Hi all, I need some help with a minor problem. The other day I found that one of my intake pipes was loose in the flange and was leaking (I have a Lycoming O-360A4M). I thought I'd replace the gasket and that'd be it. However, when I pulled it, cleaned everything and tried to put it back together, it turned out that the pipe is actually recessed in the flange. Not by a lot, maybe just 5 to 10 thou, but it's enough so that it is loose in the flange when everything is tightened up with a standard 71973 gasket. I think the gaskets that were there originally are thicker and more compressible, which is why it was fine. I pulled two other pipes and they are all the same way.
Now I'm pretty confused about how this happened. Is it a different part somehow? Or do they wear out this way? The engine was field overhauled 1100 hours ago, and I'm not sure about its history prior to that.
Also, any advice on what'd be the best way to proceed? I can buy new pipes and flanges are replace them all. This is the only idea I have, are there other options?
Thanks!
