[Shop-talk] oil vent mess

[Benjamin Zwissler]

I'd first check that your PCV valve is working.  Sounds like your crankcase
is venting out the filter when it should be sucking fresh air in there.  If
your PCV valve is stuck closed (or hose collapsed or something otherwise
blocking PCV flow) that would cause the crankcase fumes to find another way
out - through the filter.

Other option is you've got excessive blow by that's overwhelming the PCV
system.  That would seem unlikely on an engine with 5000 miles, unless
you've got stuck piston rings or something else major wrong causing lots of
combustion gas to get in the crankcase.
