True enough. But if it's reliable and sufficiently generic, it might serve Lycoming owners (of which, sadly, I am one) well. As you are probably aware, one of the more interesting features of Lycs is the front seal, which has a nasty habit of "falling out" at irregular intervals for reasons best known to itself (most recent example: just a few hours TTSN). Major thread around that on the Cozy list as we speak. The problem is aggravated with pushers since we have no way to detect the failure until the oil pressure goes to zero, and that's pretty late in the game.

What's it look like? How does it work? How is it installed? ... Jim S.
