Engine smoking
Hi, I'm trying to help my brother with a problem he's having with his FE290 in his Club Car DS.
It is burning oil, he keeps having to add oil. There doesn't appear to be any visible leaks. If I'm following him on the road, I can smell burnt oil in the exhaust. If he stops at a corner, when he accelerates there's a big cloud of white smoke from the muffler. I've checked the compression and it's about 170 psi. It held 170 psi for 15 minutes. Any ideas on what I can check next? Thanks |

Over the years I've seen many lawnmower/small air cooled engines trashed because of this. Generally when it happens it will be a sudden occurrence and not a gradual thing like the rings slowly wearing out. how it works is when the piston goes down the valve opens and air should be pushed out of that valve/hose and then when the piston goes back up it won't let air flow, hence the slight vacuum. When you hold a strip of paper over the hose with the engine running it should be pretty much only being pushed outward, if its flapping back and forward then check that one way check valve and clean it to correct the problem. What tips me off to this being the problem is the high compression reading. meaning the rings are good. |

Re: Engine smoking
Compression rings can still be good but worn oil scrapper ring will cause smoking and oil burning issue

Re: Engine smoking
From what I’ve read and have learned, the oil ring may be bad on the piston.
My 99 has great compression, runs great etc...But... I can see puffs of smoke and smell it out the exhaust and it consumes oil. |
