Gotcha. I think the S63's are worth having because even if they have the same problems the N63 has, its 150 more horsepower, so the juice is worth the squeeze. I am pretty sure I have bad valve seals in my cylinder head as my N63 eats a quart every 1,000. I just keep adding and dont sweat it. Eventually the cats will go bad and I will need to go to a catless downpipe, change to custom tuning or off the shelf that turns off the catalyst monitor. I almost wish this was a pushrod motor, then the seals could be done very easily with the cylinder heads on. You could do that with these motors, but the vanos, the cams, and the timing chains would all have to come off (I assume) to do the seals with the heads on, and that is not a small job
