So I have a 2000 coming my way, and I am pretty sure the valves need to be adjusted, just guessing.

I think the shims are $10 each, but I won't swear to that. 16 shims is $160, ouch.

If it happens that one or more of the shims being pulled out are happily the correct size for a different valve, can I reuse them or will that wipe the lobe?
