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 |

Interesting bit, but in respect to his "compression" test discussion, he is talking leak down which is what is performed during aircraft engine inspections, but is typically referred to as a compression test in the aviation world.
As for basic compression test in the auto world, I've never had one not indicate a true problem be it rings, burned valves, or just a simple valve adjustment. As for leak down, I don't have much experience there... |
