Lycoming recognized the problem and probably has recognized it for a
long time, and designed a fix for a particular engine used in the
Mooney. I think it's an O-540. This fix involved routing external
oil lines to the cylinderheads to bathe the valve stems. But they
made the fix for the Mooney only, claiming that the baffling was too
tight and that the Mooney installation promoted a hot engine. The
problem with this is that Mooney consulted with Lycoming on the baffle
design, again, according the the two mechanics. . .

Corky.........

I seem to remember when Ford first came out with their OHV V-8 in 1954, they
had a problem with the rocker arm shafts wearing out quickly. This was due
to a lack of oil feed to the valve train and could be solved by the addition
of a "Top-Oiler kit".

Not that this has any to do with auto-conversions or Lycomings. You just
tweaked my memory. :-)
