think im gonna stay outta this one

even so that's not the timing causing the compression loss, it's knackered pistons.

think i know.... but who am i to know???

so ill sit on the bench and let all the 'know it alls's give there bit....

Pinking is pre-ignition which is when the mixture ignites before the compression stroke has been completed, hence why eventually the piston crowns will burn out.
This can be caused by timing being too advanced, fuel which has a low octane rate so cannot resist detonation, hot spots or a burnt out valve.
Anyone want to add to that? 

this is correct
pinkling is not caused by cam timing but ignition timing
