Jim I have never heard of an engine quitting due to detonation by itself. If the engine quits is is usually due to the engine damage done by the detonation, not the detonation itself, if that makes sense. Most often the damage is to the crown of the psiton, since detonation is usually accompani

Colin: When I had my engine failure in a Cardinal in '71 I was told that over-heating results from flying it to lean and that became an issure because about 15 min before my problem developed I let down from 10,500 to 8,500 on a trip from Prescott AZ(PRC) to Santa Ana CA(SNA) at the Colorado Ri

KR> Detonation as crank failure cause?

2008-10-12 Thread Mark Jones
No one has mentioned anything about detonation of the engine as a factor in crank failure. Detonation causes undue stresses on a crank by creating a hammer like force generated from the piston through the rods to the crank. This hammer-like shock wave being imposed on the crank causes severe ove

Detonation can certainly cause some bearing damage, but it would have to be quite severe and continuous to break a crank. I've torn down an engine subjected to severe and constant detonation (mistimed ignition timing due to a slipped harmonic balancer in a boat). It looked like someone had wo
