A few days ago I went flying during one of the colder days this year in ANC (10deg F). I added my second piece of tape to the oil cooler for a complete cover. The previous flight with temps about freezing the oil temp topped out about 145deg during a 2hr duration. The tape helped but still had a hard time getting it to 180deg (topped at 160-165). I’ve noticed condensation in the top of my dipstick if I don’t get the oil up to 180deg during the flight. The other thing I noticed was CHT staying pretty low as well (300-350deg) and rapidly cooling in the pattern as I fly downwind the final. In the pattern the oil temp was as low as 125deg. Not flying a crazy bomber pattern either.
So….I’ve searched the forum and read all that I can find on cub winter ops and I did not see an answer. I am assuming there is not a compression issue(last annual was all in the 70’s).
Has anyone ever added small or partial covers to the cooling intakes on a PA-12/18 with an O-320? I’d love to see pics if you have them. I did hear one guy offhandedly mention he would duct tape his opening.
Thanks
