I have a Kubota t2380 lawn tractor. I purchased it new in 2010. It had began to smoke a little occasionally from the exhaust and the oil smelled like gas. I was told the float was probably stuck but would be OK if I shut gas off when not in use. I did but it recently got worse and it had began to use oil but i checked it prior to use and kept it full
It began smoking a lot and wasn't just from the exhaust and I thought I could of spilled oil and it was burning off so I took off shields and cleaned up quite a bit of oil under muffler and from shields. Well when cleaning up oil I found a nut under motor on frame. Upon closer examination I saw where the nut had come off the manifold and was actually missing the other as well. I replaced both nuts and it did stop all the smoking but next time I Mowed when I checked oil it was extremely low. I filled and mowed for an hour or so elwith no problems. I left mower sit overnight and when I checked oil the next day before mowing it was very low again. Upon inspection I found the oil to be leaking around manifold and 1 of the nuts loose. Well after that I saw a hole in valve cover with rod sticking out of it. Is the motor done? If not will repairs be expensive? I appreciate any input anyone may have. Why did this I happen?
