A collapsed lifter puts a great deal of stress on a vehicle's valve train, and the weakest link is usually the pushrod. Collapsed lifters can easily bend pushrods, which will subsequently fall out of the space between the rocker arm and the top of the lifter. Once a push rod falls out of the space, the very least you can expect is a dead cylinder.
