I have a John Deere La145 Mower. It is 9 years old but only had 130 hrs. I changed air, oil, fuel filter today and began cleaning engine with engine degreaser. I also spilt some oil on frame when I took off oil filter. When I went to crank it up, I didn’t notice smoke at first but after running it in shop where I was working on it, I noticed smoke in the air. It appears it is coming from lower area of lawn mower. Smoke is not steady, sort of in puffs. When I cranked engine, it was running good. I checked air filter. No sign of oil. Everything looked fine. Oil level is not quite at full mark.

  1. If I didn’t get all of the engine degreaser dried off, could that have caused smoke? I had sprayed it all in engine area.
  • If you are seeing “puffs” of smoke the engine is burning oil. Surface oil might get hot enough to smoke, but your not going to be seeing “puffs”. – Tyson Dec 28 '17 at 1:55
  • Ok. I am not sure if I described it best as puffs. It was producing a little smoke but it was not constant amount of smokes. It would be produce a little smoke, stop, and start again. – georgia-guy Dec 28 '17 at 2:19
  • How does the engine run? Does your fresh oil still look fresh on the dipstick? Can you clean the oil off and it stops smoking? – Tyson Dec 28 '17 at 2:21
  • Engine ran well. Sounded like normal. I didn't check oil after it smoked tonight. I was moving it from shop to another area where I stored it for the night. I ran it less than 3 or 4 minutes. – georgia-guy Dec 28 '17 at 2:24
  • Oil left on an engine surface might smoke but won’t last and can be cleaned off. If gas leaked into the oil the oil will turn white or grey and may be slightly bubbly or foamy. White smoke is oil burning tho, gotta understand where it's coming from and how much. – Tyson Dec 28 '17 at 2:29
