A 1/8 tee sounds familiar to me. Thats a similar setup on the Buda engines 
in my Cockshutt tractors. If you look into that tee it has a very small hole 
in it and I've been told that it is also important in maintaining oil 
pressure. Just working from memory I believe the oil flows from the camshaft 
bearing area through an external line to the tee and from there is diverted 
to the rocker arms and the pressure gauge.
One thing I found out last winter was that if this tee becomes blocked and 
stops flowing to the rocker arms they will eventually get rather noisy. 
Cleaning out the tee fitting restored the engine to its former silent 
running and hopefully no permanent damage was done.
