I have no idea how many were built in '05 and many MY05 cars were also built in '04. I am also not sure if the VIN sequence number is relative to a given market (e.g. US) or is worldwide in sequence. Your sequence number would seem low if it's a WW count, but maybe not so low if it's for a given market.

LN Engineering states that later MY05s may have the upgraded bearing, but nobody knows the exact date the change was made or if it was even consistently installed on every '05 after a given date.

That's why I am curious as to what month your car was built, assuming its oriignal motor came with the upgraded bearing of the MY06+ cars.

You know that your will NEVER have an IMS failure in your 2011 C4S, right?

That is because it doesn't have an Intermediate Shart.

According to the door jamb, my 2006 Carrera S was built in September 2005. No problems as noted in previous post. In fact, the car has been totally trouble free.
Just wanted to post date of manufacture of "2006" model.

My car was built in April '05.

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.
