Muffler cement

[rrlund]

I know muffler cement works for exhaust pipes. I bought a tube of it this spring and used it on the exhaust pipe on my truck, it's still holding up. Has anybody ever used it on a manifold gasket that's not in very good shape?

I had to take the manifold off my Oliver 500 gas with the David Brown Crop Master engine from the 50s. It's a single piece gasket that runs the whole length for the intake and exhaust. It's good on the intake and on the exhaust on numbers one and four. Numbers two and three kind of crumbled a little bit on the top. I've searched for a new gasket and the only one I can find that I even THINK MIGHT be the right one is in the UK. I wonder if I can just put some muffler cement on the part of it that's not great. If it was the intake, silicone would fix it up for sure, but that's not going to work for the exhaust.

I would try it, what have you got to lose other than a bit of gasket cement, it sounds like the gasket is already on its way out.

I have used it before on IH gas engines with the same type of gasket for ( intake and exhaust) as one gasket. Only put it on the exhaust ports. Have had good results.

I needed to make an odd manifold gasket once and bought a piece of gasket material from a hit and miss supplier. Interesting to cut to shape with the wire inside but it worked .

I just didn't want to unintentionally weld the manifold to the head.

From using it in similar applications I have been able to clean if off the metal parts it was against.

Ya, I'm hoping I can just knock some flakes off and still have enough old gasket material left so it's making contact with that and not with bare metal.

I would not worry about it touching the metal. Any I used is just more of a hardening filler than a cement. I have cleaned off pipes and mufflers with a wire brush or scraping.
