I don't think so, it's a much shorter chain, so slack/backlash is less of an
issue. Average American V8 has a chain the same size and no tensioners at
all. The tensioner for an Austin Healey and many other British engines is
almost identical to the R16, but it ratchets and locks as the slack occurs.
Nice design. I was going to order one for the stroker to see if it would
work.

I've been meaning to ask this question before, when the subject of shimming
chain tensioners has come up. Is there the same benefit of doing this on the
R16 timing chain tensioner?
