Rocker shaft oil journal

I just bought a w-9 whaich I have been working on getting up and running. When I was setting the clearance on the valve tappets, I noticed that the rocker shaft assembly was dry. When I ran the tractor with the valve cover off, no oil came up. Tonight I removed the head to see if there was a clog. What I found is that someone had filled the oil journal that comes up from the crankcase with a silver putty that contained steel fibers. I had to dill the putty out with a 1 foot long 3/8" drill bit since the putty filled the journal all the way down to the crankcase. I finally did get oil to come through the journal by turning the engine with the started motor. My question is way would anyone ever purposely fill this journal?
 
Found something like that before and hope its not the problem. Engine run for a time with bad main or cam bearing or bearings. Sometimes it will coat the oil drain back areas with a silver collor. Can get kind of pasty if conditions were right.
 
If there was an external oiler on it to make it happen, it could be, but just shade tree all the way. Jim
 
Did you pull the oil pan to see what was in it? Maybe somebody poured something in it at one time for some reason and it went thru the oil pump and solidified in the passage.
 
That does seem possible. Flakes of bearing material being packed into the passage. However if the bearings are OK, and no drama, I would go forward with running it. If the pan was full of metal, I would not!! Jim
 
Sounds simular to my super m problem, no oil to the top. Block was cracked through the center cam bearing,bearing spun and I put a junk yard motor in it. That whole center cast iron web in the center of the block was cracked, didn't expect that.
