Hi All - My RV-10 with a Lycoming IO-540 has been a dependable steed for a number of years, acing most of her condition inspections with only minor squawks. I recently noticed a small oil puddle that would form behind the nose wheel fairing after flights. I do my own oil changes, but I definitely need an A&P to look at and fix this. The diagnosis was that the leak was coming from a seam of the oil pan. See this pic: https://photos.app.goo.gl/Mm36FV1QEECAkD1XA . The recommendation is to tighten the through bolts and apply epoxy. My understanding is that epoxy was applied to this location previously and presumably wore out (or the seam gap is getting larger). The alternative fix is to remove the engine, put it on the bench, and do a more permanent fix. Have folks seen this issue before with Lycomings? Does this sound like a good course of action? This is a new maintenance shop that I'm using, so I was interested in the perspectives of Vans builders. Thanks for any information you can provide.
