New PCV valve -Presence of engine oil

[boobird]

Found 1 or 2 drops of oil in the Drivers side PCV hose coming out of the valve. Replaced the pcv valve last month.

Any ideas why? Cause for concern?

Normal.

The vacuum from intake is sucking oil vapors. This keeps pressure from building in crankcase.

BTW: If 98-02 replace the grommet PCV valve fits into. Also replace either of the 2 hoses if hard and cracking at end.
