damn exhaust leak

jaidedeye · Dec 22, 2004

i installed my new ford motorsorts ceramic headers a while back. i cannot get rid of a leak on the collector to save my life....is there anything i can put around the collector ball to get it to seal?

If you can get it to seal the first time... then you have a gift.

All i can recommend is loosen it and bring the flange down evenly using the bolts. If it gets crooked sideways it can cause a leak. I don't know of anything other than that heat wrap stuff that you can put on that.

you can probably take it to an exhaust shop and have them weld up the leak.

Try these...that number on the bag should be good at most parts stores...its a recent p/n....

Undo the collector, slide 1 in and snug it up...cured mine...been using em for couple years....

As you can see from my flanges, they been reefed on to help cure it before i tried the gaskets...there only .070 thick, have Alum inner wrapped around the gasket..they last pretty decent...

Make sure your motormounts are good. A shot motormount can cause tons of exhaust leaks when the motor twists and as a result, twists the exhaust all over.

I just went through the same crap with my ceramic shorties. My flange on my H-Pipe was bending when i was torqing it down. I took the passeger side h-pipe off and beat the flange with a hammer to straighten it out. I also put a small bead of silicone "high temp" gasket maker stuff, around the edge of the collector, and it worked for me. Good luck man, i know how you feel, its a pain in the butt

Tightening down evely has always done it for me. You may even want to count turns with your ratchet -- 1/2 turn here, 1/2 turn there, to get them as even as possible. When they start to snug down you'll be ok, but it's the initial tightening that will determing if they snug down evenly or not. Always worked for me no matter which heads I've used (including JetHot FRPP).

So the high temp gasket maker doesnt burn off?

I think that high temp stuff is good to 500 Fahrenheit. I wonder how hot the collector gets?

I have found I have to loosen all the hangers to get enough slack to "average" out the mismatch. I fought this on my last install. Plus I had several header bolts backing out every couple of days. Stage 8 bolts fixed that!

wakey, wakey

i went to my local napa to look for these collectors. i told him the part number. 31540. he put it in the computer and nothing came up.

he asked me to find out what brand they are.
