I just swapped out my cam & rockers in my 88 260e M103. I bought a used head that was redone to pull the cam and rockers from. Thanks to the info in this forum all went well until I was buttoning it up when I discovered the rotor driver on mine would not fit. I imagine the new cam was the updated cam. The driver was about 2mm too fat and 3 mm too long. I live 75 miles from a dealer and have no other car. I mounted the driver in a drill with an engine stud and spun it while I ran a file over it to cut it down till it fit and extended the same amount out of the cam as the old one. I could not find a 7mm internal hex bolt so I used a hex cap bolt (hard) and ground down a socket to fit in the hole. The cap installed easily and the car fired right up. (nice not to have the tick!)

My question is do you think it is safe to drive to the dealer on monday to get the new driver?

Thanks

Charlie
