Wierd application, hypothetical question.

[Pat Ford]

 There are other run away situations, bad pcv valves and excessive blowby spring to mind, or the one that scared me a ingersol rand 750 CFM air compressor powered by a BIG 6cyl. 2 stroke diesel, the supercharger had a bad oil seal only the quick thinking of one of the operator saved the engine. He discharged a fire extinguisher onto the intake!
