took the hose off the underside of the upper intake and a decent amount of oil came out. by decent i mean more than a couple drops. actual amount was probably not much more than few drops. lets say approximately at least an eyedropper full?
that line comes from the PCV valve. the way i understand it is the upper intake sucks fumes out of the crankcase and into the intake to be burned in the combustion chambers.
i may be incorrect on this.
im not sure what those other lines are for (marked L and K). i believe they are vacuum as well, but not sure at the moment.

regardless, if i am correct on the way the PCV to intake line works, i dont think there should be any oil getting sucked into the intake, even though i understand there is oil in the crankcase. maybe im wrong. maybe oil is splashing around in the crankcase and a drop or two gets sucked in every once in a while?


long story short, should there be oil in the line that goes to the port i circled?

thanks in advance

yes there could be....does the pcv valve rattle if you shake it ??? if yes its good, if no...thats prob why you have oil in there. the upper almost needs to come off to replace it and peeps just wont do that
and yes... K , L, and N are all VAC

i seem to recall it rattled.

so the oil in there is no problem?

A lot of higher performance engines today need an oil catch can between the PCV valve and the intake.
The catch can removes the oil from the air being sucked in. Some engines suck a LOT.
Steeda makes one that looks and performs well, it is around $100.
The sucked in oil makes a mess out of the insides of the intake and attached components but also will greatly reduce the lifespan of your spark plugs.

One of those lines is for the fuel vapor return. Not all are vacuum.
