Dont ever heat wrap your manifold. I just brought a used dezod kit from someone one here and the manifold and down pipe was heat wraped. The down pipe is in mint condion but the maifold has a few cracks. I will be posting pics up later to show you the cracks caused by the wrap.

 

Yup that's true, this word should spread.. Ive seen a lot off set ups with heat wraps.. Sometimes crack on the manifold is blamed on bad quality but prolly are caused by heat wraps.

 

Well, I wouldn't blame it entirely on the heat wrap. I have a Dezod manifold that isn't wrapped and it cracks like crazy. It seems that everytime I have a crack repaired I get a new one. Some of the weld were not done hot enough and their is very little penetration in the pipe ends.

 

pics of crack does enyone know if its worth fixing

What do you mena by "Worth Fixing"?
do you mean just dumping it and getting a new one? Or running it with the cracks?
Because you SHOULD NOT run it with the cracks...they will just get worse.

 

I would junk it for a tubular. I'd say they are somewhat worth fixing but not worth it in the long run.

 

yea fixing it or just getting a new one

 

If the DP is cracked to, and your gonna get a new mani and dp, I'd get a tubular from TurboToyotas. But I've hae friends that had their mani's welded and they have been fine...but you always run the rist of it cracking again.
I'm assuming you want to save some cash which is why you got a used one, so that's up to you.

 

TurboToyotas manifold FTW (plus its sexier)

 

Thats no good .Cracks in a log manifold just sould nt happen.

 

well...it's not like it's a cast manifold. It's still made with welded tubes...just in a log shape. In fact, I could see it cracking more then an EL tubular mani due to the indirect air flow.
Now if a CAST mani, like the treadstone, were to crack...then there are issues.

 

YOU SHOULD NEVER FIX A CRACKED MANIFOLD!!!!!!!!!!

It just a cheap band aid, it will eventually crack again. You cannot "fix" the original reason why it cracked in the first place. Yes it works, and can buy you some time, but it WILL happen again.

now can heat wrap mess up a header

 

^ yes.

 

Yup.

 

Have you contacted Dezod to see if they will hep you out?

 

Usually happens when the wrap gets wet and doesn't dry properly (ex: turbo timer, air dry if soaking wet) the pipe will crack in due time.

 

yea they told buy a new one. but the gave me like $20 off ther price

 

^ thats pretty ____ty.

 

thats probably not even enough to cover the shipping

how long did you have the kit for?
