Anybody even broken the bolt that drains oil from the frame? Rather than tightening it until it felt tight, I decided to follow the manual's 23 NM with my torque wrench. At 20 NM, the head of the bolt almost sheared off. Luckily, I was able to back the bolt out and get a new one for $1.07 from a local dealer. Maybe I need a new torque wrench, but it didn't seem like I was putting a lot of uumph on it when the bolt head broke.
