I love my Z4M to death, but nearly every time I drive it I still have that thought in the back of my head "Was that a knock?". Mine has 75k miles on it now, and I'm rolling the dice. There are tons of examples of S54s with well over 120k miles on the stock bearings. I also don't pound the crap out of my car, don't track it, and always allow the oil to heat up before I go over 3k RPMs. A nice Z4M owner here on the forums last year changed his bearings out of preventative maintenance, the shop screwed it up, and his motor blew. It's been a nightmare for him ever since, and has reinforced the idea to me that if ain't broke, don't fix it. |
This is my train of thought also.
