Hello i´m new here

Just kidding.....sorry, I digress.

If you've gummed up that bolt with glue, I'd get it out of there, and chase the crank threads to get everything cleaned up.
Get a new bolt, whether GM or ARP. Follow the service manual procedure to the letter for torquing, and you will be fine. Depending how long this has been going on, I assume you'll replace the balancer, and might as well do the oil seal.

Here’s what I’ve installed on a friend’s C5 LS1 – The Summit Damper is very well made & has a reasonable price.

Also check out the damper holding/rotating tool – I haven’t used this tool – just ran across it in the catalog.

The SLP UD Pulley is a nice piece. We keep them in stock. It comes with a new GM Crank Bolt and we can get you the proper Serpentine belt you'll need as well.

$179.95 - SLP Underdrive Pulley

Nice product from the description. I like the high retaining walls.

Many have installed an under drive pulley and have been happy. I stayed with the stock size as I feel the five HP gain isn’t worth any potential issues.
