They came out with the Silver 92. The silver paint was to help slow the oil leaks. :-laf
I agree with Gonzo... a real General Motors POS! It lived too far past its 1930s technology.

I know in the mid 80's that they were slipping but I think some of that was a result of sloppy tolerances and poor engineering at the manufacturing level.
The basic premise of a 2 cycle Detroit Diesel is still sound.
They would start and run under the most extreme conditions, look at what was built in this country using that family of engine.
The fuel system was dirt simple and forgiving of contaminates, the Series 60 (1,000,000 strong and still counting) uses the same basic system only with electronic controls to fire it rather than a mechanical governor and fuel rack.
They were cheap to repair and if you know what you were doing when you set them up they would not run away.
We always had a minimum of three people available if starting a new rebuild, one to start it, one with a big jacket to stuff in the air cleaner and one to take the fuel filters off just in case something went wrong. That spring loaded emergency door will not stop them if they take off quickly.
They would take off if an injector stuck open on the pre-spring loaded rack days, after that upgrade it quit happening.
If an injector stuck while driving it you could control it with the transmission and brakes to get it to a safe stalling point.
Run aways are not exclusive to 2 stroke engines either, I have see 3406 Cats run away on two separate occasions over the years and you had better step back because nothing can be done. One of them turned the stacks blue on a Pete tractor and spoiled the Fuller transmission behind it because the input shaft was spinning so fast. I figured that 15" Spicer double disc clutch would come out through the bell housing but it didn't.
