ceramic coated header weld crack
looking for a easy fix short of welding the crack in my new headers.
crack is on the #1 primary tube inside the flange.
very small crack but noticeable "tick" while idling.
any good stuff for a temp repair until i get that side off this winter and weld it properly?

I would go ahead and get it welded. The crack will grow and the damage will be worse. If you can find someone that can tig it from the inside the damage to the coating on the outside won't be very noticeable. You can probably touch it up with a little high temp aluminum paint. I've done that before with decent results. If that header has a slip joint on that tube that may be the reason it cracked. If that's the case you will want to add a bolt tab at the silp joint to keep it from cracking again.

ok well I found some sealant at a local spped shop.

they use it for repairs on their drag cars at the track with great results.
they said its next best thing to welding.
I applied and seems to work.
sqeezed some inbetween flange and primary tube and it isnt noticable.
but curing takes 4 hrs .
looks like a good quik fix item for the track

Leave it to Jcwhitey to come with something like that, glad you got it fixed.
Wonder if that stuff will work on a cracked engine block?
My dad has a 94 suburban that has a crack on the side of the motor near one of the freeze plugs, it's kinda of a small crack, worth a shot I guess, that "$25 a can money back garuantee block seal" didnt do squat :shock:
Must be some of that alien technology...lol
