Will JB Weld fix this?
 

I broke an A/C line a while back when moving the A/C condenser forward enough to get my IC behind it for stealth. It broke the little tiny ass fitting that goes into the accumulator. Well, i got a new end and had it welded on. Fixed it.. I thought. Damn thing still leaks a spec right at the connection. I serviced the A/C properly with a vac pump and manifold when I changed that line. The system is still has freon, but it's low. I added about 4 oz to it a while back and after 3 months it's leaked those 4 oz back out. Had to use the A/C this weekend and it reminded me this needs fixing. A/C has to be right. :y

Think some JB will fix this? I can scratch it up good, clean it with mineral spirits, etc. But think the JB will actually seal it up? It leaks just enough to make it oily and dirt sticks around the oily area as pictured. JB's never failed me before, but this line gets hot, sees vibration, ~240PSIG, etc.

Also I'm thinking the original JB weld but I'll have to do something so it won't drip off. Need a form to hold it till it sets. :8

get a product called pc7. thicker, stronger, and is lightly fibered like tigerhair. MUCH more workable over jb weld too. i use it exclusively over jb weld, plus it's cheaper

Re: Will JB Weld fix this?
 

Where can I get this? I gotta order it online or pickup at Lowes or wally world? Google shows Ace carries it but no Ace hardware around here.

Re: Will JB Weld fix this?
 

hardware store or national supply store (lowes/HD, maybe walmart)

Re: Will JB Weld fix this?
 

We have a Souther Pipe and Supply. They might have it. I'll check wally-world tomorrow. I got plenty of JB though so I might just use that if it will work.

Re: Will JB Weld fix this?
 

JB weld is fine. If it drips off just let it cure for a little longer, maybe 30 minutes to an hour before applying it.

I dont think anything can fix a miata.

Re: Will JB Weld fix this?
 

! I really used to hate miatas until i've seen them properly modified. Now, they're not so bad.


JB weld can fix anything....except cracked timing covers on fail caviler z24's.

try a new o-ring first. make sure its one of the green high temp ones. i used to do custom a/c installs on airplanes, we had to deal with ---- like that on a regular basis. if the o-ring doesnt do it, then just have it rewelded

intercooler behind the condensor = fail

I did this and it helped a lot. http://i231.photobucket.com/albums/e...5/100_1875.jpg

Re: Will JB Weld fix this?
 

Yeah. That would be better, but... I don't have my pump and manifold up here at college. So I'm looking for a cheap fix till this summer. And if it works well I won't fix what's not broke. Going to look for the pc7 stuff and if I don't find any, I'm JB welding it.

Re: Will JB Weld fix this?
 

Take it back >:D

Re: Will JB Weld fix this?
 

How does one crack a timing cover. Was it the 2.4?

Re: Will JB Weld fix this?
 

Nice interheater. Gotta keep those IAT's high you know. Dangerous horsepower is dangerous. :6

Re: Will JB Weld fix this?
 

Agreed. It's for stealth, not performance. What could possibly feel worse than getting your ass handed to you by a seemingly stock miata?

AIT's are 5-10*F hotter than ambient in cruise, rising 2-6*F in full boost. With A/C on, add 30*F. I ran a mustang GT a few days ago with the A/C on, shifting at 5K. Still waxed his ass and stayed cool doing it.

Lowes don't have the PC7 stuff. Didn't check wally world.

Re: Will JB Weld fix this?
 

I JB welded it a little while ago. Gonna let it setup and tomorrow I'll sand and add some more cause a lot of it dripped off. Hope this works. :8 Checked wal-mart and they didn't have the PC7 stuff either. JB's never let me down, so I have faith.

its been holding the tranny from leaking on my brothers 98lx just fine for 2 years now, you should be fine

Re: Will JB Weld fix this?
 

I let it cure 20 minutes, wasn't enough... I'll give it an hour next time or more.
