I am posting this question here and also in a couple of other forums. I am in the process of replacing the head gasket on a M113.980 and I need to know what size the socket is for the CAM sprocket (E18 or E20) and I also need to know what size for the oil filter to the front cover bolt the one inside the oil filter housing is it a 40mm or what?

Thanks for your quick reply

 

I know I am replying to my own thread but I want to make sure if anyone else needed this information it is available.

The Oil filter housing is a 46mm and the cam sprocket is an E18.

Also it is cheaper to replace the head bolts then to have your mechanic measure the 10 of them unless they have a go no go fixture like the one I built for this task.
