I noticed when I got my engine back up and running with a better mounting system that it was really loud. When I checked it out I found out exhaust was coming out the front end part of the engine in between the 2 mounting holes on the front part of the engine. I tried to seal it up with some some high temp sealant but it's not plugging the leak properly and it's quite loud. Is there a quick fix for this like liquid gasket ? I clearly need that gasket replaced but I don't know where to get my hands on one or how complicated it will be to put in a new gasket..
