style="FONT-FAMILY: 'Verdana','sans-serif'; FONT-SIZE: 10pt">The Good: I
finally got out to fly today and put up flights 6 and 7 for the
season.<BR> <BR>The Bad: To say I practiced flying the Masters
Pattern might not hold up in court. It had looping segments (of various
radii), straight lines (some of very, very short length), roles (lets talk about
mortgage rates instead); in other words, it had all the basic elements. It
also could be argued that I was flying the Wonkavator, up ways and down ways,
sideways and back ways and slantways......<BR> <BR>The Ugly: 5
minutes into flight #2, the engine stopped. After a fun crosswind glide, I
took the engine apart at the field to find the crankshaft-piston area very
dry with shaving's everywhere, a mashed and bent (sort of) connecting rod, and a
damage to the rotary valve. I need to take pictures and post them because
I have never seen damage like this. It looks like lubricating oil was
unable to get into the region and the engine just ate itself.<BR> <BR>This
was my 160DZ and is on the heals of breaking the shaft that supports the rocker
arms on a 140DZ suddenly a month or so ago. Is there something wrong with
the lubrication system on these motors due to some kind of blockage? Any
suggestions on what to check would be appreciated. The engines all looked
clean and free of and kind of FOD when I took them apart and re-assembled them
this late winter/early fall. Before I go killing my last 170DZ, I am open
to what people think I should look for (beside an OS, going electric, or
gas).<BR> <BR>Mike Cohen<BR>D4<BR> <o:p></o:p></SPAN></P>
