Getting things parallel refers to the sprockets on each of the cam, and the corresponding sprocket on the layshaft. That allows the chains to run straight and true. The access hole at the front of the block allows you to access the layshaft sprocket. You can do this manually, but the custom tool makes it much easier - but I agree, you will use it for just a few minutes.
i have been at this for too long (years not months) and have read your thread. Was looking at your Camshaft Timing Part 1 pix when I posted on this thread. Your photos are great and i obviously need the tool. Noticed you show 4 shims, mine only had 2 when I disassembled oh so long ago. Thanks again for the engine series, i need to get on with this!
You should be fine - but boy I get what you are dealing with if its been years - lots of little details to remember (and then re-remember). I did mine pretty quick so it was as fresh as my old brain could remember it ...
In the vid above when he zeros the vernier off the intermediate shaft (2m mark) sprocket there's a hole that he uses to get all the way back there - is that different from a 964/993? ie is there the same hole on the 964/993?
