2K? Good grief. Have you had more than one estimate? Is the noise constant
or does it change with the engine hot?
I haven't worked on a BMW V-8, but on my old Rover it is possible to
identify which tappet is noisy with a stethoscope. But with those you
replace them all anyway - if one is noisy the others will follow.
