JBA header owners please read!
I just got my truck back from the exhaust shop today as it was almost 90 here yesterday so I didnt want to be doing the header work in that heat. I picked it up today 207 dollars later, and I have a F*CKING leaking on the passenger side. Has anyone else had this problem? I thought JBA was supposed to be the best for the Ranger, I am feeling shafted, if I knew it would sound like a Model T when I hit the gas I would have left my stock manifolds on there. Now I have a truck with 23K on it and it sounds like it has 400K, not happy.

I thought the same thing at first, they are all friends from when I worked in the Auto business, I trust them with all my exhaust work and have had about 8 vehicles of mine go through them this is the only one that I have had a problem with. I AM PISSED
Well if your sure its not the shop, I'd say contact the place you bough them from and tell them. And since you had them professionally installed they can't say that you F'ed them up.
Could have just gotten one bad set. It does happen from time to time w/anything.

I know that they worked, I got them from Bob, as all of you know he is a real stand up guy. I have contacted Brad the JBA rep on here to try and get some answers but so far no reply.
Well if they worked for Bob then theres something wrong with your truck or there installed wrong....
Could've been shipping damage. Even if the 'gasket' doesn't look bent, the slightest bend could make it leak. Sorry about your luck. I don't think JBA is the one to blame since they've already been tested to work.

If it were shipping damage I would assume that they would both be crap, because they are packaged one on top of the other and I had them sitting on my dash the entire time after I bought them.
Thanks I have read this as well. I asked the guys at the shop if they did this and they stated yes. Even took the passenger side off again once because they though maybe it somehow blew the gasket
Yeah I am 89% sure. I am going to take it apart myself tonight I guess and see what I can find or fix myself.
JBA's are HEADERS! HEADERS have always been known to rattle loose the flange bolts at the head. I got really really used to it. Gasket plays a role too.
What kind of gaskets come with the JBA's?
You're issue could be as little as improper torquing/tightening of the Y pipe at the header. Mine has that little tick issue because I didn't properly tighten those nuts...and I got the stock manifolds.

I suggest finding where your leak is coming from. There, you'll be able to pinpoint whats wrong. Might be as little as them not being able to tighten those last bolts on the passenger side due to clearence issues with the heater box or whatever.
Those same headers were on my 4.0L for about 2 years with no leaks whatsoever. In fact, I was amazed at how quiet they were. Tube headers often have a ticking through them even when the gaskets are perfect but the JBA tubing is so thick that they are almost as quiet as the factory iron manifolds. I used stock Ford stainless gaskets and I believe that Chris's installer used the same. I say recheck the fasteners - some of them are difficult to get to.

The headers should do a better job than stock as far as sealing. They have a raised area around the ports that "bite" into the cylinder head. The stock manifold is a large flat area.
Expansion/contraction will cause a leak. I want to say retorquing is recommended at 10,000 miles. Don't quote me on that though.

Make sure they installed the gaskets correct. My roomate just put a F2 header on his 2007 Focus ZX3 and had a nasty leak after the shop installed it, he took it back and they just 're-seated' the gasket. It is much quieter now and has a subtle growl to it.
