An unexpected twist.....

The landing light burned out before I could investigate beyond plugging the air vent intakes.

While I had the cowl off to fix the light, I noticed the Scat tube off the muffler muff. Wow and duh!

Amazingly enough, it appears the clamp had not been fastened after the annual last May so the only heat was warm air sucked from
under the cowl and drawn through the plane by vacuum.

Having been raised a Piper driver, I just figured the old girl had a poor heater.

Now the heat works so good I don't even notice the extra fresh air at 25f OAT. There is still a pretty good amount of air coming in
so I suppose the leaks will move back up the list in another couple weeks

Thanks for the help.

Now you mention it, I was going to try a bit of that synthetic steel wool to
keep the bugs out and let air in next summer.

So from the sounds of it, we are assuming my cold air is from leakage around
the vents back in there someplace.

I will try stuffing the inlets tonight. Thanks.

You might have air leaking thru the wing/fuselage joing also. Perhaps
some insulation material around the upper corners of the windshield,
at/near the wing leading edge. You'll have to remove the trim pieces to
get to it, or perhaps the fairing over the wingroot.
