Same problem...decent blowby...no plugged tubes

273K miles or thereabouts.

I have the old breather tube but still...this air filter is sad looking...it was new when I got the car and other than a crapload of oil, it looks clean. Maybe I will try to seal all the "in air filter" parts except for the out tube that goes down the intake twoards the turbo. (all of thiis stuff is inside my air filter)

Hm.
