What do I do if my Chevy Silverado makes a ticking noise?
Once the noisy cylinders have been located, the head will have to come off next. This involves removing the intake, exhaust manifolds, rockers and stands, sensors and wiring, accessories, etc. Actually it isn’t that bad of a job to take one of these engines apart, and I always do this with the engine still in the truck.
What is the lifter tick on a Vortec 8100?
Vortec 8100 Lifter Tick. Another problem common amongst a lot of the vortec engine line is lifter tick. Lifters sit on the camshaft and are responsible for the opening and closing of the valves. The lifter pushes the pushrod into the rocker arms which is what then forces the valve open.
Why is my Vortec 8100 having engine problems?
Because the speed of the crankshaft is one of the most important variables in engine timing, a bad sensor can lead to significant performance issues. When a sensor goes faulty, it relays incorrect information to the ECU which then incorrectly alters engine timing.
