Is there oil on the black plastic ignition rail that covers all the plugs?
Is there oil where the black intake pipes meet the intake mainfold?
It is not very likely a head gasket since this engine uses very good
sealant for the head to block contact area.
Is the ABC fluid reservoir low? this is also very common to leak onto
exhaust. See dealer for recall/service campaign.
