In looking at the drawing in the above post, You can see the o-rings.
I got this pic from Alldata.
I could not locate the part number or the torque spec of the Start bolt head.
The Ru. EPC does not >to my surfing experience> break down this area.

Does anybody on this form have the DVD for the W210? Is the part broken down on the DVD?
Is it on the factory EPC

Bill
