Bill3558 Posted August 17, 2023 Report Share Posted August 17, 2023 Saw this on the you tubes. Anyone here use it? No more replacing the copper gasket. Will safety wire it into place. I’m thinking I can attach a tube, open the valve, and drain without removing lower cowling. Thoughts? Quote Link to comment Share on other sites More sharing options...
Garrett Gee Posted August 17, 2023 Report Share Posted August 17, 2023 I use something similar, but it was from aircraft spruce. It is the CURTIS OIL DRAIN VALVE FOR ROTAX. About double the price though. I installed a copper crush washer, valve, and safety wired, and has been trouble free. Can't speak to that specific one, but I would go with something from a company like Curtis, as they also make drain valves for the "certified" world. Also has a nice long stem for attaching a hose if you want. Edit: I can make it work without removal of the lower cowling, but usually end up fussing about my arms, as I either burn them or cut them trying to get to the valve.

Tom Baker Posted August 17, 2023 Report Share Posted August 17, 2023 I rarely remove the plug, I remove the tank and clean the inside. There is alway sludge on the bottom of the tank that needs cleaned anyway. Quote Link to comment Share on other sites More sharing options...
Roger Lee Posted August 17, 2023 Report Share Posted August 17, 2023 Rotax doesn't like oil drain valves. They drain toooo slow and you get a poor flush on the tank debris. Pluse they worry about leaking. Quote Link to comment Share on other sites More sharing options...

Almost every piston engine flying has them and has for the last 75 or more years. Quote Link to comment Share on other sites More sharing options...
procharger Posted August 17, 2023 Report Share Posted August 17, 2023 I have changed oil several times without replacing drain plug ring never had any leaks, I keep spare gaskets or rings just in case. Quote Link to comment Share on other sites More sharing options...

Per Rotax, and standard aviation practices it should be replaced anytime it has been removed. Quote Link to comment Share on other sites More sharing options...
Anticept Posted August 17, 2023 Report Share Posted August 17, 2023 I've been using drain valves for years and years, and the bottom of the reservoirs might have a little film at most. Big important thing is you get it HOT before you start changing oil. I mean 160+ hot. Hotter is better. It drains like water. Quote Link to comment Share on other sites More sharing options...
procharger Posted August 20, 2023 Report Share Posted August 20, 2023 Never had any sludge in my oil tank at all 93 mogas only. Mobil 1 4T motorcycle oil. Quote Link to comment Share on other sites More sharing options...
