Different year 235 motors pull rocker oil off different parts of the
internal oiling system (there were several design changes of the rocker
oiling system during the course of production for 235/261 engines). Several
model years pull oil off the rear cam bearing, some models pull oil off one
of the center bearings (crankshaft or cam - one of the two). If there is no
oil on the crank/cam, then there will be no oil on the rockers. However,
given that you have oil pressure at the gauge, it stands to reason that you
either have a clogged system (probable) or you have the rocker oilers set up
(possible). I sent most of the 235 rocker oiling diagrams to Rob J. several
months ago. He is now the de facto rocker oiler expert and will have to
chime in when he gets out from under his hood (and you'll need to know what
year your motor is).

WRONG ... you should have oil coming up through the rocker arm oiler
just by spinning the oil pump using the drill and screw driver method
that I told you about. It has nothing to do with the oil "building up
on the crankshaft. In fact it is almost standard procedure to prime
your engine oiling system using this method before actually starting an
engine after a rebuild.

I talked with the shop who did the rebuild and they said that oil will not
come out of the little holes unless there is a build up of oil on the crank
shaft. Does this sound right?
