I was taking the head off my '88 300E today. Everything was going pretty well until I tried to remove the three bolts holding the camshaft sprocket to the camshaft. A 4 MM Allen socket is too small and a 5MM is too big. I found a 4.5 MM L shaped Allen wrench, and found it to be slightly too large. To aggravate the situation, these bolts seem to be VERY tight. Is this an odd size? Any suggestions.

I have only found them to be torqx head bolts. I think all of them are supposed to be the t35 or t40.

Benzmac,

Thanks, I will look a little closer.

Take care,
Larry

Larry, when you get the correct torx socket, put it into the end of each bolt and give each one a brisk tap with a hammer. Had the same problem with mine. Heat and time are the culprits.
