That's what I thought too...
The strange thing is, there is plenty of evidence that there is oil being forced from the valve covers. There is always an accumulation inside the air filter box.
But I've never seen any accumulation in the catch can....
It's either travelling so fast as a mist, that it goes right through the can, or something came loose inside the can, or I need to add more steel wool as a baffle.
Gonna have to look into it come spring...
Lastly...find yourself a nice aluminium container...I think that a glass jar would be kinda sketchy under the hood.
