I'm hoping someone can shed some light on a "problem" i'm having with my 325R5 radial, namely excessive oil coming from the crankcase drain nipple. I have a silicon tube attached so I can see the flow.Not just drops, but a steady dribble...
The engine only has a couple of hours run time on it, mostly on the bench in the past few weeks. It sat for about 8 months after a maiden flight crash :-( so I'm concerned that there may be something rusted inside. Could it be the rings?
It hand starts, idles and revs hard, all cylinders firing, no problem. I've twiddled the needles but it wasn't like this last year...
I also have a 200R3 powering a 68" Su-31, with nothing more than the occasional drip from the vent.
Any suggestions / ideas will be welcome.
