Birds Nest Under LIVP Cowling: Higher
CHTs
After a trip to the midwest, I noticed much higher
cylinder temps for the rear cylinders during climb and cruise. I
pulled the cowling and found a bunch of Nebraska weeds and vegetation
stuck and stuffed on top of the rear cylinders (#2 and #1), which
certainly would have impaired cooling back there.
I almost think of it as a birds nest (blown to
smithereens), but the airplane was hangered (not exclusively
protective of birds), but was pointed towards the outside while the
hanger was open during the two days.
I'm reminded that birds only need a half hour of unattended time
to stuff a bunch of nesting material inside the cowling.
This is the season for birds nests. Look more carefully
than I apparently did.
Lucky there was not a small fire under the cowling.
