Blow By

Holy wow, and here I was worrying about the blow by in my 225... and it's nothing like what you guys are describing. Just some oil in the air cleaner after thousands of miles.

On another note, have you guys heard of the cap dance test? It's something diesel guys do to check for blow by. You loosen your oil filler cap and let it just sit there on the valve cover with the engine running. If the cap stays still, you don't have much blow by. If it dances around and or completely flies off the cover, you've got a lot of blow by.

Does this apply to gas cars too? My cap doesn't move at all, but I feel I still have blow by.
