I think you can save yours by changing the lifter(s)

the lifters install from the top side of the head. you should only have to remove parts of the valvetronic and the valvetrain, not the head itself.

Geez man if your going to do this at least pay $80-90 for the Bentley Manual on amazon, btw I looked at that procedure, and saw lots and lots of (BMW Special Tool XXX required) probably because of the complex VANOS.

Here's a link to the BMW shop manual. It's not intuitive but it has the entire procedure to remove/replace the lifters. The BMW shop manual is not descriptive since it takes into account that you are a trained tech, I actually have the cheap haynes (autozone) manual and it's a lot more descriptive and easy to understand.

I haven't replaced my lifters but I need to, so I've done a bit of research. You need to remove the exhaust cam to access the lifters, to do this you need a couple of special tools that keep the number 1 piston in TDC and the crankshaft locked while you are servicing the head. You need another special tool re-install the exhaust camshaft so it's seated correctly on the bearing guides. You can get these tools but all in all they'll cost around $500 in total. BMW changed the head design to provide better oil lubrication in the lifters (I think cars 2010 and up have this new head revision). Buying a used head from an lci is the easiest way to go.
