My JD 757 zero mower blows oil out of the dipstick hole .Tried a new dipstick,its still coming out and getting blown by the fan on the hot muffler?????????

I know this is an old thread but that's usually a sign of a blown head gasket.
What happens is compression from the cylinder is leaking into the crankcase building up pressure, that's why it blows out the dipstick tube when it's running.

By now we should have an answer, what was the problem?

Does it have a double "reed" type crankcase vent ???

If so, one or both may be just crudded up or broken.
