hey guys,

first off, here is a website illustratign what i have found http://www.caswellplating.com/permat...pairprods.html

i actually went to a local napa auto center here and saw this stuff. in anycase, i have read recently about cracked manifold stuff and how people are having a hard time welding it. well here is another solution which should work. Permatex sells a hightemp (up to 2000degree F.) putty which seals cracks in castiron or other applications. Our high temp engines only put out about 1500 degrees F. temps if tuned properly so we should be ok and will probally melt/pop our engiens before we kill the patch thingy.

~cost for a 20 gram pouch is about 8 bucks

goodluck to anyone needing repairs, this does seem like a fairly cheap and easy solution to a complicated and possibly very expensive and mind boggling problem many of us have faced before.

 

Give it two weeks and none of it will be found any place that you filled with it. This stuff is just a temp patch it will not hold. I only wish it was that easy to fix cracks.

 

ahhh so you have actual experience with this stuff?

 

MmMMmm, YES. But great for filling cracks on metal your going to powder coat since it didnt work for what I wanted it for.

 

how big was the crack you filled and where was it at?

 

I thought about that stuff since I used it on an older header that i've since replaced. The only problem I see is ketting the surface clean enough so that it bonds permanenly. After that is done, then heat coat the manifold. The only thing that scares me is if it ever comes off and goes in to the engine.
