I think he is getting VAC bearings yes. I went BE, but others have used VAC without problem. Up to you I guess. He can install either, but you might have to get BE yourself...

I would just go with what he already has it'l be simpler but damn, 3200$ is still a lot. I'll have to save some money aside before getting the car. |

It's a rabbit hole. Do enough research on this form and you'll find users slamming VAC bearings for poor business practices, others praising them showing absolutely no wear after 50k and others dictating it's the rod bolts and not the bearings at all.

I was initially looking at BE as well but went with VAC as it was easier (BE was back ordered at the time) . Neither of them are really a proven fix, but offer solutions that are better than stock ones and little peace of mind (which is why i did it). Just an FYI when Rocco showed me my old bearings they were in good shape (80k 2012) , he told me I really didn't need to change them at the time but it was always on the back of my mind so i did it anyways. yeah its expensive but still not as much as what i spent on my old N54 (6 Injectors, Valve cover, etcc )

Yeah, I mean I'm ready to take the hit if I know these new bearings can at least outlast the KM that's on the car right now, 90 000km, and not worry about it anymore. I asked BE bearing if same grade oil stays with theirs and I suppose with the VAC 10w-60 is still to be used? |

http://www.m3post.com/forums/showthr...1253084&page=5 See post #96. Those are VAC bearings removed after 1500 miles. Perhaps poor installation? Who knows. |

It's LiquiMoly's MoS2. They're the same thing, both are MoS2 blends. Molyslip or LiquiMoly MoS2 are analogous. But I suppose technically it's not "Molyslip" indeed.

I did the calculations and I save a good amount if I get the BE bolts and bearings instead. He quotes me 1600$ labor and the BE bearings and bolts come up to around 1200$ CAD total 2800$ instead of 3600$ with the VACs. |

Originally I had my mind set on ordering BEbearings but I spoke to several people that do engine tuning and building and VAC seems to be the more sought after choice. I trust VAC since these guys take apart these engines on a regular basis, and I know several M3 owners using VAC bearings without an issue.
That being said both brands are great replacements since they do offer a "clearance" fix. So regardless of whichever one you go with its still better than OEM. However I do feel its a band-aid to the bigger issue with the S65, you change your rod bearings and you still have a chance that the main bearings will go also. Best to run these engines from new with MOS2/Ceratec/Molyslip, but for those who haven't its a good idea to start! = |

But main bearings failures are pretty rare right. I just hope that, if I change to BE bearings and let's say the main bearings goes, and I call BMW NA and they agree to help but realize the rod bearings were change to something else they might be sorry not OEM. So molyslip oil is the one to get now? Where was this discussed? I was planning to keep on usin' 10w60 from the dealer. All the post I read of oil most people say that. |

So stick with OEM oil but add molyslip? It's just an oil additive? Is this the one? |

Stick to 10w60 and Molyslip and you'll have greatly reduced wear. Also, in the event your bearings do go, Molyslip may save your crank and prevent the bearing from spinning, giving you enough warning to actually fix the issue before the motor grenades. I vouch for VAC with ARP bolts so far. I installed mine almost 40,000 KM ago.

These motors still have a main bearing wear issue so you may as well protect yourself against that.
