Charlie Kohler, in part of his post, said:

"To set the record straight regarding the Continental TSIO 550, if the
engine
was produced prior to 2/17/97, it had a problem in that the oil control
rings
had too much tension and did not allow enough oil to reach the upper
cylinder
for lubrication. "

Then, if I read the rest of his post correctly, proceeded to laud
Continental for their perspicacity in coming up with a "fix".

I'm sorry, but it seems to me that Continental has been at the engine
building game long enough to just not have that kind of engineering problem
in a product - EVER! And now, we're being told that there is a serious
question about the metallurgy with a bunch of crankshafts that actually got
into delivered engines. What in the world do these guys have in place for
Quality Control? The picture that comes to mind is some doofus sitting in an
office with his eye on the schedule instead of his QA procedures.

After 40 years in the aerospace industry, it boggles the mind! And I'm not
just picking on Continental - I had a factory Re-man done on my Lycoming
several years ago and what I got back was just barely good enough to be a
boat anchor.

I can't find it in me to make ANY excuses for such poor quality.
