PA28 Archer: engine write-off at 1200hr

[Mak]

Hi all,

I recently had a nasty surprise when metal was detected in the engine oil of my archer 2. Further inspection showed that the engine was done for. The cause was pointed out to have originated in the crankshaft where some of the cams started to wear. This happened a little over half-life.

I'm curious about your opinions of what may have caused the problem in the first place and whether this is a common occurence.

Thanks.
Mak
