Oil in intake/AFM

[Andy348]

Just found some drops of oil under my car today. It seemed to come from the PS pump, but upon further inspection it seems to be coming through the intake manifold to the AFM/air filter and dripping down.

I recently did a head gasket change so I figure I fudged up the o-rings for the bitch tube, but what else could be the cause?

edit: M20B25 btw

If the engine has significant mileage on it and/or the intake valve seals are old there will be oil in the intake. But enough to drip like that is probably from some other cause.

I just finished a 1200km road trip, beforehand I cleaned the AFM so all of this build up is from then on.

I'm going to smoke test the engine tomorrow and hopefully find the culprit.
