Air Filter Question

[cocothecat]

So I serviced the car today and noticed some oil on the air filter when I was replacing with a new one. Is this something to be worried about or not?

Was also small traces around the plastic housing, where the small pipe leads into it. I can get a photo later (its a small pipe that leads to the engine i think and no jubilee clip holds it in place)

Yes,,you must get the blocker for the camshaft sensor right on the front of the engine near the top,pull the plug off and see if it is oily
