Hi Bob.

It is not a case of "my theory". The hydraulic lifters in a '61 Plymouth
Valiant work the same as those in a '95 BMW seven series. Lash allows
engine oil to enter the lifter. When the lash is eliminiated, oil cannot
enter the lifter. For a lifter to overfill the "door" would need to be
open with no lash and I don't think that can ever happen to more than
one lifter at a time.

Adjusting a 2.1L lifter is like trying to position a moving target. I
believe the only way the .006" clearance would work is if you allowed
the lifter to fill to it's maximum travel. However then you would have
converted the hyd lifter into a solid lifter which would re-invent the
cam follower that we got rid of in the '70s.

I'm also interested in the experience of other list members (excluding
any '61 Valiant stories).
