Mark said, "it's the cylinder walls rusting, especially in a humid outside environment like an airplane lives in. Valve guides don't worry me at all...they are barely lubed at all, . . .
Mike: In squirting oil down the guides it would be for the purpose of lubing the lobes, not the guides. There's so little clearance I doubt I'd get much down there except doing it daily over two or three days before I start the engine, is what I've intended. Mark, "As for the oil pump, it's worth noting for taildraggers flying behind VW engines . . . . Mike: Since day one I've always had a rolling office chair with blankets on it setting underneath the tail of the KR, to keep it level as it sets. This is not only useful in getting a more complete drain when changing oil, but also induces oil in the rocker areas and everywhere else to drain straight down, evenly, instead of pooling at the back and bottom of the engine. It also keeps the pump immersed, along with the front of the crank and to some unknown extent, the camshaft. Another couple advantages to keeping it level is it's easier to work on, both engine and interior of fuselage. Even for tire changing - sitting on jackstands in a level position it's always seems more stable than if tail down. Tri-gears don't have these concerns of course. If there's a choice on something, I'll try and think which one is better.
