OK, well I replied to your other thread, but it sounds like you have this figured out…Does that plug thread into just the cooling passage, or does it go directly into the crankcase? I guess I would just goop up that plug real good and reinstall it, unless it goes into the crankcase as well as the cooling passage.
Like Frank says, powerhead disassembly at this point is a best guess judgement call. It is amazing how strange exhaust pulses can draw water back into the powerhead. At this point, the powerhead, exhaust cover, and cylinder head are off, won’t take much more work to split the crankcase and pop the rod caps. There are no needle bearings to fuss with, making powerhead work pretty simple. If the rods/crank are OK, then it won’t take much more work to do the quick hone job, and replace the rings. I guess it all comes down to how much you like this engine, and how much you plan to use it.
