Just did my head gasket because of the typical 1995 e320 leak that makes the cabin smell like an oil field. I am pretty sure it is a valve tick, tick, ticking away as opposed to an exhaust leak but I do need to yank out the stethoscope. I thought that was pretty strange acquiring a valve tick after reworking the head but I am hoping that there is some foreign object stuck somewhere where it should not be. My first thought is to add some Marvel Mystery Oil or Risoline (sp?) to the oil to see if I can move the potential foreign matter down to the oil sump so I it can be gone.

Thoughts , suggestions, guffaws?

Thanks,
