I found something that can finally fix the leak in the #1 Slip-In primary of the Jet-hot's and Hooker's. It's the cement they use to connect furnace and fireplace pipe. It's called Furnace Cement and it's made for temps up to 3000deg. I found some at the hardware store, and I bought an 8oz. tub for I think $3 and a putty knife to spread it on the primary. I let it dry for about 20min and then started up the car to warm up the headers, and drove around for about 20min more. When I got home it was completely hardened and there was no more leak. Hope this helps those of you with the leak. I figure it' s atleast worth a try for $3.

 

Hmmm...may be worth a try...Thanks for the heads up..

One question though? How are you going to get the header out next time you need to?

That will definately make it harder to remove. My cheap fix is to take the tube to any exhaust shop and have them expand the tube "very" slightly.

 

I'm putting that on my list of things to try. I'm gonna do the t-bolt clamp tommorow and see. I guess you would get the headers out the same way people that get them welded. Undo the steering linkage.

 

Thanks for the heads up...I'm debating whether or not to pull mine out and weld it up. Downside is that I'd have to shiop it to JH and have them recoated .

I don't think pulling the header will be a big deal after you pull the steering linkage. Its REALLY easy to pull (linkage) anyway .

Damn, that sounds like a good idea.... I should try that... Here is a TTT to grab some more opinions.

 

I'm having a fun time tring to find Furnace Cement here in SE Texas.. hehe

 

Yeah, and the best thing is that it dries to a light gray finish, so it will almost match the ceramic coating on the headers.

 

Is it like that "Muffler Mender" stuff they sell in autoparts stores?

I tried that too on my slip fit leak. It worked better than anything else but it was too brittle and the vibrations eventually broke it apart.

No, I was looking at trying that stuff too, but the temp. rating was not high enough, and everyone that I talked to said that it would just burn/fall off. This stuff is actually a "cement" like material and it it's made specifically for sealing air and gas leaks through small crack and joints.

 

yea.. I found something this weekend too... it comes in strips and is like a putty... you stretch it around the pipe and re-assemble it.. it's fully removeable, but you must re-apply it afterwards. It's used for sealing up 2-stroke exhausts... but worked awesome on my leaking.

 

Another good exhaust sealent is 762, we use at work for our 2 stroke diesals and the manifolds will sometimes run red hot. You wanna talk vibration, these boats take a real beating. You can get this stuff at most any diesal shop.

 

Leadfoot - Before you applied the cement what color was it? I found some here in Dallas but it is black and I dont think that will look good on my coated headers

Thanks

Well, I went all over Beaumont tring to find that stuff, and every single place directed me to the concrete section heh. So I went out and got a t-bolt this morning. Wow, so that's how my car is supposed to sound w/o that #1 primary leak. heh.

 

I must be missing something... what is a t-bolt? I have macs and they use a slip fit design.
