Timing belt change - marks on flywheel and on vibration damper not aligning

[Huw Powell]

Yes, you are.  Please start again and try to be clear.

- Which timing belt "sprocket"
- The camshaft has a separate key that locates it to its timing belt pulley.
- The vibration damper has a machined keyslot to the crankshaft machined 
key.

Use the flywheel to set the timing and ignore the front crank pulleys.
