Went for a 45 min spirited drive + some errands that required stop/start city driving. Not a hint of smoke. Despite that, the VCG and VANOS seals are now on the "near future" maintenance list
Yeah, appreciate it. I went out and revved it slowly from idle up to 3500 RPM while parked. No rattle I could hear beyond the usual valve chatter. I'll probably just go with the seals only, but I would kick myself if it began to rattle a little while after I did the VANOS seals.
