My still-isn't-installed LS1 had a couple of problems I needed to fix. One I knew about as soon as I got the engine, the other I found out later.

The power steering pulley was the victim of the PS cooler being packed right in front of it, apparently got smacked by a forklift or something, busted the rim off of the hub. I told the seller about it, he sent me a new pulley. Finally got around to putting it on tonight.

The other was an exhaust manifold bolt that was broken off. In removing the others, I discovered they were hard to remove. Reading the shop manual, I see they are Loctite'd - didn't know that before. At least it was easy to get to, and for once the easy-out actually worked. Threads in the head look fine.

Next up: Engine mounts.

 

Cool, sounds like you lucked out.

 

Visions of helicoil were dancing in my head. . .

If I had known about the Loctite prior, I would have added heat. I just assumed they were seizing and anti-seize hadn't been used. It's gotten me to thinking about Stage 8 or some other type of locked header bolts, and using anti-seize on the threads instead of Loctite.

 

Yep, this will be the second build that I've used the Stage 8 locking header bolts. I used 'em with my SLP headers (eight years ago now! ) & combined with the header gaskets I used, I never had to touch 'em once in all that time...

Engine mounts were a PITA for me, but I used electrical tape to tape a couple of wrenches together so that I could reach all the way that I needed to, & used masking tape on the back of the "business end" of the wrench so that it would hold the nut to the wrench until the bolt threaded on to it...

Have fun...

 

Stage 8 for me... They are really nice pieces. And I can attest to Stage 8's customer service. I wasnt happy with the corrosion on my first set. CS told me that wasnt normal, and to send them the bolts. I did, and a brand new set of bolts and locks showed up a few days later. I was a happy camper.

Just make sure you use a dab of antiseize on the bolt threads to prevent galling.

I'm dropping the a-arms to replace the front springs, so the bolts will be easily accessible. Learned that the hard way on Berlinetta #1.
Absolutely. The Loctite acts as an assembly lubricant, but exactly the opposite if/when you want to remove the bolts. Aluminum and steel don't play all that well together, I'm surprised the factory didn't use more anti-seize (at least, I haven't seen any on the few bolts I've removed so far).

 

I re-used the stock mls header gaskets with the stock bolts and anti-sieze no loctite and two hard seasons no troubles here
