REPAIR HELP PLEASE!!!

I haven't had a turbo or manifold yet on a piece of heavy equipment that I couldn't get off using a ratchet or a wrench. Hell I pulled the manifold off my 40 year old 3406 that sat in a field for 10 years with no heat, no penetrating oil and basic hand tools.

Penetrating oil is a fallacy IMO. Never had any luck with it. Only thing it kinda helps with is lubricating any exposed thread. Even then a quick buffing with a wire wheel on a die grinder usually achieves the same result.

 

I feel personally attacked

 

I ran into another owner operator out here on the road he said I should take it apart & use JB weld on it let it sit for 24 hrs & it’ll be fine thoughts anyone

 

They make a high heat JB Weld that's good for 1000°F continuous. Not sure how well it'd stand up. Have to remember that the crack will likely keep propogating until it breaks completely through the manifold or it spreads to a heavy part of the casting and slows/stops.

Doesn't hurt to try but epoxys like JB Weld are usually used to bond 2 surfaces together, not as a coating over top of something. Worst case scenario you try it and it doesn't work. Its only $20 you're out.

 

My mechanic said be careful bc if it sucks into the engine I’m done! Is there a chance at that happening?

 

just keep driving it like you been: it will get you to where you’re headed a lot faster than fixing it.

 

That's much more eloquent than what I was gonna say.

 

Have you heard about cold stitching? I was advised to do it to my block instead of welding

 

Never heard of it but sounds interesting. Please explain

 

I’m wondering why the manifold and turbo need replacing? Only the manifold’s cracked? Turbo cracked too?
