[Vwdiesel] Camshafts ---- ( missing key mystery )

[H.Hagar]

I had to look deep in my Teacup for this one.

 The camshaft sprocket slip problem.

Here it is , its coming in clear now .  Mark Shepherd was so paranoid
he took to over-tightening the bolt. Val Christian said he had one slip
that was installed at the factory.  (was some of them a result of turning
engine with socket ?) I said I was flabbergasted having rubbed elbows with 
Germans for many years , let me tell you they pin even radio knobs.
The cams I have here does indeed have a slot for a woodruf key. But
the sprockets have no slot.SO it is important to make sure the sprocket
does not slip.How to tell ? did it slip ? next time. Make a timing mark under
washer . Piece of cake with an electric marker.From now on all mine will be marked.
33 foot pounds according to my Bentley, on bolt.Sounds reasonable to me
looking at taper.

Did I use the bolt for turning engine ?  yes but I could see keycut in shaft
so I figured it was keyed. 
I tried to call VW on my dial phone , but they did not answer.

Hagar.
