Let me start by saying sorry there is no photo. I have a small (if there is such a thing) oil leak on my 220. It is on the right hand side of the engine, just above the bearing plate. There is a circular disc about 1 1/2 in diameter that is weeping oil. If it were automotive, I would call it a freeze plug. The parts breakdown simply says "Plug" Anyway, it looks like the PO may have applied some sealer at one point (Reddish brown RVT???). I thought that was a crappy fix and then I was looking at rebuilt short-blocks and it looks like they come that way (with sealer, not with leaks) Anyone care to tell me what this part actually is and what it does AND if there is in fact a sealer that is the proper fix. Its only a small amount of oil, but I hate things that leak oil (no more old British cars for me) and worse yet, when the oil hits the airflow, it puts a fine coating on the cylinder head, which makes chaff start to collect more easily, and from what I have read, that's a no-no. So is this something I should worry about or just put my big-boy pants on and stop whining?
