This is for the exhaust header flange nuts. They are already a bit corroded but still thread. Spec's say to use Lock 1 which I believe is Loctite - Blue. But I've seen threads here that recommend anti-seize and given the corroded nature I'm wondering which way to go here.
I went on the other threads recommendation and applied antisieze.
I had to finally resort to a torch to remove one of the stud nuts last year. I also used stainless nuts when reinstalling, which I got from Lowe's.
yeah I should probably use new nuts as both the nuts and mounted bolts are suffering from early stage of corrosion
I'd go with anti-seize. Heat is pretty much the prescribed method for removing a lock-tited nut, so where does that leave you.
FWIW you can buy a box of proper copper locking exhaust washers from an Au-Ve-Co or WURTH distributor for about $15. Use once (w/anti-seize) and toss. Nothing worse than having the top nut on your vertical cylinder's exhaust flange loosen up in the middle of nowhere. DAMHIK. :bang
Your going to want to go with the anti-seize. The heat from the header will cook the loctite and the anti-seize will make sure things don't freeze up.
the loctite brand silver anti seize works well in general, but there is a nickel based type for higher temp things.
