Randall: You remark about the external oil feed to the valves, when I
rebuilt my TR4 engine, I found that the rocker shaft had grooves where the
rocker bearings rotated from a total lack of oil over a period of time. I
installed an external feed to correct this. I haven't truly run the engine
except for running in place (tub not installed yet), There is not evidence
of exhaust smoke at this time. Also had the block dipped and decked.
