Some early 2.5s had slipped sleeve problems, but I think those were from 98 to 99. A '97 2.5 should be OK in that regard. But as the OP mentioned, it doesn't have enough miles to feel god about the IMS bearing.

I'd be thinking about getting an upgraded bearing onto it, pronto.
With the IMS problem, I was somewhat under the impression that the early Boxters were less prone to it. My current plan would be to get an oil change as soon as I get it to Texas and have the oil drain plug replaced with one that has a rare earth magnet on it. I spoke with a mechanic at Zims Here in Bedford about the IMS failures and that is what they recommended. Still debating about the Flat 6 Guardian as well, but at that price, I would seriously consider just getting the improved bearing and be done with it. I'm glad that I shouldn't have to worry about D Chunk though!
