I wonder, did he have new rotor housings or used ones? Supposedly you have to use new rotor housings with ceramics because the lack of seal wear means that there effectively is no break-in happening.

Sorry about your friends luck but unfortunately sometimes builders don't know the long term results of the new seals they put in engines that they haven't really tested. It's a crap shoot! I've started 2 threads about "Aftermarket apex seals and your mileage" to help the forum gain some insight on the long term results with hardly anyone posting. Hmm I wonder why? Personally I only put seals in I have experience with. FYI ceramics or not, any one piece seal will most likely have hard hot starting issues when compared to 2piece seals which are self adjusting.

Where's the thread? I have roughly 40k on my current set of Atkins 2mm seals and had 55k+ on another set. The first set died due to dust intrusion - the area where the springs rode was worn so deeply that there was no more spring tension, and the seals were only 1.6mm thick in spots.
