Importance of good baffle seal

FYI for those guys complaining of high CHT's you might want to have a good
look. Have a local guy here with an O-320 in a Luscombe that has been
removed and shoved engine back up the overhaulers @$$ 3 or 4 times in the
last year and a half.... telling him he did a shit job on the overhaul. Case
has made trips to ECI, cylinders have been redone twice etc and still
running high. One of our chapter members said to him last week.."you really
should take that ratty baffle seal off and put some new stuff on...it sure
might help". When he finally gave in and listened the CHT's dropped ONE
HUNDRED!!! degrees F! Makes you wonder if any of the nine or ten thousand
dollars in extra work and a year of aircraft downtime (and the fun of
pulling a motor on and off using a tripod on the beach!!) and tinkering
actually did anything.

Cheers,
Wayne
