Why would an engine flood the cylinders with Oil? and how do I fix it?

I have a 4 cyl. (V4) air cooled engine in a bobcat skid loader that when started, floods the cylinders with oil, backfires black smoke and dies. I then can't start it again until I drain or blow out the oil from the cylinders. It just started doing this, but it has always burned a lot of oil, it's an old engine.





It's a VERY simple engine to work on, so any common fixes would be appreciated. As of now I can't run it for more then a couple minutes before it dies.Why would an engine flood the cylinders with Oil? and how do I fix it?
Sounds like the engine needs a rebuild. The piston rings and value seals need to be replaced.Why would an engine flood the cylinders with Oil? and how do I fix it?
yeah it sounds like the rings to me as well , have you ever gotten it hot? if so probably scalded the rings and cylinders.. if not been hot just wore out that happens sometimes ,, if just wore out you may get by with just putting oversized rings in it,,, if its wore enough ,, if its not wore enough you'll have to have the block bored out to the next size ring 10 over 20 over is most common,, but if you do tear into it check your bearings while you got it appart may need complete rebuild.


i know its bad news but it happens
You probably have leaking valve seals in your head you can have the head check maybe just put a band aid on it by replacing the seals. It is possible that the rings are bad but unless you noticed a big difference in HP it is probably not that.





I would take it to a reputable Diesel shop that has the capability of repairing heads in house.





It sounds like you don't want to put a ton of money into this machine so i would recommend finding a used engine instead of rebuilding yours.

Needs to be rebuilt the rings have gone and the cylinder needs to be rebored
I had a Tempo that did that too. It was the seals. I ended up getting rid of it because it was to much work and and old car.
definatly need new rings and new gaskets all around.
