yesterday I did a thorough cleaning including taking apart the exhaust T to vacuum inside the exhaust. I also swept the chimney liner with a brush. unfortunately there seems to be 2 silicone gaskets that broke that were part of the T. I tried my best to realign it and silicone the heck out of it.. but im still smelling smoke at he start up. I did the flashlight and it seems to be coming from all over the t. I smudged red high temp silicone everywhere and it did slow it down alittle but now it looks messy as hell. my question is should I just replace the whole exhaust t? or is it possible to replace the gaskets? If so where would I find these things? thanks
