What Does A Collapsed Lifter Do. The extra clearance typically results in a ticking or tapping sound that has a frequency lower than engine rpm (because the valvetrain operates at half of the speed of the crankshaft). A sticky lifter remains in a collapsed state instead of going up and down. If a customer brings their vehicle to a gm dealership and reports a valve lifter problem, the dealership will first determine whether or not the customer has experienced a previous valve lifter issue with this particular vehicle. A collapsed lifter is usually caused by debris or sludge buildup in the engine or a malfunctioning lifter. A worn or collapsed lifter can create excessive valvetrain lash. When a lifter collapses, it means the camshaft isn’t opening high enough, and the valve is opened for a shorter time. Bent pushrods can fall from the space between. When the lifter doesn’t move, the system becomes unable to maintain oil pressure. Collapsed lifters put a lot of additional stress on the valvetrain, particularly on the pushrods, as they are the weakest link. If a rocker arm or pushrod controls the lifter’s position, it can cause lifter failure. It will also lead to the lifter’s internal parts hammering against one other, generating more noise.
