Crazy oil leak under air filter, non-turbo
I have looked at tons of threads about this, but they all seem to deal with turbo models.
There is a lot of oil leaking from under the air filter, can someone please point me in the correct direction for info on this?

Is it just the oil seperator leaking? Perhaps a bad o-ring on it or the grommet where it goes down into the oil pan is bad?

there is a black hose that goes underneath the air filter.. its a breather hose if im not mistaken.. check if it may have been dislodged.. had than happen to my 300 NA... i simply placed it back.

put screw down hose clamps on that hose and replace the large rubber seal from the housing to the manifold, that stopped the leaks on mine.

Sounds like it's leaking from the breather hose, you probally need to replace the rubber elbows connecting it to the manifold. Mine had a very bad leak before I replaced them, now it's just a minor leak...
