Type Thread Inserts Exhaust Threads

[Guest]

I been using the copper coloured Time Serts for all my cylinder head spark plug holes. I finally got a Time Sert catalog and the time serts are either carbon steel or stainless steel? No Mention of copper plated spark plug inserts? I wondered if they had changed? I bought the time serts years ago. Also what would yo usuggest for repairing the exhaust threads? Wondered what you had luck with? Thanx Mike

Cad plated or yellow zinc plated can look like copper

Yeah thank you, you're right. I put quite a few time sert spark plug inserts in heads (thanks steve rice!!!) and they are awesome, helicoils suck so much!! I wondered if I should put stainless steel in the Heads because stainless and stainless welds itself together!!! I use stainless socket head cap screws, I hate the look of those shcs when the heads rust on my bike and prefer stainless but I've also had stainless electro galvanically seize together Might Impressive when they do and it sucks, Perhaps there are other thread inserts (besides helicoils ) you guys use with success? Thanx Mike

Use locktite for ss to ss to greatly reduce the galling effect.

Not anti seize? Black nickel based 2800 degrees Like used in power plants?

Antiseize on all stainless bolts.

Anti seize works, locktite works just as well, in non heated applications I should have noted.
