Why do Chevy engines tick?
Lifter tick is a common occurrence in V-8 engines like the Chevy 5.3-liter Vortec. This ticking sound is caused by the valve lifters, which are filled with oil during engine operation. When your engine sits, the oil can seep out of the lifters.

The increased will not only lead to noisy lifters, but it may also increase the temperature a little bit. On the contrary, if the oil is too thin, it won’t provide proper lubrication as well as padding.
What causes a lifter to go bad?
Valve lifters are one of the first components to suffer wear when the oil pressure is consistently low. Low oil pressure can result from a number of factors, including excessive camshaft end play and worn cam bearings, worn oil pump gears, worn crankshaft journals and bearings and worn main and rod bearings.
How do you unstick a lifter?
Fill a small cup with penetrating oil and soak the lifter in it, preferably overnight. Reinstall the lifter and torque the rocker arm to the correct specification. Install the valve cover, using a new gasket. If this procedure does not work, the valve lifter should be replaced.
