I changed my clutch last week. I saw some oil at the bottom of the transmission right at the engine and a drop or two on the garage floor.. So I bought a RMS. RMS was fine but the IMS was seeping, maybe 4-5 oz total-- some old and some new oil. It made a mess in the bell housing and the back of the engine. LN engineering literature indicates I may be looking at a failure. It is a 2006 997s with 55000 miles, never abused by me but I am the third owner. The car was in New Mexico when I bought it, the owner said he put 12000 miles on the car. Stottard sold the car to the first owner so it was up north for awhile.
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.

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.

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.

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.
