Cayman
As the Cayman got newer did they get away from the IMS concern? I find info stating IMS repair for up to 2008, but not after. Making me think that they updated the engine and no longer had trouble.

the 987.1 from 06-08, had the M97 , which had an IMS but not too many people have had problems with. Most problems seem to be con rod bearing related and/or oil starvation in track cars. 09 and up, the 987.2, had the 9A1, which is a completely redesigned motor, which doesn't have an IMS. This is a more bulletproof motor than the M97, but seems to have problems of its own, like cylinder (or bore) scoring. The experts advise staying below 3-4 K rpm until the motor has warmed up.
