Air Plains, Inc. 300 Horse Engine Upgrade
I recently upgraded my 1976 Cessna 182P with the Continental IO-550 300 horse engine upgrade. I am experiencing heat through the plenum that the Installer cannot figure out. We have made sure that the valves are completely closed but are not certain whether the flap in the heat box is somehow being opened, or if there is another source or issue.
I am curious if anyone else has had the issue or heard of someone else having the issue.
