Were praying for all our friends out at Sun n' Fun. We're seeing a lot of bad weather down here, reports of a tornado, damaged buildings and aircraft.http://www.theledger.com/apps/pbcs.dll/gallery?Dato 110331&Kategori=PHOTOS51&Lopenr=331009999&Ref=PH&pl=1Pictures;http://www.theledger.com/apps/pbcs.dll/gallery?Dato 110331&Kategori=PHOTOS51&Lopenr=331009999&Ref=PH&pl=1" target=_blank>http://www.matronics.com/Navigator?Piet ... ______Date: Thu, 31 Mar 2011 15:44:56 -0500Subject: Re: Pietenpol-List: Storms damage Piets

Someone asked off list what was wrong with my heads. Here's a quick update: Iposted here a few months ago that I noticed a power drop last time I flew theplane. Brought her home successfully. Went through the troubleshooting stepsWilliam Wynne helped me develop. Bottom line - no compression in #3 cylinder.Pulled the heads and found the exhaust valve missing a chunk. Pulled the otherhead, too, based on differential compression numbers. I'm no expert, butI think I was about to trash a valve on that side as well - another exhaust valvewas looking rough. I sent the heads to get reworked at Roy's, one of William'srecommended shops. They're back and they look great. Roy said that theexhaust guides were shot and that the valve spring pressures were out of tolerance.He believes that the incorrect pressures (too low) prevented the valvesfrom closing tightly and dissipating heat the way they should, likely leadingto the burned valves.I had the heads done at a car shop many years ago, before the state of the artin head work had advanced to its current state. If all the recommended vendorsdo head work like Roy, we should be in pretty good shape.Next steps: install 5th bearing, reassemble motor, fly.--------Kevin "Axel" PurteeNX899KPAustin/Georgetown, TXRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Storms damage Piets

That picture made me physically ill. Words can't express my sympathy. While outsidersmay see 3 damaged planes, I can only see the thousands of hours of blood,sweat and tears that were poured into those beautiful machines. The reportI saw from EAA was that there were no significant injuries at the site itself.I thank God for that and pray for the health and safety for everyone in thearea.--------Gary WilsonGreenville Wisconsingtche98 (at) gmail ((dot)) comPlanning PhaseRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Thu, 31 Mar 2011 21:16:45 -0400
