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 |

Wow, LOTS of useful information. The huge eye opener for me is that compression test have NO RELATIONSHIP to how the engine is really running under operating temperature. All types of cracks in heads and cases proved to also be VERY interesting. I liked how they mapped out the heat ranges of a burnt valve and what they looked like.
Thanks Ken for the info. |
