OK guys... here's a twist. I have a 2005 997S and Porsche just replaced the engine due to a cracked clyinder liner. The NEW engine number is: M97/01AT68666694. Any idea what the "AT" signifies?

ouch - sorry to here about your engine. If I might ask, how many miles were on it when you had the failure?
Did they give you a reason why they believe it happened?

No reason given by Porsche, but forum research indicates lack of coolant to the right rear bank.

"The information on the IMS/engine number were extracted from the 2005/06 workshop manual. The info is on page 426. I believe you can still get a copy @ 997 6speedonline. As for manufacture date, there is no way to tell, same as for a VIN."
"To determine if your M97 engine has the improved IMS, you will need to check your engine number.
if the engine number is 68509790 and below, unfortunately it still has the smaller removable IMS bearing.
if the engine number is 68509791 and above, it will have the new large single row IMS. The IMS cover also has the 22mm nut.";

I would assume that as part of the IMS Lawsuit Settlement that Porsche had to disclose which vehicles were built with the smaller, replaceable IMS bearing. This VIN # checker will tell you if your car is part of the IMS Settlement and therefore, whether it has a version of the smaller bearing or the larger, non-serviceable bearing.

If you have an '05 or '06 vehicle and entering the VIN # in the box reveals you don't have a class vehicle and if you combine this VIN search with the engine # search from this thread and both say you're OK, then really, you're probably OK. Although neither test by itself is may be 100% accurate, combining the 2 should give you that much more peace of mind. If you ever replace the clutch, where you have to pull the transmisison, that would be the time to check for sure and have 100% validation that you're OK.
