It's a moot point now. The motor is done and I don't have the time or the desire to rebuild it; on my own or have someone do it. I'm basing my thoughts on the fact that for as long as I've owned it, I've had to add oil at least every other time out to keep the remote reservoir above half, and the two days out this year I've made runs of 15, and 25 minutes (both ways) respectively and seemingly haven't used any notable amount.

I may very well have a crack somewhere, or a warped head and I may have (had) water issues, but the lack of oil use was the first thing I noticed when I got home from the incident.
