Maybe he should've tightened the valve cover down a bit more...:doh:...

Man, that was quite the video. I'm assuming the guy that could afford to pour that much money into an engine can also afford to lose it.

That thing at the end sounded a whole lot like a run away Jimmy-----a sound I have first person knowledge of :wah:
Ben----is that engine prone to run away?
There was also a few puffs of white smoke in the runup that would have concerned me :help:
I think any engine that has a source of incoming oxygen and some kind of fuel (even antifreeze) can trigger a runaway...With the modifications those engines endure I would say, yes to the possibility...And I agree on the white smoke - I would have shut down that second...:boom:...BenQuote:

The "E" stop was to my left and slightly behind me---by the time I realized what was happening and got hold of the "E" stop it was all over :yuck:
We ended up rebuilding the engine down in that hole. I would have dropped a crate engine in it but couldn't get one quickly enough.
That is the only engine I ever had run away. I have never heard of a Cat running away----and they do not have "E" stops on them either.
Think of the implications involved with a runaway jet...Note the Brits improvised a few pallets for their test stand, and I suppose if it got loud enough they might have remembered the ear plugs...:omfg:...Ben

Off on another tangent :maybe:
I once did a lot of work in a Firestone Tire plant in Pottstown, PA. The plant had been the home of Jacobs Aircraft Engines.
This was a war time plant. The roof was dead flat with parapet walls so that it would hold rain water---trying to look like a lake from the air ::doh:
In the basement were "test cells". This was a row of about 10' x 10' spaces with about 12" thick concrete walls on two sides. They would put the engines, on test stands, and then run them at full throttle for a minimum amount of time----if they didn't come apart they passed :splat::flower: By the looks of the concrete they had more than a few that failed:run:
That was in the early 70's and there were a few guys still there working for Firestone that had worked for Jacobs.
The only time I've seen an engine blow in person (other than at the race track) was when I first moved to Utah. A lady started her car, when the temperature was zero, then revved it to high RPMs and it noisily failed in a huge puff of smoke.

Only actual catastrophic failure in front of me was a lawnmower.. loud exhaust noise instantly became the quiet “whoosh “ of fan blades.. huge puff of smoke and oil everywhere as I had a front row seat to a broken connecting rod trying to escape from the newly opened block orifice..
Small potatoes in the big picture..
