I was not disputing the accuracy of the statement. I was only saying that unfortunately I cannot testify personally to this being a workable shutdown method. If I COULD, then I would not have lost the engine in my daughters car.

If I had a good running diesel, I would NOT rev it up just to try the method.

I still contend that if the air cleaner is not off the engine, having a 17MM open end in your hand is the best way to go.

If I only had it to do over again.

Have a great day,
