Slight oil accumulation in air bridge and air horn - ZR-1 Net Registry Forums

The cam cover breather tubes are the most likely culprit, I would think, being that the vapor they carry enters into the intake tract right at the junction of the air horn to throttle body. Maybe deteriorated packing material in the recess of the cam cover, no longer trapping oil droplets?
