Snowblower engine blowing oil !

My Tecumseh engine (10.5 hp) started blowing oil out of vent tube on carb side of engine. Only happens during hard use such as the 24-30 inch snow that we just received. Any similar problems or solutions ?

Common issues are too full of oil, (may have been contaminated w/ fuel),breather itself defective or return plugged, rpms too high, external leak such as missing dipstick seal, or simply excessive crankcase pressure from a worn engine. If you are really horsing the machine and /or it is being tipped back a lot- just cover your bases best you can and it should be fine.

Changed oil this morning to make sure I had proper amount, 28 oz on this one. Also, if I stop the engine to check the oil level, there won't be any on the dipstick at first. After it sits for a while, it will then show on stick. Seems like an oil return problem. Machine is a Husqvarna and is only a couple yrs. old. Not that many hours at all. Thanks for the response.

When an engine is running, it splashes the oil all around inside the crank-case. And after the oil heats up, it goes everywhere inside the crankcase. After it cools down a bit, and sets quietly, and cools off, the oil will thicken and you will be able to get a reading.
I have seen a machine that the owner did the oil check too soon, with the oil being hot from running. He did the dip-stick check, and since the oil was hot and thin and splashed all around inside the engine, he dumped in a lot of oil! When it cooled down, it had too much oil in it, and clogged everything up!

Do you think the oil return hole under the valve cover is blocked by a broken piece of gasket or carbon?
