I have purchased a 2008 Cayman 2.7 with 22K miles at the time of purchase I took out a warranty with warranty wise for peace of mind. After reading about the scoring in the bores I'm glad I did!
Can anybody tell me if the 2.7 is just as prone to this problem as the 3.4? Has anybody had major problems with their generation 1 2.7 Cayman?

Thanks

Thanks for the infomation so far any more info would be good to hear. I'm thinking of using Braunton Engineering who seem to have a good following from Porsche owners perhaps I'll get them to give my car the once over.

My Cayman is not showing any signs of bore scoring at the moment, reading warranty wise info I hope they will cover the problem if it causes a break down, reading their info pack it covers all mechanical problems including if something breaks or stops working earlier then it should. The info i read on the net about them they seem to be one of the best out there, lets hope I never have to use them!!!

So it looks like a warranty is not worth the paper its written on!!!
It will be interesting if anybody knows of this problem on a 2.7 as it does seem to point towards the 3.4S?

Sorry fella but they wont pay out. It wont stop working or break down, just use an increasing amount of oil.

Stop worrying the 2.7 is unlikely to score bores.

The bore diameter is smaller than a 3.2, 3.4, 3.6 or 3.8 and the cylinder casting is different so the amount of coolant surounding the cylinder is greater while the loads on the smaller piston are much less - so overall (as it produces less torque).

It is difficult to know exactly under what conditions a score starts (as it happens in a few seconds) - except that it is a known phenomenon at low revs and high torque.

We get slightly more tiptronics though for repair than manuals - so if more manuals were sold (don't know the figures) that would support this opinion because the tiptronic starts off from standstill in second of 5 gears and the 3.6 and particularly the 3.8 produce massive torque at very low revs (which starting off in second occurs at very low revs compared to someone driving a manual from 1st).

So I think you are safe to ignore any worries and be glad you chose a more reliable version.

Thanks for all the infomation, I am happy with what hartech post as they seem to be the people in the know.
Would still be interesting if someone has had this problem on their 2.7, if no one replies then to me it seems the problem is with the 3.4?
