hi,
Does any one know the code number of the bolts / nuts of the valve cover and to torque values.
David
The 12 acorn style nuts around the outer perimeter of the valve cover are part number 000917-008007. 12 are required. There are no washers shown/required for these nuts.
The three bolts that are in the middle of the valve cover are part number 304017-008043. 3 are required. The associated copper sealing washers for these three bolts is part number 915035-000003.
The torque specifications for both the nuts and the three bolts is 5 Newton meters, or 44 inch pounds.
These don't appear to be available online in Europe, but they do have stainless ones.
Might look a bit silly on an old cover.
