Looks like I've got an oil leak in my 550 hr SFNEW IO-360-A3B6
Lycoming engine. My mechanic says I should clean the engine and see
where its coming from. I feel strange cleaning the engine. He said to
use an automotive engine cleaner and then wash it off right away. I
guess its not different than flying through a level 5 rain shower but
I can't see spraying my mags down with a hose. How do most of you do
it?
