Cheaper than a gasket kit and alot of satisfaction knowing alls well. -------Original Message------- > From: "Paul" > Subject: [FlyRotary] Re: Engine damage thoughts > Sent: 19 Dec 2004 04:30:19 > > Hi, Rusty....I have found that oil analysis really tells all. They can tell if there is anything in the oil and will even tell you what it was from (bearings, bronze from bushings, etc, etc). Also found that cutting into the oil filter will tell you almost everything you need to know, although not quite as scientific as engine oil analysis. We used to send our oil to the Fram filter company, and they would send back a report that would alert you to any potential problems. Just a thought.

As soon as the oil started to leak, I pulled the engine back to idle, and descended ASAP. I'm sure I was doing at least 2000 fpm from 6000 to 2000 ft, which only accounts for 2 minutes of time. At 2000 ft, is when I tried to throttle up, and the engine quit, so no time after that counts. I'm absolutely sure the engine quit because I had the mixture knob set way lean for cruise, and not because it seized up. > > This means that at worst, the engine idled for 2 minutes with no oil pressure. My guess would be that it was more like 30 seconds or less. With this in mind, I'm thinking that it's worth doing some ground runs of the engine to see how healthy it seems. If I can thoroughly run it on the ground without problems, then I can follow that with about 10 hours of circling the field. By that point, I can't imagine having any further concerns. If there was a problem, it would damage the engine further, but still continue to until I made it to an airport. If I'm wrong about how much damage there might be, it will get expensive, but shouldn't be life threatening. > > Many of you have a lot more experience with these engines than I do.
