Remove the old valve cover gasket with the scraper and solvent. Once the valve covers are clean, apply the new gasket and seal them with gasket sealer. Use a torque wrench and tighten the valve cover bolts to manufacturer specifications.
When do hydraulic lifters start to wear out?
After several years of running the engine of your vehicle, the hydraulic lifters within the valve train can become laden with sludge, and other contaminants in the valve, that they start to wear out. New hydraulic lifters can make a tremendous difference in the way that a vehicle runs as well as how the engine sounds.

What is a valve lifter and why is it important?
Smaller, overhead cam engines, do not use pushrods, and therefore do not have valve lifters. A hydraulic valve lifter is also called a hydraulic tappet. Many years ago, in flathead engines, mechanical valve lifters actually pushed a valve upwards. The name stuck, but these days, the valve actually moves downwards.
