My 006 distributor has no mark to show where the #1 cylinder fires.
What is the best way to locate this spot and then to mark the distributor?
Also--wht wouldn't the dist be so marked in the first place?
Thanks to all---Jack

I don't think you need a mark Jack. Just pop the cap and turn the motor over by hand until the rotor points at the number 1 spark plug wire in the cap (the one nearest the crank pulley). Then look at your crank pulley. You should be near TDC or BDC.

Jack:
If the engine is assembled with the distributor more-or-less in the correct attitude, then, when looking down on the top of the distributor with the cap removed and with the crankshaft set at Top Dead Center of the firing stroke, the rotor should point more-or-less at 1-2 o'clock around the distributor housing. It should also be pointing right at the plug socket for #1 cylinder.
Somewhere in the vicinity of 1-2 o'clock there should be a small scribe mark on the lip of the distributor housing, right where the cap sits on the case housing. It's only 1/8" long, perpendicular to the housing circumference and often easily missed or overlooked, but it should be there.
THAT is where the rotor should be pointing at TDC of the firing stroke. In fact, there should be a corresponding scribe mark right along the center of the rotor, pointing at the scribe mark in the housing.
Go take a look and see if they are both there......

Gordon,
I think the mark is more like 4 or 5 o'clock. I just double checked in the Bentley manual.
Maybe you are looking from the side of the car instead of from the rear.

The position of the rotor is ""usually"" far different then Bentley's manual describes. The reason is that the cam gear can be installed in any position within a 360 degree circle. The Bentley book describes a totally stock VW factory built engine that hasn't been disassembled.
A lot of engine builders just drop the gear into the case and don't care where it lines up.
Jack. Just remove the distributor cap. Rotate the engine until the rotor lines up with where the #1 plug wire attaches to the distributor cap. Rotate the pulley until it reads TDC then lightly chisel a notch into the top edge of the distributor body.
The old 009 distributors had this mark but the new replica distributors do not. The reason was the old 009 distributors retarded #3 by about 2 or 3 degree's to help keep it cool.
