Other damage like blown cylinders and stuck valves would be nice.
On my presolo final check ride I had a valve stick open. The engine performance dropped and it felt like I was riding in an unbalanced washing machine. It was 110 degrees in phoenix and the density altitude was off the charts. It was a chore getting the plane to climb back to alt (It stuck on throttle up after a simulated emergency decent) so we could land. The whole time oil temp gauge going deeper and deeper into the red. We were only 15 miles from the airport.
Thank goodness it didn’t stick down and blow the cylinder.
Anchor great job getting that one down. I can only imagine how tuff that was.

For those detail nutz like me

--Cessna 172N was the ac.
--Field was KDVT Deer Valley
--Westwind Aviation
--Simulated Emergency Decent was done on AUX1 northwest of Goodyear and North of Luke.
--Didn't declare emergency- Had luke monitoring our progress home and KDVT had cleared us straight in and were aware of our situation.
--Instructor said I handled it well. As soon as the problem hit I yelled it's your plane! and immediatly awaited positive exchange of controls back to him

After he got it back into the climb he gave it to me and told me to redo the emergency checklist he had just done and to land it.
