<br>
Indeed. I have a feeler gauge set that is round wires rather than flat <br>
blades, and it makes this measurement a lot easier. But if your rocker <br>
arm tips are wearing unevenly, you've probably gone through the hardened <br=
>
surface (and might also be getting wear on the bushing that you can't <br>
see) ... so it might be time for a rebuild. More about that in a second ...<=
br>
<br>
I use a tool called Gunson Clik-Adjust to set valve clearances, because <br>=
it takes the entire wear of the system into account. Rather than <br>
measuring only the clearance at the tip, it works from the point where <br>
the entire rocker arm system is tight against the valve stem and then <br>
backs out in a controlled fashion. It seemed hokey, but it works quite well.=
<br>
<br>
When I first got my TR4A, it had really low oil pressure. I did a bunch <br>=
of work on the bottom end, to little effect. Someone suggested the <br>
rockers - the shaft and bushings were *very* worn to the point that much <br=
>
of my oil pressure was disappearing there. I sent the assembly off to <br>
Rocker Arm Specialists in Northern California; they transformed my worn <br>=
out rocker train into a thing of beauty. I sent them a lot of work over <br>=
the years (and sent a lot of others their way). Sadly, the proprietor <br>
sold the business in order to retire, and the new owners didn't make a <br>
go of it ... but it appears that they're back!<br>
