Hi,
I know this has been discussed at length before, but here I go..........
I've just rebuilt a 1989 2.1 liter using the old lifters (150,000kms, 95,000
miles).  Now it seems the lifters do not want to bleed down/adjust properly.
They behave like solid lifters.  The lifters sat on my bench for about a
week, all in an upright position.  I did not disassemble or do anything to
them.  Just put them back in as is.
Engine now has about 300 miles on it.

I tried adjusting with 2 turns of preload like Bentley says.
Then I tried with zero clearance, zero preload.
Then I tried with 6 thou of clearance, cold.
With 6 thou of clearance hot compression increases 10 - 15 psi over zero
clearance - zero preload.

Whats going on here?
Any ideas?
Will more hours on the engine have any affect?

Thanks
Gary
