Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

There don't seem to be enough of the Series II cars (either 987 or 997) running around yet with miles to say if the reliability has been increased or not....

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

2009 and up eliminated the IMS so that problem cannot occur. I am hoping and keeping my fingers crossed that these motors pass the long term test in the real world. Only time will tell though.
An 08 has an M96 series engine, which have the much maligned IMS. A 2010 car is a Series II car (09.5-up), which has an A96 motor, with no IMS, and direct fuel injection. There don't seem to be enough of the Series II cars (either 987 or 997) running around yet with miles to say if the reliability has been increased or not....
Its going to be very interesting in a few years time when the new engines have some miles on them.
The way I understand it (somebody correct me if I'm wrong), the whole reason for the IMS being there in the first place is to lower the timing chains speed down (as the camshafts run at half crankshaft speed, ie at 6,000 rpm crank speed, the cams are turning at 3,000 rpm). Without the geared reduction in the newer engines, the timing chains now run at engine speed, the camshaft speed reduction being at the camshaft sprocket.
I wonder how the timing chains and (especially) the tensioner guides are going to put up with this?
Lets hope Porsche have done their homework - I would hate to see in a few years time a whole new industry devoted to having to replace worn timing chains & guides as a matter of course aka the older IMS bearings......
One of the subject matter experts said on the Pelican Parts forum that the 9A1 "does not have an intermediate shaft, but appears to have some new problems associated with the timing chains. Only time will tell if it is as bad as the IMS."

had dealer run vin#. report said engine=987320, and trans=g8721.
i assumed the engine was a 987, so where does the a96 motor fit into the picture? i am a parts guy, just not auto parts so i do understand replacement numbers and number changes that manufacturers throw at us.
thanks, dan
kept reading, my bad
