Oily air filter
 

What's going on when the air filter seems damp with oil? I replaced a while back the 1990 Accord air filter and the old one seemed like it was moistened with oil, it seemed that the oil came not from the outside (bottom) but from the engine (top). Why would this happen? the intake hose seems dry on the inside. The guy that changed the filter (at the oil change in the service station) said that it could be the valve seals, is this true? What else could it be? I checked it now(after a couple of thousand miles) and it is dry, dirty but dry:crazy:

i dont know. unless its just water.

i have the same problem with my 92 accord, and yeah, the valve seals seem to be the culprit

The funny part is that everything around the filter, hoses etc are dry. Is not that the filter was soaking in oil but it had some oil residue.
I changed the oil seals and the new filter seems dry, so I'll just keep checking to see if it stays dry in a couple of miles.
