How much oil goes in the valve compartment on a 1930 GP small bore?
I am starting to re-assemble after re-sleeving both cylinders and installing two valves seats. I know I read somewhere that there was a set amount of oil to put in it but I can't remember where I read it.
Why couldn't a person drill a small passage (say 1/8") in the block at the bottom of the center stud hole. Mine is out right now, the center bolt hole of the cylinders is very close to the oil line feeding cam bevel gears, and then drill a small hole through the center stud. Then in a different location drill a return (1/4") at the proper level to atomatically drain this valve area back to the crankcase. There would be plenty of oil supply available and it would maintain the right height that should be there.
If for some reason it did not work, put a solid stud back in. I'm a machinist and this would be a easy thing to do, then it would be automatically maintained. I know you would not want too much oil in this area but if the drain was the right height it should work.
