I saw no sludge anywhere, my variocam tensioners were nice and clean (did not stop me from giving them a good cleaning anyway). And I replaced one questionable lifter.

I noticed that, mine all had this yellow almost like yellow passivate finish to everything. there was no suggestion at all of a coolant leak but the only thing I can think of is that an oil additive was added, something like a hydraulic lifter additive. In any case all that yellow came off in the degreaser with no resistance at all
