2.9 Cayman issues

[M1chaelw]

Don't worry no engines gone pop here

I'm just wanting someone in the know to confirm what I've read on PH and other websites is correct . I'm just about to pull the trigger on a 2010 Cayman 2.9 and want to know I'm not buying in to a lemon . As most of you can already guess I've ready through page upon page of scored bores and IMS failure resulting in 12k bills ect .....

Am I right in thinking:

2.9 engine has no IMS to go wrong

2.9 is closed deck and has the A91 dfi block with improved cooling paths

2.9 had some scoring issues cause by piston rings ? Not the usual gen 1 "s" problems . This was then rectified " I recall 3 different part numbers " the final one being problem sorted.

If the last point is correct , what year was this problem sorted and is there any way to tell if the potential 2010 car I'm wanting will have the duff piston ?

Any info much appreciated

All sounds about right but for the last point was start-up smoking issues rather than scoring; rectified by piston redesign and or DME map changes to reduce propensity for oil to collect in the intake.

Thanks for the reply , any idea when the piston redesign and or DME map came in to production? / any way to check
