Ron,
Lycoming lists a variety of fittings in the parts catalog:



4,8 is the standard plug.

10 is called "Adapter, oil cooler connection", #71600. The female thread is 3/8 NPT.

18 is called an "Elbow, universal, 75 degrees". The part number is AN777-8D, so I assume the connection is a standard -8 male flare. You would also need 17 (#71623), 19 (#AN901-8A), and 20 (#71620).

9 is called "Connector, acc hsg to oil cooler inlet hose", #69675. A note says "3/8 flared tube connection to oil cooler". Sounds like just the thing for an accumulator.

Default Ah ha!

Dan,
Thanks for this diagram. So now I see that this is truly an oil access point and not just a thermal oil temp probe assembly point. Can the thermal probe be assembled to this location using one of these fittings? Where does it usually go?

Here is a seperate thread I started today, but it shows the locations of this port on my engine. That seems to be the only logical location for the thermal probe to me.

Thanks,
Brad

Brad,
I've borrowed part of your photo from the other thread. See the hex head plug painted the same color as the case, sort of hidden under the breather fitting in this view? That's the "port C" under discussion.
