Oil Cooler on the Lockheed 12 

Great find! Love your videos. Great radio calls Jacob.

Always a joy and a pleasure to watch your updates. Thank you very much sharing.!

Cookies 🍪 in yer belly! Great video, and seeing you working things out!

Screens out on the front may be a great idea. That was really cool to hear little man on frequency getting him some stick time. My father is still talking about his ride in your Lockheed 😁 It was really appreciated you taking the time to share your aircraft and fuel to make memories for others.

Apparently keeping those coolers clean will work. Screens for the cooler intakes.

Like your pre flight routine. Next time throw her around a bit for the Italy tune up!

Maybe some type of custom bent vacuum hose to regularly clean coolers if screen is an issue.

Boom!

Nice trouble shooting, can you reach inside duct to oil cooler face n feel for debris ? Beautiful acft.

The screens might still get full of debris but at least it would be so much easier to clean them off each time and that would become part of your preflight inspection as well. Could it be that the direction of prop rotation could cause one side to gather more grass than the other side? Just a thought.
