It can be the result of designed-in insufficient lubrication or pistons and cylinders that get too tight during part of the warm-up cycle. I would only suspect poor air filtration (FOD) on a certain make/model if occurrences were a function of location, ie more frequent in the dusty Southwest than in the soggy northeast.
