Greetings Everybody -

I remember in my '71 "Campmobile", valve clearances were adjustable.  My
sense is that in my later 2.1 wasserbies, what with hydraulic lifters,
there's not much that I can adjust.  I am getting a pretty hefty tapping
sound these days, although it does sometimes disappear.

I'll take a few suggestions, if you have any.

Many thanks.

Sam
