Never mind the broken exhaust hub...the bearings look good...for an S54.

Not sure if you can tell but there is no copper showing. The journals looked good and all measured to .002 with plastigage. I think it supports my theory that doing the rod bearings between 80k-100k is about right.

Yeah I was going to say, top row doesn't show any copper. Impressive.

I think most folks use blackstone analysis as a guide as to when to do it?

Might not help if you buy the car used but oil sampling every couple of oil changes to establish a history is a good approach.

Iíve gotten out of the habit of using oil analysis with my E90 M3. My e46 is a track car so I can yank the motor in 2-3 hours. Not much of a hassle to do rod bearings whenever.

2-3 hours...:jawdrop: How many do you go through a year?

I donít have AC, heater core, emissions equipment and a bunch of other stuff. Makes it way easier!

Disconnect the driveshaft, drain the oil and coolant, pull off the front end, drop the front subframe, remove the intake manifold and it pretty much just comes out.

I just changed mine last week with 135k miles on them. I reckon they could have lasted at least another 10k miles.
