Back to airplane stuff.
Heres an old timers trick.
Had a pilot mayday into our airport. Loss of oil pressure and shaking engine. Owner called it a loss and got paid from the insurance. A buddy of ours got it from the insurance company for a low low price.
So we pull it apart and find one connecting rod had broke, left the piston in the jug and self clearanced itself.
Heres the crank damage on that one.
That crank is toast.
So our buddy buys a complete used engine for parts. Have 2 make 1.
Today is checking this other crank to see if its in spec or not.
It had spots like this.
Got it polished out and mic'd everything.
It passes.
So now we proceed to rebuild this continental O-300.
Cam and case halves will be in the next few days.
Then we have 11 jugs to clean, inspect and measure to see if we can get 6 good ones.
