Awhile back I installed the Anti-Splat air/oil separator. Last fall I got a packet from them regarding a AD, indicating the exhaust valve should be checked for coking, and a “emergency bypass” that they sent me be installed in case the exhaust valve become blocked. Apparently an RV-10 was forced down as the engine stopped due to such a blockage. This spring I decided I should go ahead and inspect my valve. This is what I found. It’s quite a bit more than I expected to find, based on how many hours we’ve flown, but wasn’t alarming to me.

    […] We’ve had a couple of squawks I’ve wanted to deal with for a bit, well, at least one, Cylinder 3’s EGT had gone dead. That turned out to be just a loose wire, though I replaced it anyway. Second, I wanted to upgrade our air oil separator to the AntiSplat based on recommendations from our friends, which you can see the details of which here. Finally I wanted to reconnect the copilot throttle so I can more easily practice from the right seat while I wait for Dave to come up and finalize my transition. Since we had a long weekend, and Dave could be here as early as next week, I knocked these out. I’d forgotten how sweaty I can get, with this being one of the first really warm weekends of the year, but I was able to get all of these knocked out easily and still get some relaxing in. Can’t wait to go flying. [UPDATE: Later we were advised to check this…] […]
