Exhaust Manifold Leak
Well I was hoping it was a donut gasket leaking but I found it is the Manifold gasket leaking I think I will wait until this winter to fix,but is there any suggestions on the best way to do this so I won't bust any bolts off in the heads, and what will be the best gaskets to use when I put it back together

Hey Bob,
Had the same problem on Christine. Sprayed penetrating oil (none flammable) on bolts, drive her, bring her home and spray some more on there. I done this for several days before trying to remove bolts. Got new manifold gaskets and talk with older gentleman that has a lot of experience with old cars. He told me make sure manifold and heads are plane. Since they were run hot and leaking there was a chance they were warped. I thought about it for a while and took them apart, took framing square and ran across them to check to see if the were plane. They were. I got new bolts and lock washers. Install gasket and snug bolts. Ran her till she got hot and let her cool off and retighten bolts. Left her sit for a few days and done it again. So far no leaks, only thing is she is to quite now!!!

Exhaust Manifold Leak
The problem of exhaust manifold leaks has been talked about so much in the past. I did a quick search and found this. Here are some suggestions as to what to buy in the way of good gaskets..

I've used copper gaskets on any 352's and 390's I've owned and they seem to work well.

Several places carry them:
JC Whitney, Summit, etc.

About $25 a pair if I remember correctly.

I don't use gaskets - just that clay type goo that bakes hard.

Dan Leavens 08-05-2009 05:27 PM

I would agree with Casey that copper gaskets work out just fine.

CRC MANISEAL is what I use for all exhaust gaskets/seals.

:mad::mad::mad: Well HECK
I have been soaking all the bolts for days and then I heated each one with a Tourch got it good and hot all the bolts out but the last one and it twisted off. So now I must take the Head off and drill it out it is the top front and there is no room to drill it out on the car,well now I can see what the heads look like.

Hey Bob,
Do you have or do you know someone who might have a angle drill?
