Appears nothin' Harold. You've PROVED you have more power. You used someone
elses experiment and got the same results. That's CONFIRMATION of
consistant improvement in RESULTS. That's why Bentley has contacted Bob for
info.

My question for Bob is, are all the problems associated with pressure only,
or are some of these lifters failing to seal and collapsing. Is it an air
bleed issue or is it an oil seal/valve issue or both.

I have direct knowledge of 20 or so Wasserboxers. In every single case of a
tapping motor I have seen, a factory filter resolved the issue unless the
problem was tar in the crankcase and the  lifters were obviously clogged. I
cured that one with a German crankcase cleaning treatment and the prob went
away in a 'coupla hundred miles and several years now with better lube
maintenance and no further probs.

That's not a very big set, but big enough to make me think a bad batch of
lifters have come through a number of times. I have always used factory
setting and have yet to have a comeback for noisy lifters, unless, indeed,
they had a quickie oil change and a $1.63 by the gross perty colored
filter. Factory filter=immediate results.

If they put Bob's revision to procedure in the Bentley, he will certainly
earn the title Neandereer. That's how you can tell. They're the one's that
write the book.
