory, but not on the threads. I never use any on reassembly either. I do use teflon thread sealer on the intake rocker bolt threads on ported heads.

Would using a little as suggested in the how to article hurt anything upon removal the next time or just a little over kill. BTW, I like overkill!

Just wanted to bring this back to the top.

John ...

There is no real answer to this. The service manual does not specify thread locker on rocker arm bolts. If you want to use it, go ahead .. no big deal.

Not much more to say ....

Does the manual suggest loctite on any bolts involved in a cam swap?

I use L/T on the cam sprocket bolts. That's all.

BTW, I just removed the rocker arms on a virgin 00 LS1 and there was red L/T under the head of the bolts. It was obvious.

I cannot recall if the manual said anything about it, but the only ones I remember being an issue were the three cam sprocket bolts.
