Sorry if this has been covered elsewhere but I couldn't find anything relevant in the search. I have an 873G with a Deutz oil cooled engine. I can't remember the year but it was the last one for 873's. It has 400 hrs on it and I use it around my house for mowing, snow removal, etc. Last evening I was turning over my wife's garden when I noticed black smoking coming out of the engine compartment. I shut the engine off, got out and felt the rear door - it was too hot to touch. It turns out that the left side of my muffler had rusted out so the exhaust was emptying into the engine compartment. I hit the back with a hose and once it cooled enough, got the door open. Oil was everywhere. It appeared to be shooting out near the left hand side where the valve cover gasket is - under where the hole in the muffler is located. I put a picture up of where I think it was coming out at www.idjsolutions.com/bobcat. I had no warning lights / buzzers and the machine was working like a champ when I noticed the smoke. I'm hoping I can get out with a new muffler and maybe valve cover gasket but thought I'd ask the pro's here to see what you think. My nearest Bobcat dealer isn't very near and I'd rather not spend a fortune having them come get it if I can fix it myself. Any help would be really appreciated!
