Engine mishandling question, 6 cylinder continential

[poonpossum]

I am wondering if anyone has any input on what could happen to an engine if the prop was to redline for near on half an hour. We are talking a six cylinder continental here, close to the end of its life.

The engineers found shards of steel all through it, in the oil filter and everywhere, and I’m pretty sure it would be probably directly related to the fact that it red lined for so long, but am looking for another opinion.

what are the engine maker's specifications?

Continental O-200's are typically run at 2500 rpm continuous because that is an economical fuel burn. BUT look at the Continental engine specs and you find that the O-200 is actually certified for continuous operation at the redline of 2750rpm. that is you could run the engine for all of it's 2000 hours to TBO at redline and still be within maker's specifications ...which is not what most people would believe.

so don't solicit opinions, they may be nonsense, look at the manufacturer's published data for the engine and be guided by what they say.

O-300's have two more of the same cylinders used on O-200's.

Probably another cause, engines need to demonstrate a 150 hour full-power run during certification. Too little information to help.

Shards of metal in filters etc don't sound good, did the engineer specify what kind of metal?
