So no failure of the IMS yet but I am worried. I am looking at breaking down the engine before it fails and costs triple to fix. On the 2006 "M97" engine apparently you must break the engine down to replace the bearing because the bearing is larger than the hole for the IMS cap.
Yes. The engine cases must be split. Probably best not to wait. Post how you make out.

'05 C2 with no IMS problem so far at 71K. Daily driver. RMS replaced (at Porsche's expense) at 45K. No other engine issues.

Thanks, at least that gives a date as one data point. Your build date seems to lay some support to LN Engineering's statement that later MY05 cars may have the newer beefed up bearing of the MY06-MY08 997.1s. I believe the Porsche factory started building MY06 997s as early as July '05. (I know someone who has an MY06 with a 7/05 build date.) So April 05 would seem to be a later run MY05.

Did you analyse the oil / oil filter looking for metal fragments? Anything there?

How do I change my vote from no problems to engine just grenaded at 75K miles? Less than one month after CPO expiry, no leaks of any kind till the big one! However, Porsche NA comes through and agrees to cover a new engine and labour for the engine swap.

Wow. After 75k miles they're swapping in a new engine. I'd say that's a decent attitude. Nice to know.

It's great to hear that Porsche covered you.

Sorry for not keeping up but is this the first 2006 with IMS failure recorded on this thread? I thought that I was safe buying a 2006 997.

There are others. It's definitely more rare than pre-2006, but still happens.

Baz and Jake have both suggested that many times (maybe even most of the time) the failure is actually something else that goes first, and the engine grenades, and because of the grenading the IMS also breaks and people incorrectly blame the IMS for the failure.

eg. on post-2005 models in particular other root failure modes may be more common.
