I would love to do this. Price for each unit is 540.00 in today's age.

If you can live with the tapping/knocking I would think everything will be ok. It will be just..........well..................noisy!

I couldn't stand it any longer and had to fix it. And like I said, I'm glad there wasn't anything more sinister going on which would involve going deeper into the engine.

There is another option that worked for someone but not for me:

Change the oil to 10w-60. It's a thick oil (goes in the M5 I think) that might mask the noise. And that's all it will do...........mask! Probably won't be any good for the mpg either.

Anyone doing this job will also need a torque wrench for left & right hand threads with a minimum of 125Nm. A multimeter (preferrably with sound), a 27mm open end spanner and a T55 torx bit. And of course the special tools. This is the kit I got:

BMW M60 M62 Master Camshaft / VANOS Timing Tool Kit : eBay Motors (item 270570593582 end time May-27-10 12:27:48 PDT)

It will come in handy for if/when the chain guide rails give up. Or you could hire the kit out to others with the same problem maybe.

Yes, it's an expensive fix :shakehead: but.......................how much do you love your car? :smokin:
