'72 FJ40: ongoing F-engine, frame off rebuild
After re-building the engine in my 72 FJ40 that had been sitting around for the last thirty years, I don't have any oil making it up to the top of the cylinder head where the valves and rockers live. I have a 9/72 FJ40, or more specifically, early to 9/72 (no fuel door); and the original block F-engine runs pretty well except for no oil reaches the split rocker shafts through the copper (now steel) tube. An oil pressure gauge attached to the sender unit port reads 60psi when cold and carb is choked off and falls to about 45 when engine idles warm.
I removed the engine side cover, detached the vertical steel feeder tube, and removed the tube fitting threaded into the block at the second camshaft bearing. When I look down into the threaded hole above the second camshaft bearing where the feeder tube used to be, I can see that the hole in the second camshaft bearing lines up more or less with the feeder tube hole. Well that's good, but when I turn the crankshaft I never see the thru-holes in the camshaft line up with the bearing hole. I think this explains why I have no oil up top but why can't I see the camshaft holes? My first thought is that the camshaft is shifted front-to-back or maybe my "new" camshaft is missing the holes all together. Anyone else have a similar experience?
