Wondering If the Cayman have the same IMS problems as the Boxter.
 

Hey guys. Does the 2006 cayman have the same IMS problems as the Boxster's .Or did they resolve the problem by then ?

Thanks.

2005 - 2008 failures are very rare in the Cayman or Boxster. Porsche revised the design of the bearing to be stronger but did so in a way where the bearing can not be serviced without taking apart the engine. Not an issue if you don't plan on driving the car a lot or keeping for a really long time. The bearing will probably outlast the engine if both are properly maintained and driven.

For 96-99 Boxsters, the IMS is not that big a deal since the it has two rows instead of the problematic single row. The dual row should however be replaced when the clutch is replaced to play it safe.
For Boxsters from 2000 (mostly) thru 2004 the bearing can also be replaced easily. So the issue is largely overblown now that there has been a way of addressing it for many years.
Your more likely concern engine wise are all the other ways an m97 engine an fail in a Cayman or Boxster just like the very similar m96 engine found in the first gen water-cooled Boxster and Carreras.

IMS on a 06 Cayman is not as much of a worry as with the prior Boxster. Cylinder scoring on the other hand is a real issue with the Gen 1 Caymans. If you have any plans to track the Gen 1 Cayman I would educate myself fully these cars have many weak spots and require $$$ to address.

Cayman isn't special.. Cylinder scoring and failed rod bolts account for most M97.21 failures here. Don't worry about the IMS, at all.
