What happens when too much oil runs out of breather?
The oil is checked on a dipstick after the engine has been rotated 90 degrees from it’s normal working stance to it’s storage stance (sort of on it’s face). Too much oil will just run out the filler hole when sitting this way. not allowing it to be over filled.
Where does the oil go in a lawn mower breather?
The problem I see is that the breather hole is lower than the return port to the engine body. There is a maze the oil must travel through and a metal filter that can pass oil into or out of the chamber on the path to reach the breather port leading to the carburetor.
What to do when oil comes out of valve cover breather?
You can expect lots of oil leaks and gasket failures. Make sure you have the PCV valve facing the correct direction. And, if that isn’t the problem, try a new valve. Your breather should act as the air “input”. If oil is coming out there, it is trying to act as the “output”.
What does it mean when your crankcase breather is blowing oil?
If your crankcase breather is passing oil, chances are that something’s wrong (Okay, we know something’s wrong, but don’t be too alarmed). Here are some things to look for while you’re searching for the source of the issue:

How long does it take to get oil out of lawn mower breather?
It both runs at high speed and at idle. It takes priming and choking both to get it started and then a minute to get it warmed up before you can remove the choke. After that, it runs pretty good, but the air filter just fills right back up with oil coming from the breather after only about 1/2 hour.
Why is oil coming out of my air cleaner?
Check out the article, Understanding Blowby in Motorcycle Engines, from MotorcycleCruiser.com. It explains why you had oil pumping out if your air cleaner assembly. The only other reason for this to happen can be from a broken oil pump or overfilling, as you mentioned. I have the same problem, and yes, my filter does need to be cleaned.
