Don't mean to derail the thread....But a shop's image is only as good as the representative representing it. Evolve enjoys a fantastic reputation but like almost every other shop out there, the founder who built that reputation based on knowledge and experience usually isn't the one doing the labor once they're big enough to enjoy such a reputation. The tech on that video is simply incorrect. Unfortunately, the majority of RB's being replaced by well known RB shops, are being replaced by techs who really don't understand what's going on. Furthermore, most of the videos being pushed around are sourced from these types of mechanics. Of course there are some exceptions but the truly knowledgeable sources are usually too busy to make videos.

Example 1: A customer who just had his bearings done by a much larger, more well known, highly reputable shop brought me his M3 because within 200 miles the rod was knocking. Upon disassembly I found the #1 bearing shells were installed backwards (locating tang installed opposite of notch). The tech clearly made a noob mistake and it cost our customer his engine.

Example 2: A highly reputed competing shop in my area purchased BE bearings from us since we're one of BE's vendors. Their tech arrived to pick up the parts while we had two RB services in process, and was amazed that we actually remove the subframes for the service. We were shocked. There's no way to have the same level of accuracy, attention to detail, and cleanliness without removing the subframe. If you disagree, we have photos from the shop from Example 1 mid-service with the subframe dangling, while the tech was busy mis-installing a bearing shell and ruining the engine.

In the case of the OP, I would bet that this is a main bearing failure.
