Diesel Engines: Clobber the Slobber

Dear Half-Mast,

Lately, we’ve noticed oil leaking from the air box drain on our truck’s Detroit Diesel engine. Any ideas on how to stop it?
Dear Sergeant,

The 8V9TA Detroit Diesel engine used in some tactical vehicles is a two-stroke engine. A natural output of that type of engine is slobber, which is partially burned fuel and condensation that drains out of the hoses connected to the air box. This usually happens during long periods of low idling.

The best way to prevent this is to run the engine hard, under load, until it reaches normal operating temperatures. That’ll help clobber your slobber problems.
