Both manifold gaskets are leaking on my 1049 bale wagon. We are able to get the bolts on the bottom of the manifold loose, but the bolts on the top are TIGHT. Have been spraying Kroil on them for days and a mechanic friend has tried an induction heater on them, but no luck yet. He isn't too keen on using a torch. Has anyone else run into this problem? We are thinking we may have to pull the engine, then if we do twist off some bolts, we can drill them out. Also, there were sheet metal covers over the manifold which I assume were there to keep dust and chaff off of the manifold and spark plug area. When we are using it, I take it to the shop every day and clean dust etc off with the air hose. But when we took the sheet metal covers off, there was still dust, chaff under them. We are thinking about leaving these sheet metal covers off so we can blow it out often and be sure to get it clean. Any ideas on these problems??
