lifters [was: 130hp 4KQ motors?]

[Ken Keith]

Solid lifters are as you describe.  Hydraulic lifters are exactly the 
same, but they are filled with engine oil and expand to fill in the 
space that the shims would if they were solid.  I imagine they have 
little springs in them that keep them extended, and the oil filling 
functions to dampen the compression.

A rocker arm setup is different.  Hydraulic lifters go in the same 
place, in the same manner, as solid lifters.
