So i have 50k miles on my 2006 S85 which from what i understand means i have the old style Vanos oil pump gears. Getting ready to do the bearings, vanos line, pump etc...
Should I update the Vanos Oil pump gears in addition to having the pump rebuilt?
Is it just the gear on the pump or both the pump and the one on the crankshaft?
Can the pump drive gear on the crank be removed from the front of the engine where the front main seal sits? (See Picture)

Both crankshaft and pump gears have to be changed out, it would be a good idea to change the chain tensioners to the main oil pump for the updated version also. Guessing you've got the single drain oil sump pan also, maybe check around to see if you could either get the later twin drain sump pan or maybe get a shop to install the second drain plug in your existing sump pan.

Yep, single oil drain pan.
My bigger question is do I need to remove the block bed plate to replace the crank gear?

No need to drop the bed plate:


The garage goes through the list of what to change on the early cars at 1m 45seconds in.
