2001 E53 3.0i M54, 186k miles

was running with no problems at all other than head gasket letting combustion gases into the coolant

I've owned for 4 years now, PO had extensive maintenance done, mostly at the dealer. Sometimes incomplete records, but there is no indication of any VANOS work.

So I'm about to start re-assembly during my head gasket repair. The double VANOS is already removed, in hand.

With no symptoms, high mileage, and the VANOS already off the engine, should I go ahead and replace the VANOS o-rings (or whatever is in the kit) pre-emptively?

Thanks.
