Gamijectors - problem probably solved

The problem the lubed cam solves is the delay in splash lubrication

A better way out of this is to religiously preheat in cold weather.
The cam won't ever drain completely dry. Rather the problem is that
it takes quite a while for the replacement lubrication fog to develop
in a cold engine/crankcase.

Think of it this way - many of the the most critical parts of an
engine are lubricated only by the fog. The design of the oil pump and
relief valve system is such that the sump oil has little access to the
heat of an engine if the oil is thick. As a result, the fog can be
very slow to develop. Any high power without having the fog, & the
cam can spall in a few seconds. It will never recover its surfaces
from this.

Pre oilers might help, but there is thermally a long way between a few
oil splatters and a true oil fog. The problem really isn't the
immediacy of oil pressure, it is the needed thinning so that oil is
generously spraying around the crankcase vs being congealed.
