[TR] Oil and Rocker Arm Assembly and Adjusting screws

[Tony Drews]

If the spit works anything like the TR-2/3/4, the rocker assembly is 
fed by the oil going to the rear cam bearing.  If the cam bearings 
aren't installed properly, no oil comes up from the cam.  In the 
TR-2/3/4 there's an external line that can be run from the block to 
the head to provide more flow.  On the TR-4, that's where the problem 
would most likely be rather than in the rocker assembly itself.

One way to check is to put the rocker assembly back on the car but 
leave the valve cover off.  Start it up.  If you coat the whole 
engine compartment with oil being flung off of the valve train you 
don't have an oil delivery problem.  If things stay pretty dry, you 
do have a problem.  I'm guessing that others have a better / less 
messy way to check...  :)
