I purchased a maxrev manifold from ben at import parts and i am having a problem. The tial wastegate i bought will not sit flush on the flange on the manifold. I already ruined the gasket that it comes with, so i made a new gasket from stainless steel sheet. Still having a monor exhaust leak problem. Is there any kind of liquid gasket sealent aid that i can use along with the gasket to help seal the leak, thats not gonna melt from the heat. As far as i know the only thing arounf is RED RTV that withstands 600 degrees, and i am not sure if that is enough. please help if you can. Thanks

 

some thing must be warped. call ben up. take some pics for us so we can see exactly what you are talking about

 

More than likely the W/G flange is slightly warped, you would need to get it re-planed (cheep) Otherwise you will keep killing those $3 gaskets and springing a leak. Lay the flange on a completely flat surface or use a leveller to check it's 'flatness'. If you suspect a part of the flange, use feeler gauges to identify potential warpage. I wouldn't really recommend using a band aid fix as a W/G leak is not the same as a simple exhaust leak. But if you must, copperseal might help.

 

yeah the flange may be warped, but in the meantime, you can try using copper spray on your gasket to see if that seals your leak.
