Okay! The planets have aligned just briefly enough for me to get the timing cover off, and the chain exposed! It helps the radiator was out being repaired. More on that later in its respective thread.

Above: The marks line up when rotated. (Not photographed.)

Above: Slack.
I've never done timing chain work before! I've worked with air cooled VWs and their timing gears, I've worked on more modern engines with timing belts. They NEVER have slack. This amount of slack seems excessive in comparison.
Questions:
How much will this affect engine performance?
How will it affect engine vacuum?
Can anyone tell me about this timing set? Doesn't seem stock.
Regards,
Mike
