Hello gents,


Can someone decipher the following two sentences from the 993 Shop Manual:


993 shop manual:


"4. Bore inner valve guide dia. to a dimension of "g" = 8.00 to 8.015 mm using a broach or precision boring equipment. In an emergency, the valve guides may also be machined with a special reamer."


Please read the two lines carefully. I asked this question on another p-car forum and the guys were totally confused in their reply posts. I do this work for a living for about 45+ years. I need one of these 993 (8mm) guide broach systems now.


I will go into detail of why this broach system is superior for guide bore sizing if I get some reply posts of interest.
