Did a sprint round on Sunday and on my 3rd run smoke started pissing out from under the bonnet. i had a look to find oil oll over the left side of the engine

Upon closer inspection i found it seemed have spewed out of the K&N breather filter near the catch can.

The catch can is nowhere near full and the engine lost about 300ml of oil through the breather. I didnt finish my Sprint but drove the car home and it all seems fine, hasnt blown any more oil out. Also i checked my oil before i went out to the sprint and it was just under full on the dip stick and definatly not over the F mark.

Any ideas WTF is going on here?
