Therein is a beautiful V35 Bonanza with a 300 hour millenium engine that swollowed an exhaust valve. Seems as though the pilot owner typically flies lean of max EGT because he has an analyzer. His most recent flight from Colorado was a flight with a rough running engine. Upon inspection of the plugs and other various and typical inspections nothing could be found.. The owner/ pilot decided to taxi down to the runnup area and do a few pattern rounds to "Check out the plane". On runnup it ran rough, so he called the A&P on the cell phone for hints. Then, Then he said, "Don't bother, send the tug. Something went bang and I need a tow back to the shop." He is one lucky man to be alive and still has his plane as well minus a severely damaged New!!! 300 hour engine. I saw bits of metal and a dropped valve into the cylinder, as well as mangled valve keepers. My A&P back in Washington told me,(regarding running lean of peak). You can pay more for gas, run rich of peak or pay me a lot more for new cylinders and other parts in an overhaul. After spending your kids inheritance on those wonderful flying machines; why do guys think they can cheat the laws of physics and the grim reaper?
