[TR] Valve Lash Adjustment Method

Terry,
Just went through this on a different vehicle. In my case setting the
valves at the specified 0.006" gap with the other valve for that cylinder
open, left me with NO gap when the piston was at TDC on the compression
stroke, where I should have been setting it. Bearings worn weirdly? Sides
of cam worn weirdly? I'm still pondering but did go back and set them
correctly because you don't want to end up with valves partially open when
they should have a gap, so better to err on the side of looser at the side
of the cam and correct at the bottom.

================
The book I'm using describes adjusting valves when the intake and exhaust
are at the point of balance, at which moment you can set both valve lashes
to .010.
I hadn't noticed that before.  I had always set the valves on the exhaust
when the intake was completely down, and vice versa.

Question:  Does it make any difference?
