Although my car is not a ram car, my 62 Sport with the H option, had exhaust leak issues as well. What worked for me was to remove the exhaust manifolds, clean and reinstall them with a Mr Gasket header gasket. The trick was to re-tighten the bolts on a regular basis after the install. Warm the engine up initally, let it get cold and then re-torque the bolts. You'll be surprised at much these things loosen up. I had to re-torque them several times before the remained tight. I've since put about 2K on these gaskets and all is good. Charlie in Ottawa On Feb 29, 2012, News4ge@xxxxxxx wrote: Have you tried compressable metal gaskets? I've heard that they're available for Chevy motors, so maybe Mopars can have them, too! I'll try to find out if they do exist. I hope I can change them without removing the intakes.

Can we assume that there has been no warping of the block? Not much sense in milling the manifolds if the surfaces to which they are to mate are not true as well. I have a similar problem with my G and while I certainly don't have headers on it, I keep blowing manifold gaskets one after the other. Maybe I should consider having them milled to see what the result might be. Pete Fitch In a message dated 2/28/2012 9:48:35 P.M.

Hi, I remember some discussion about excessive heat coming out of the exhaust ports and blowing header gaskets. Has this happened to you? Have you found a relatively easy way to fix it? I REALLY don't want to remove the intakes again. Is it possible to unfasten all the nuts and bolts and have enough wiggle room to slip on a new gasket, or even to use a sealer or liquid gasket? Is the temp. coming out of an exhaust port too much for a sealer? Didn't someone say that some of these cars didn't even get header gaskets from the factory? I hope someone can help answer this. The noise and fumes are getting tiresome! Thanks, George Clineman [Non-text portions of this message have been removed] No virus found in this message.
