Hello, I recently bought a 2008 Bobcat S250. It blows some white smoke at startup and idle, but once it is warmed up and at higher rpm it runs great and doesn't smoke. The other day I started it, let it idle to warm up and it just quit. Tried to restart and it didn't even try to catch. Checked the fuel filter and it was full of water so I'm assuming the tank probably needs to be flushed. I removed the fuel bulb, put it in a container with fresh diesel and was able to get it started without to much fuss. BUT while it was running I noticed a good amount of oil coming from the turbo exhaust gasket (I don't remember seeing this before, but judging by the amount of oil that is on the back of the engine it has probably been an issue for a bit). I removed to turbo intake hose to take a look at the turbo and there is what seems like a lot of side to side play, but not back and forth as far as I can tell. I did find it interesting that the intake hose's hose clamp was just sitting there loose, so I'm assuming the previous owner had been in there.
I believe there are some oil return lines from the turbo that I should investigate to make sure they aren't plugged, but I'm guessing I'm looking at a new turbo since so much oil is coming through the exhaust... would that explain the smoke at idle?
