The hex size is 7mm or 8mm, I cannot remember exactly. If memory serves right, it is 8mm. By all means check the water pump, but this is separate from the distributor rotor. Replacing the timing chain is not a trivial task. The upper and lower timing chain covers have to be removed and the lower cover is especially difficult due to the high tightening torque used to attach the vibration damper hub to the crankshaft (320 ft/lbs). A new timing chain is relatively cheap but, as with all parts on the E32s, cheap parts are ALWAYS offset by the amount of work and degree of difficulty required to replace the parts.

: I don't have an answer for you, Isiah, but I was told that if you are going into that area, you might as well check your water pump. And if you're going to check your water pump, you might as well replace your timing belt, or chain (approx. $20.00 for such an important part, would ya believe?). Just a thought.

: : What size Hex wrench is needed to change the distributor rotor on a 90 735il? My 1/8 was too small and the next size I had was too big. At least I now know why my car ran rough. There was all kinds of crud on my contacts for the distributor cap and rotor. I can't wait to get the new one one. Thanks in Advance.
