My 06 is sitting at 19,999. I thought I was going to hit 20k the last time I went out, but hit the garage before 20 came up. Now I will will be waiting a while to drive her again... I have had mine for 8yrs.

Mine just hit 77k and it feels stronger than ever! Same bearings, VANOS, etc. Only parts I've replaced in the past three years of ownership were the alternator and starter recently. |

25K miles on my car in the last two years alone (78K total) - it has been a DD minus a few months where I had an extra car. For what it's worth the car seems to be happier being driven regularly than sitting for 6-10 days at a time, minus the exterior wear n tear

Original motor. Rebuilt Vanos, new timing chain guide, and rod bearings at around 125k miles. Also rebuilt alternator a while back when the voltage regulator went poof. Car looks like hell but runs great. Leaks a bit of oil from somewhere (or everywhere) on the front of the block.

This is all great news, I plan on having this car a long, long time. The only option I had for replacement was an Alfa Romeo 4C Spider, but even getting past the fact it isn't offered in a manual, I can't FIT in the car. Nothing looks better than our cars anyway, when I parked it next to the 4C I actually liked the look of my car better! |

I'd had two Indie shops now tell me to leave the bearings alone, but upgrade/refresh the VANOS when possible if the engine is over 70k miles or so. Both said it's not a requirement, but good for peace of mind. Neither place reported to me they've ever seen spun bearings on an S54, and they have cars come in all the time with over 100k on the motor now. I was leaning hard towards having them replaced, but a horror story from another forum member here after what happened to his motor from what was supposed to be preventative maintenance on the bearings swung me to the "if it ain't broke" camp. I'll probably have the VANOS done within the next six months or so, then just enjoy the car for a long time hopefully.

Lead in my oil went way up, so I decided to play it safe.
I knew the timing chain guide was a wear item, and given the miles on the Vanos, since I was taking it off anyway, might as well put on a rebuilt. And, or course, there's the friggin' Vanos exhaust hub.

Just picked up my 06 Z4MR.. currently sitting at 27K miles.
Black sapphire / imola Weekend warrior, garage queen. I also talked to a couple of Indies and was also told not to worry about the road herring issue. One of them recommended liquid Molly MoS2. Did a quick search and found a few good worthy threads from other S54 owners. |

As for rod bearings, it's not a myth at all. At the very minimum, I'd do Blackstone oil analysis. My numbers look horrible, so I'm doing a short interval. If it stays bad, it's time to tackle the rod bearings |

Really not sure about some of these preventative steps being cited here. There's so much conflicting advice/info out there related to this engine. |

Many including myself are adding Liqui Moly MOS2 to the oil. Not sure of any data to support it; however, I've read and talked to folks that have seen it dramatically reduce the wear on our bearings. 11 years, 1 month and 34,000 Miles here.

As far as I'm concerned, rod bearings in a very high revving car like the S54, S65 and S85 should be a wear and tear item. My 2 cents. P.S. Keep in mind I'm all the way at 90k, so this might not apply to garage queens
