I'm sat here wondering what the small trench cut into the barrel housing is doing. It runs almost the entire length of the barrels but doesn't appear to have an exit just an entrance, shame the head is so crusty as it may be hiding the exit. The small mod and filler could be to deal with a leak from that trench, was going to say waterway but it could be something else, like an oil passage running next to the water jacket to keep the oil cooler, if there was a leakage between the 2 maybe the filler was there to stop it.Any idea what that feature is connected to?
