Hi-temp silicone question

[GeeZ]

I developed a leak on my Turbo Tom exhaust manifold. I need to take the easiest fix at this time. Will hi-temp silicone sealant do the job? It is only a small leak.

 

Thanks

Is the crack easily accessible without having to remove too many parts. If so and the car is drivable then take to to a place that does welding and have them put a quick weld on it. It would probibly be easier and quicker than waiting for glue to dry.

 

I don't think silicone will hold. If you have to use glue then try "JB Weld", if it is on the exhaust side then take a close look to see if JB weld will hold under that heat.

On an exhaust manifold, Hi temp silicone will not hold up! Just have someone weld it. If the crack is easilly accesible, it would be quick and easy, otherwise you would have to remove it.

I'm sorry that I did not make my problem clear. It is the gasket that is leaking. I think that the manifold or the head maybe warped so I thought instead of removing the head I would just put on the hi-temp silicone on the gasket. I thought maybe someone has done this. I remember at one time a company was advertising that you could assemble an entire engine using just their silicone sealant.

If it is just the gasket, Permatex Ultra Copper high temp silicone should do the job. You will have to remove the manifold though so you can get good coverage.
