We called this "flinting" an engine when we did it to 6v53detroits. They would idle so long they would gum up and when you stepped on it there was a cloud you could see for a mile plus it had no power for a while. Once it got real bad we'd pull the air filter and at a fast idle throw a handful of scouring powder in. Couple rev's and see how much it smoked, maybe do it again.

Worse case scenario, we sent the engine to second line for rebuild.
