352 Exhaust manifolds

[Guest]

Are there any vendors salling reproduced 352 exhaust manifolds? My studs came out on one side and aside from removing it I don't know how to fix it.

John Draxler at ThunderBird Ranch will definitely have a used set at a reasonable price.

Then there is also Bird Nest. They don't list it, but talk to Don. They can pull one from a doner car.

I had one come out and just Heli-coiled it. Or you could have someone tack weld the stud in place if the threads are no good. (I am assuming you are referring to the 2 studs that attach you to the rest of the exhaust system).

Exhaust leak

I have fixed the stud problem however there is a leak somewhere I can't detect. The manifold is not leaking and the flange is not leaking either however when I pull out from a stop light I hear something like a leak. If I have the hood up and the car is running if I give the car gas very rapidly you can hear something like a leak however I can't find it anyone ever have this problem?

I rebuilt my motor a couple years ago, got new gaskets and cleaned everything carefully. Put the system back together and had about 3 leaks (none at the head-manifold interface as I used copper gaskets).

I took it apart , used the Permatex copper gasket sealer for exhausts, and very carefully tightened things as evenly as possible (one nut a bit, then the other, back and forth) so there was no uneveness. No leaks since there in 5000 miles.

What might help you is to spray something on the running exhaust system so you can identify the location of the leaks before you work on it. Not sure what to use but other people reading this might know. But in any event, figuring out where the leak is can help alot - all of a sudden you say "oh ! NOW I know why it leaks!"

Some people use a pinch of flour until the exhaust leak shows up (in puffs). LOL!!! Hey it's flameproof!!

Manifold leak fixed

I had to replace the manifold gaskets, once we had the old gasket out you could see that the gasket failed at the inside webbing. I think the previous mechanic did not tighten the bolts well. We torqued the lower bolts to 28 could not get the upper bolts torqued however tightened as well as possible, also used a silicon exhaust sealer and let it set up for a hour or so in warm garage. It was nice to hear a 352 with no leak going home, pure ford power.

Originally these were metal to metal (no gskt to cyl head).Use copper gaskets. Fel-Pro makes them. I've had my exh/manifs resurfaced. I still have a slight leak (prob btwn the two middle cyls on the pass side). It's usually the right side. More heat from the EFE(Flapper valve).
