njjeeper Posted February 12, 2016 Share Posted February 12, 2016 The 2 pipes from the exhaust manifold outlet that go to the elbow that bolts to the inside hull on my ferret leak at the joints. It seems to just be 2 pipes with flared ends that fit into the elbow and manifold. Is there a gasket or sealant or something that helps this system seal?

robin craig Posted February 12, 2016 Share Posted February 12, 2016 Great question, it is a common one asked by newcomers to the Ferret world. The basic concept that I am led to understand by those who told me is that the two tubes are supposed to expand and make a tight fit but still allow for hull flexing. Frankly it is old technology if you ask me and in today's world if it were designed all over again I think you would find a stainless flex piece in it's place. I have seen and experienced mechanics refusing to issue a safety inspection certificate because of the leak and I have always argued that the flow of air is through the vehicle out of the back and the engine decks are not sealed so the idea of being overcome by exhaust fumes is not one that I see as very credible. I think Ferrets are long enough in the tooth now that those tubes have lost their ability to fit properly and I have seen many attempts to fix them that do not work. I think it is a question of returning things to their original fit tolerances or a work around. I am no expert and don't claim to know everything, it is just my view. Others will be along soon to offer their 2 cents worth Robin Quote Link to comment Share on other sites More sharing options...
Starfire Posted February 12, 2016 Share Posted February 12, 2016 I thought mine were missing some gaskets too. They are super-loose though... Cheers, Terry Quote Link to comment Share on other sites More sharing options...

njjeeper Posted February 12, 2016 Author Share Posted February 12, 2016 Thanks all! At least I know I'm not missing pieces. Since I didn't take any of the vehicle apart, I never know whats missing from the bins as I reassemble Quote Link to comment Share on other sites More sharing options...

DFC1943Fl.Lt. Posted February 12, 2016 Share Posted February 12, 2016 I will most likely have the same issue with mine now that I've put the engine back. Being in the building trade, I build a lot of fire places and use fire rope for a gasket between the cast iron fire surround and the fire back. This comes in a variety of thicknesses. I will be trying this out with some fire cement and if it works OK will let all know. Quote Link to comment Share on other sites More sharing options...
Starfire Posted February 13, 2016 Share Posted February 13, 2016 I'm tempted to take it in to an exhaust place and get a couple of flex pipes fitted. Quote Link to comment Share on other sites More sharing options...
rob233 Posted February 13, 2016 Share Posted February 13, 2016 ALL parts are available, 2 pipes,1 elbow,and gaskets,one per side,little bit of jointing compound,keep it original. the elbow can crack,make sure you clean both sides of the hull,before refitting gaskets,nothing worse than finding you have a small blow.
