I went with OEM. Surprised the WPC coating wore off in only 15K miles. I'll post pics of my other bearings once I'm completed. Having a rough time angle torqueing (105 degrees) cylinder 3 for whatever reason. It keeps stripping. Cylinder 1 and 6 done, 4 more to go. 8 rod bolts remaining Taking a break so I can reenergize.

The rod bolt head. If its not on tight, it will deform the bolt and practically make it useless. Oily environment with bad angles attribute to this.

Sounds like cheap or ill fitting tools to me. Are you using the correct E-Torx? Just because it fits on there, doesn't mean it is right. A proper sized E-Torx socket should fit TIGHT, not easily go on the head. You're probably one size too big.

It's the correct socket, e12, I got cylinders 1 and 6 on without any hitch. 105 degree angle with a 3/8" torque wrench is pretty tough. I just need to find the right position to lay so I can get good leverage without running out of room.

You know what's not hard... a 24 inch breaker bar, 3/8 adapter and an angle torque guage . I'm a manlet if I can do it anyone can.

EDIT: Since most breaker bars swivel down it really helps clearing everyhing while keeping constant motion. I've done it this way on my S54, S62 and S85 something to consider. Also don't set the angle with a torque wrench unless it's a combo deal.

Yes and while you want to be as close to spec as possible. Exactly 105 isn't necessary. I believe it was Forbes who tested the bolt stretch, elasticity, procedure, shear etc...use a breaker bar / angle gauge and get close enough.

I'm using a 3/8" Snap-on TechAngle so it makes life a little bit easier, but the length is only ~17 inches so its a bit tough. But, I was finally successful tightning cylinder #3. I was just laying at a wrong angle and a bit strained. 3 more to go..
