Lycoming Galley Plugs

[Tommy123]

I had same problem years ago, plugs were removed during case overhaul, were not installed. I got the accessory case off the plane in a Mooney e model. Can be done.

A borescope of some kind could help determine if the plugs are installed - through a mag hole? I don't know if this was an issue for you, but I can see how overhauling an engine over a long period of time could be problematic. Would you remember at the end of 2 yrs what you did in the beginning, vs if it was a week ago? Anyway, you will remember next time

After some hunting around with the borescope through both mag holes, I determined that I had indeed missed one of the three plugs.

Here's the left one that I installed during the rebuild:



Here's the empty hole on the right side:



After a doomed attempt to get the plug in without pulling the accessory cover (there's a bit of space in there to work, but the angle is impossible), I pulled all the accessories and then removed the cover. Turns out there's plenty of room on the RV-4 to do this once you remove the accessories.

Here's the plug properly intstalled on the right side.



That was a far as I could get this weekend. Plus I had to order new gaskets. So next weekend I'll put everything back together and try again.

Thanks,
