Hello Everyone, Hoping someone could help me on this issue!
I am at wits end with my Toro Recycler mower with a Kohler XT-675 engine on it. Currently this engine will spit oil (with velocity) out the crankcase breather which vents into the air filter box. Usually it puts enough oil in the air filter to fill the carburator and stall the engine. This ends up with either requiring a carb clean or a few week sit for most of it to drain back out and allow to start again. I have verified multiple times that oil level is within specs. For someone to visualize how much force the oil is being pushed with, you can imagine without the air filter on, the oil is propelled out the air box 1-2 feet away from the mower.
One thing I read online is the float in the carb may be stuck open thus causing the engine to flood and the oil to thin out raising the level higher and thus making it come out the breather tube on the crankcase. I have rebuilt the carb and it is still having oil blow out the crankcase breath. One thing to note is the oil is not thin and does not have a strong smell of gas either.
I have rebuilt the breather with a new spring and disc under the recoil starter of the mower with the assumption it was staying open allowing oil past it. This also did not fix it.
Other things I have done to try and remedy this is done a valve job. Both the intake and exhaust where about 0.002" out of spec but are within spec now. Still, none of these remedies have helped.
Next things would be to check if the clearance between the cylinder wall and piston rings is within spec, but I have not had a chance to tear it down that far yet.
Details of the engine are : Spec No PH-XT675-2011 serial number 4210428758
Does anyone have any ideas or known fixes for this issue?
Thanks in advance to everyone who tries to help!!!!
