(manuel weber) ________________________________ Message 1 _____________________________________ Time: 05:21:13 AM PST US From: "Ralph E. Capen" Subject: LycomingEngines-List: Engine - which drain plug port to use? Folks, I'm getting ready to put some 'real' oil in my engine prior to starting it up instead of the pickling juices from the builder. I'm thinking about maintenance - I'll need to change the oil on a regular basis so I got one of the drain valves from ACS. The question is where to put it....there are three places that are available and lend themselves to easy access. Some a re Left, some are right, some are forward, some are aft. Two of them are safety-wired with a square looking bolt head protruding, one of them is a recessed allen-head plug (with no safety). I'm thinking that the safetied ones are straight thread vs NPT which would narrow my choices as I think my fitting is NPT. The aircraft is a 6A so it sits more level than a 6 - that would be a consideration.

The plugs that are the choices are either LH or RH sides. In your case, the ones that you mention are safety wired. They are both NTP threads. Either of these is the correct position for a drain.
