Review on EZ Oil Drain Valve Removable Replacement Parts best: Engines & Engine Parts by Duy Desperado

I had to modify the frame to make the valve work. The valve body was too big for the gx390 engine. A 12mm fiber disc solved this problem. . The valve didn't seem to drain the water properly without tipping the machine. I drilled a 3/4" hole in the frame for the 90 degree adapter. It's dripping great now. Obviously this isn't plug and play for Honda gx390 engines. Obviously this will void any warranty. Gave three stars , because I had to change the settings to make it work.
