On the other forums, it's becoming a fairly common occurrence (especially considering the low volume production of E86///Ms) that the passenger-side motor mount bracket fails. Specifically, it appears the factory 8.8-rated M8x35 bolts that attach the engine mount bracket to the frame back themselves out over time so that eventually the remaining bolt(s) shear off and leave the engine listing to the passenger side. The speculation is that the bolts are improperly torqued from the factory (an idea ironically underscored by the fact that Discovery Channel's "Ultimate Factories" episode about the Z4 factory shows a supervisor finding a problem on-camera with the very bolts in question). I've been aware of the issue, and even had my dealership check the bolts 4 months ago, but just this weekend, my motor mount bracket failed. So I'm thinking that the dealership only checked the visible bolts they could easily get to with the hood open...i.e the engine mount bolts to the engine, and not the engine mount bracket bolts to the frame (they would have had to pull the wheels to get to the "right" bolts). The only reason I bring any of this up, is I haven't seen it mentioned in this forum... So here it is! Anyone experience the same issue?
