Spark plugs fouled up repeatedly

Hi guys. My spark plugs are repeatedly getting fouled up bad about every 150 miles. And it seems to be all of them, not just certain cylinders or anything. Any idea what the issue could be? I keep having to pull the plugs and clean them, it's getting to be a hassle

Re: Spark plugs fouled up repeatedly

are they covered in oil or gas? could be a few different things, but that will definitely narrow things down.

most common reason would be bad valve stem seals or worn valve guides
