    The OM352 is a long stroke motor, so it may not compare favorably to the shorter stroke civvy car engine. In my case described above, I was able to dump the clutch and stall the engine, but that was after a few seconds (it seemed like a minute!) of confusion and assessment of the situation.

    If you want to get your blood pressure up, I bet a runaway engine is a great way to start.

    The fire engine that my brother drives has an air intake valve that will close if the engine runs away.

    I had a Detroit 8V71 that had a spring loaded flap above the blower to block intake air in case of a run-away. It was engaged by a dash mounted emergency push button. I heard that on a worn engine it could run on oil bypassing the rings.

    Considering the threat to life-and-limb of a runaway, you'd think manufacturers would automatically include some kind of feature like these for the problem; neither one seems complicated or even costly.

    But...this isn't anything like a perfect world though, is it!?

    I was given strong instruction when first starting a diesel that had IP or injector work to have the air intake readily accessible and a large rag to block intake should things go south.

    Why? Concerned it will get sucked in? I'm talking Turkish Towel kind of rag in a code red situation.

    Well, don't forget that if the engine is running backwards, exhaust will be coming out of the intake and a guy could get a badly burned hand real quick.. the exhaust pipe will be the intake, so that would be the one to block off.. I saw a red shop rag go thru an engine once.. came out the other end in piles of red threads..
