I have a Kohler Magnum 20hp. I have oil coming through the breather tube and into my carb. I wasn't sure if it was blow by from the valves. Any help would be greatfull.

Thanks,
Dave

Have you checked the oil level? If it is too high it may cause your problems, else it may be a valve problem or something, hopefully it is as simple as your oil level. Good Luck

Also see if the oil smells like fuel, A flooding carb can fill the crankcase.

If the oil is fine there is a rubber umbrella valve inside the breather assembly that could be hard or deteriorated, This could cause excessive oil through the breather hose.....
