I was getting ready to ask about the tin primary as Ron did. Does it still have that or is it alloy also?

I am not an expert but understand that the pressed steel was used on the military bike (3HW) and the alloy one on the civilian version (3H).

Ron, Thank you very much! I will check per your recommendation. Regards, Paul

I am new to this forum. Lots of interesting information here... I have owned a 3HW for a number of years an continue to fight a significant oil leak. When it sits for any period the oil drains from the tank into the engine and eventually finds a way out to the floor. When I bought it someone had put a valve in the oil line running to the engine which I assume was to fix this particular issue. I have removed the valve as I am always afraid I will forget to open it before riding the bike! I have had the engine apart but haven't found any particular reason why the oil should drain this way. Anyone else had this issue or have any ideas to address it? Thanks in advance!
