it could be bent only slightly. if so then a compression test may not reveal a big difference. any amount of rod being bent should show something on a comp test though. though the normal variation of the cylinders could mask it.

on a diesel 1.5 teaspoons of water will fill the combustion chamber. so with a gasser of similar displacement a bit over twice that amount would be needed. so maybe 3.2 teaspoons (or is it cubic inches?). but you get the idea, a full cylinder will not allow the engine to turn over under cranking. so a partially filled cylinder may. anything over the volumn of the compressed combustible material will result in a bent rod of some magnitude.

it is a tricky little question.

good luck
