Hey -
Although I'm sure you're aware that hydraulic lifters can take up to a half
hour of normal running to pump up, you don't want the things rattling around
like that indefinitely- there's a potential for damage to lifters, pushrods,
rockers and valve stems.
I would start by adjusting 'em in a half turn at a time, checking
compression after each adjustment. Max turn-in is 2 full turns - of course -
but if you start to lose compression, back off to the previous half-turn
mark. My feeling (and experience) is that if the valves can close all the
way every time at all speeds and the valve train is quiet the engine will
run well and no damage will be done. We have also experienced the
no-compression-with-proper-adjustment phenomenon, occasionally, only (so
far) with waterboxers and the above procedure has been our remedy.

Subject: 6 mils of lash...
All,
OK, I did it... Finally. Last night (I did my heads a couple of weeks
ago) I adjusted my valves to 6 mils of lash. My poor wasserboxxer sounds
like a coffee can, full of ball-bearings, rolling down a hill. There was
one adjuster turned all the way in! I wish I saw that when I put the rocker
assembly back on. My idle is a little screwy now. It is up at about 1600
RPM. I am going to adjust the valves today (now that my lifters are "all
pumped up"!)when I get home. Will my idle be OK after that, (I hope)? It
was fine before I did the adjustment last night. It doesn't make much sense
to me. Thanks for your reply.
