Yeah, sure, it might be that it's an old engine. Chances are that a second-hand SR20 that the poster is talking about might fall within the same timeframe so I guess it's relevant what you are saying Jabba.
Does the lean assist work? Probably not very well, otherwise it wouldn't have come back from a long trip away with 83.3% of the clyinders cracked.
Education is the key, the same with any engine and aircraft, so yes, you are spot on Jabba.
I remember one of the guys from our airport visiting Sunland a few years back and there was a half dozen or more Cirrus's in the yard with their engines out and drums hanging off the front, but that would be more likely due to the blocks cracking due to the faulty alternator mounts.
The block on our SR20 cracked for the second time (replaced once already - first time at 400 hours) with 200 hours to run on TBO and I believe it was at the second alternator mounting bracket, again!
Like I said, deep pockets and you'll be fine.
