What issue are you having/worried about... the actual cam phasers themselves, the timing chains, or the cam timing solenoids?
From what I've seen/read, all are about equally problematic.
I just dealt with one, replacing the solenoids fixed it.
Upon close examination, one of the fine screens in the grooves of the valves was torn and the flap was forced inward, jamming the valve.
I wonder if this is a common failure?
The valves and screens were clean and free of debris, gunk, or varnish.
I haven't heard anything about using a different oil, but using good oil and changing it often is important, 'cause if the cam bores in the aluminum heads wear oil that's supposed to be directed the cam phasers leaks out, instead of pressurizing the phasers as requested by the 'puter.
Sounds like the aluminum crankshaft-driven oil pump wears, as well, and low volume/pressure affects the operation of the VVT sytem.
