Push Rod Lifter Noise at Piper Walton blog

Push Rod Lifter Noise. Hydraulic lifters will normally make some noise when an engine is initially fired up, but should soon quiet down as oil fill the lifters and the lifters expand to tighten up the slop in the valvetrain. The pushrod is one of the few engine parts that are designed without curves as it connects the underside of a rocker arm with the lobes of the camshaft. 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). The most common causes of lifter tick include contaminated oil or not enough of it. Lifter tick in your vehicle stems from issues with the engine's mechanical or hydraulic lifters. Some experts say hydraulic lifters should be presoaked in oil and bled prior to installing them. Engine lifter noise (ticking) a worn or collapsed lifter can create excessive valvetrain lash. Additionally, you might have used the wrong oil. Here's what causes this sound.
