What does it mean when a valve clatters in a car?

EGR operates when conditions exist that cause pinging or valve clatter. A valve opens and circulates exhaust gas into the intake manifold to cool the combustion process. Exhaust gas is very low in oxygen. Adding exhaust gas to the fuel/air mixture, helps lower cylinder temperature.

What’s the difference between pre ignition and valve clatter?

This occurs on acceleration with the engine under a load. Each term describes a slightly different con dition, but the result is usually the same with each, engine damage. What is pre-ignition or valve clatter? With pre-ignition, the fuel/air mixture in the cylinder spontaneously explodes, slightly before the spark plug ignites it.

Where does the clickety clack come from in an engine?

Most everyone who has owned a car has heard a clickety-clack coming from under the hood. The most common of such sounds emanates from the valve train of the engine. Some engines have rods pushing up on one end of rocker arms that push down on valves. The rods ride on cam shafts whose lobes time the valve movements.

What kind of vibration does a GMC Sierra have?

I previously owned a 2013 GMC Sierra 1500 with a 6.2 l engine that developed a vibration after approximately 20000 kms. the vibration was mainly at speeds over 100 km per hour and at 110 km sometimes it would almost make the truck uncontrollable!

What kind of acceleration does a GMC Sierra have?

Alright I’m going to do the best I can to try and describe what is going on. I have a 2005 GMC Sierra with the 5.3L H.O. 139K. The truck starts and idles without an issue. Durring light acceleration and at low speeds (city driving 35 mph or so) the truck seeems to run fine.
