I had actually planned to take the car in to have an oil pan gasket done.

to your point, I kept wondering myself about how if I just shorten the change interval, obviously things are going to improve (you would think).
I love these cars but this is a real kick in the pants to be honest (after the recent head gasket change on my other Xer). This car was supposed to be my dependable one but it really does appear that I have a fairly serious problem with it after reading up on this topic.
It's just crazy that of all the issues with the M54 and the hundreds of hours of reading for the past 10+ years I don't think I have EVER seen anyone mention rod bearing problems. Not that they don't exist, but that's not typically something i'd have ever bothered to check even if there was a way to do it.

Wasn't sure if your question was for me...if so, there was no knocking of any sort. Caught it in time, there were no crank damage. The 3 oil analysis (attached) following the bearing change validated it.
If you're planning on doing your oil pan gasket, then you're already 80% there. It's a no brainer to do the rod bearings at that point!
I haven't seen rod bearings being an issue on the M54 engines either, but there's an exception to everything. All the rod bearings issues that I've seen/read are on the S54, S65, and S85 motors.
