Interesting. I'd not like it to happen to me(G). My turbo must still be pretty good, I'm glad for that. I wonder how a diesel that had that bad of blowby could even start in the first place, compression being the critical component that it is. Of course one really bad cylinder with crankcase ventilation supplying the oil might do it too. My only exposure to this type of effect was actually with gas engines that have gotten hot, with carboned up cylinders. Sticking it in gear works great if you have a stick shift(G).
I am not sure I understand your biogas gen. sets.? run down to 5% diesel? I have wondered about using the injection method for other fuels. I wonder could you do it with gases by compressing them to liquid form first?. Seems to me the effect might be to freeze your cylinder(G). In a pinch I wonder if gas mixed with two stroke oil (extra on the oil) and a slightly retarded injection pump would work in a diesel? When my van was fairly new, a station attendant put gas in it and my mother drove it home. It sounded awful. The guy got fired and my grandfather had to put in a new pump.
