Here's the email Randy just sent me back.
Marc,
The oil comes up thru the pushrod and into the rocker via a small oil hole
drilled in the adjuster. We then have a groove in the rocker the oil can
travel around allowing some to flow out to the roller tip and the rest is
used to lubricate the shaft. Most important is the pushrod length so that
the oil hole in the adjuster lines up with the oil hole in the rocker to
allow for the oil to flow. Hope this helps. Let me know if you have any
other questions. Thanks.
Randy Becker Jr.
So I'll take them apart to see all that as soon as I get a chance.
