Started her up after finishing main wiring and she burst into life. = (without prop at the moment). ~70psi oil pressure oil and water temps building. Ran it for 5 mins or = so before shutdown not wanting temps above 200. We worked out that if we lifted the tail up we could get some more air = out and water in. I have some questions/concerns: 1. Gurgling sound emanating from oil filler/breather with white = substance on the oil dip stick. Concerned water may be getting into = sump. What are the symptoms of o-ring failure? So much to learn re = rotaries. 2. If we do need to tear it down, any great sources of how to go about = it. Remembering years ago seeing Bruce T had a video? 3. We are working on an expansion tank design and wondered if someone = could share the important elements of a good cooling system design. = Looking at photos of other aircraft I=92ve seen lines to expansion tanks = from A. Rear iron port. B. Radiator tank top. etc. A. Is height of tank = significant? B. Volume required? C. How much air should be left in the = tank? D. Cap style?. So much appreciate having this list.
