A buddy of mine who has his own plane sent this link to me knowing I would find it interesting due to the great similarities between air-cooled aviation engines and the ones in our cars.
It is long, but very informative. Touches on burnt valves, cylinder/case cracks, etc. Teaser - the first 15 minutes or so explains why compression tests are close to worthless. https://www.youtube.com/watch?v=4NnOYvOlMB8 |

What he is talking about is a airplane going through a annual inspection that requires a compression test even though the engine is running fine, in order to find any potential problems before a failure in mid flight.
This is not the same thing as using a compression test to diagnose a automotive engine that won't start or is running poorly. Or just to check the overall health of the engine. |

(IMG:style_emoticons/default/agree.gif) but if you watch the video, you will learn a hell of a lot. On the surface, aviation engines are far different in that if they fail, things fall from the sky and kill people. However, the vast majority of what is covered in the video is applicable to our engines. |
