I was thinking the same as Mike, but also check your fuel to see if it has gas in it. we had a guy dump some gas in a diesel and it was supporting and smoking pretty bad to the point of stalling out. Drained it out, new filter and all was fine. Worth checking, and a good sign will be the diesel on you fingers, it will dissipate instead of staying oily.
