I finally got a cable that works and ran some tests using INPA and it definitely looks sick... Each cam fails on something:

Inlet #1
  • Doesn't reach required max angle (137.9deg, min is 140deg)
  • Adjustment time for opening seems to fail altogether?
  • Ventilguete (valve?) seems to be maxed out

Exhaust #1
  • Doesn't reach required max angle (122.6deg, min is 123deg)
  • Minimum angle seems to fail altogether - doesn't register a value (did the test twice)
  • Again, Ventilguete (valve?) seems to be maxed out

Inlet 2
  • Doesn't reach required max angle (131.1deg, min is 140deg)
  • Doesn't reach required min angle (73.2deg, min is 74deg)
  • Again, Ventilguete (valve?) seems to be maxed out

Exhaust 2
  • Finally, one that gets in to the green on max angle!
  • Doesn't reach required min angle (80.7deg, min is 86deg)
  • Again, Ventilguete (valve?) seems to be maxed out

The raw results are posted below... As soon as I get ahold of some replacement cam central bolts I will pull the top off and recheck the timing.

Thanks!
