I have an '08 Jima with HW-3 BH,It worked OK for a start,if very jerky,but after a few hours started pouring oil out of the vent on the tank when pressure was released from the valves.I recon it is a simple fix,but after a year of fiddling, I still have not got it working.Is thier a blow up of the valve and check valve so i can see if all the parts are there? Or can someone pick the problem? Thanks Carl
