How To Clean Hydraulic Valve Lifters?

Cleaning hydraulic valve lifters is an important maintenance task that helps ensure proper engine performance and reduce noise caused by dirt or debris buildup. Here’s a step-by-step guide on how to clean hydraulic valve lifters:

1. Gather the Necessary Tools and Materials:
   • New engine oil
   • Clean rags or towels
   • Engine degreaser or parts cleaner
   • Small brush or toothbrush
   • Plastic container or tray
2. Preparation:
   • Allow the engine to cool down completely before starting the cleaning process.
   • Remove the valve cover or covers to access the hydraulic valve lifters. Refer to the manufacturer’s instructions or a repair manual for your specific engine to locate and remove the valve cover(s) properly.
3. Removal of Hydraulic Valve Lifters:
   • Identify the hydraulic valve lifters in the engine.
   • One at a time, carefully remove the hydraulic valve lifters from their respective locations. Depending on your engine, you may need to remove other components or parts to access the lifters.
   • Place each lifter in a plastic container or tray in the order they were removed. This will help ensure they are reinstalled correctly later.
4. Cleaning the Lifters:
   • Pour a small amount of engine degreaser or parts cleaner into a container.
   • Place one hydraulic valve lifter into the container, ensuring it is fully submerged in the cleaner.
   • Allow the lifter to soak for the recommended duration specified by the cleaner manufacturer. This usually ranges from 15 minutes to an hour.
   • Use a small brush or toothbrush to gently scrub the lifter’s exterior surfaces, removing any deposits or dirt.
   • Rinse the lifter thoroughly with clean water to remove any remaining cleaner or debris.
   • Dry the lifter using a clean rag or towel. Ensure there are no traces of moisture before reinstallation.
5. Reinstallation:
   • Apply a small amount of fresh engine oil to the cleaned lifter’s exterior surface.
   • Carefully place the lifter back into its original position in the engine, ensuring it is properly aligned and seated.
   • Repeat the cleaning process for each hydraulic valve lifter, following the same steps.
   • Once all the lifters are cleaned and reinstalled, make sure they are secured properly.
6. Reassembly:
   • Reinstall the valve cover(s) according to the manufacturer’s instructions.
   • Double-check that all components and parts are properly secured and tightened.
7. Test and Inspection:
   • Start the engine and let it run for a few minutes to ensure proper operation and to allow the lifters to refill with oil.
   • Listen for any abnormal noises or ticking sounds that could indicate further issues.
   • If noise or performance problems persist, it may be necessary to consult a professional mechanic for further diagnosis and repair.
