| Subject: | Any interest in four Millennium O-320 narrow deck cylinders? |
--> Glasair-List message posted by: MPPalmer@aol.com
We're coming up on 2000 hrs on a set of first run Millennium cylinders on our
Glasair. I'm told they hold up well and will go another 2000 easily after
overhaul.
Am trying to decide what to do - keep them or buy new. Part of the decision
equation involves finding if anyone is interested in buying our old
Millenniums and for how much. These are narrow deck jugs, for the 160 HP Lycoming.
AFAIK, no cracks. Compression has always been good, although starting to drop
off gracefully as they age. We upgraded to 9:1 pistons, so you make a little
more power. They've been babied all their lives, with long cross country
flying, very few touch 'n' go cycles, and smooth (starting from 60 to 90 mile out)
power reductions.
Max temps have been in the 425 on climbout, with the exception of #2 which
saw 450 occasionally until I discovered the baffle had been designed wrong. For
the past 300 to 400 hours, we've been running LOP, with CHT's in the 300's in
cruise.
What else would you like to know about them? I've bore scoped the valve
faces - look good to me. Never a stuck valve (changed oil every 35 to 40 hours).
I point out that someone like Gibson says they can yellow tag them for $300,
assuming nothing broken.
Please let me know,
Thanks,
Mike Palmer <><
