Hey gang. got me a problem, I have a tiller on the back and I was chewing up a friends garden patch and all of a sudden oil started to blow out of the breather plate down and under the carb. I guess it acts as a pvc does on a car, but how can it plug up? All there is in it is fiber filter type material. could it be commpresion geting into it some how? I was running fine and the next thing blowing oil, it runs out real good there is a type of louver on the plate that goes straight into the engin so it must be coming out of the crankcase, its got me bumfuzzeled for sure any help would be nice. this is an older JD. guessing about ten years old. but did not smoke or any thing.
