So I got under the car and verified this is a replacement engine



M96/23AT65466219


M96/23 = what is the 23 ?

6 = 6 Cylinder

5 = Engine Version

4 = what is that

66219 = Engine Serial Number

I don't know how accurate this is, because it specs "VarioCam" on 2003 and up MY, when in reality the earlier motors have it too.

It means it's a 2004 engine.

Thanks TeamOxford,

Does this means that they replaced the original 2004 engine that failed because of the ims bearing
with another 2004 engine with the same ims bearing that could also fail ?

[TeamOxford]

It means that the original 2004 engine was replaced with a 2004 factory replacement engine. It does not mean that the original engine failed because of the IMS bearing.

But since you mentioned that "there was a line there saying :NV Wty Intermediate Shaft", then it may be safe to assume that the IMS bearing was the cause of the failure.

The replacement engine has the same IMS bearing as the original - single row.

Forgive me for digressing for a moment. So, 2000-2002 engines are designated M96.22 and 2003-2004 engines are M96.23. If both versions have single-row IMS bearings, what's the difference?

Number of chains?

Can an M96.23 engine replace an M96.22?

Basically the 03+ is a three chain and 97-02 is a 5 chain. Heads are different but I believe the short block is the same

Thanks. So they're not a direct swap?

The 2003 2004 had variocam plus, a newer version of the variocam in earlier engines. Someone may want to verify that.
