[TR] TR3A Rocker arm "spacers"

But that doesn't answer the question.  You need to specifically check for
oil flow _through_ the rocker, to see that the bushing inside is being
lubricated.  The passages to the rockers are deliberately fed at much lower
pressure than the main oil gallery and so can fill with oil sludge enough to
block the flow.

If you are saying the shaft can move fore/aft, then the special locating
screw is loose or fallen out.  This can lead to all sorts of ills, including
what you describe.  ISTR the screw hole also enters the oil passage, so if
the screw is out, the rockers are not getting lubed either.

I think you'd get more benefit from one of those soup can exhaust
extensions.  At least people would be able to see that you're putting on
useless "go fast" accessories ...
