i had been running at a deviation of around -6 for a while. it was creeping up and i was getting the hard little brown bits in my oil filter, so all made sense then boom, actuator failure, green bits in sump, big jump in deviation.
coincidence? perhaps. or perhaps having the actuator operating a variocam system with a floppy chain hammering worn variocam pads accelerated it's demise (as the porsche +/-9 limit was established before they knew the tensioners and pads would wear so poorly, forcing them to update the parts).
and is the pad wear due mostly to start up rattle due to insufficient oil pressure on start-up? fixed by changing to the updated oil pump piston? or adding an accusump with pre-oiling?
who knows. like the late great kurt said, "just because your paranoid, doesn't mean they're not out to get you" ... drive your car, keep an eye on it, fix it when you find the right combination of time and money.
