Detroit Diesel offers a kit that routes the air box drains through check valves into the crankcase. The kit only works on upright engines so I had to roll my own as others with GM busses have done. My installation is documented in the files section of the Yahoo group 'GMbusnuts'.RegardsJerry 4107 1120
Dallas, I can remember (we might be getting off topic here) years ago I was called to Anderson Memorial Hospital in Anderson, SC to solve a problem with 3-750 KW generator sets, 5 automatic transfer switches and a paralleling system which wouldn't transfer back to the utility....bumpless. That means that when the power returned the Emergency power system (3 generators in parallel) wouldn't parallel with the Utility...remain connected and then the generators would drop off line.It took me, another Tech and a whole trailer load of inductive load banks 3 days to find that a twisted pair of 16 guage wires had been installed in a conduit with generator sensing leads...and it should have been isolated off by itself.During that 3 days I was on the telephone with the best Engineers the factory had...and their best Field Techs and everyone but Jesus!These Factory Geniuses are paid for what they're supposed to know. Is that the old Peter Principle?NCbob

It would be very difficult for a factory guy to diagnose something like that. What would make it even worse would be that if the system had worked for some period of time and then started messing up.
