is this small crack a cause for concern

[BrandonW]

on the turbo exhaust manifold there is a crack thats small, only the first centimeter or two goes all the way through from where it starts it looks like, i didn't even know it was there until i got it back from ceramic coating it must have been caked with carbon build up the old gasket looked ok as in not rotted out

would have been better if the place that did my ceramic coating told me when they cleaned it up

me.....i wouldnt be concerned
but then again im hardly concerned about shit

 

[GrimJack]

Me either. Run it, and when it starts to actually leak, worry about it then.

Where's IJ when you need him...

I believe he could actually drill a small hole at the end of the crack to stop it from spreading if he really wants to do anything about it.

He could do that. That's what they do if there is a small body crack on an airplane. At least at the Airport I used to fly out of.

Found this online. Brief and detailed about stopping cracks with the drill method.

That would be my course of action

I'd coat the gasket with Copper RTV and ignore it.

Seems like the vote is unanimous.
Never heard of that myself, learned something new today and it's only 7:30am... LOL!

Done it to stop cracks spreading in windscreens as well

This is why you don't seam weld shells to strengthen them, you stitch weld them, if a crack develops it stops at the gap.

Seam welding can also warp the shit out of a otherwise straight shell, correct? Or is that just an urban myth?

I'd say Urban myth, one I haven't heard before now though....

lol, a few people that told me this as the reasoning early on. But I suppose its better to do the right thing for the wrong reason than the wrong thing for the right reason....

Good info Ian! I've already passed my learning quota of the day, gotta go home now and back to sleep

it'll definitely warp any sheet metal but i seriously doubt the whole shell
