Some people found shavings and broken plastic pieces,replaced just guides and chains,and had no further problems.
My guess is that engine's components are fed with oil passing the filter before,otherwise it makes no sense to me.
I am at the same situation right now...when I bought my X5 it had the same problem,but instead of just changing broken parts I was told to swap an engine...and here I am again after 60,000 kms and 4 years.
So,read more stories..have a look at these two links about VANOS seals for M62 engine.

I've been looking over manuals for the M62, and learned a lot about the Vanos and associated parts. But I haven't been able to find information on the oil path. If the oil is fed from the pump, then through the filter BEFORE the Vanos then I'd actually have some confidence that the rest of the motor has been protected. The only areas that would need flushing would be the timing chain case, and the oil pan. Then it's just a matter of replacing the oil pump, timing chain, guides, and gears. All of which I'm still going to have to farm out to somebody else.
I contacted VAC motorsports today because they rebuild Vanos units. They don't list the M62 as being part of their program, but I figured it wouldn't hurt to speak to them about my situation.
