Lifter / Lash Adjuster: Testing and Inspection
VALVE TAPPET - LEAKDOWN TEST, HYDRAULIC
Note: The leakdown test will not be accurate if it is done with engine oil in the hydraulic valve tappet. Use testing fluid. New hydraulic valve tappets
are already filled with testing fluid.
1. Compress the hydraulic valve tappet to remove the engine oil if necessary.
2. Place the (1) hydraulic valve tappet in a (2) commercially available hydraulic tappet leakdown tester. Position the (3) steel ball provided in the
plunger cap. Add testing fluid to cover the hydraulic valve tappet and compress hydraulic tappet leakdown tester until the hydraulic valve tappet is
filled with testing fluid.
3. Adjust the length of the (1) ram so the (2) pointer is just below the (3) Start Timing mark when the ram contacts the hydraulic valve tappet. Start
timing as the pointer passes the (3) Start Timing mark and end timing as the pointer reaches the (4) center mark.
VALVE TAPPET - INSPECTION
1. Inspect the hydraulic valve tappet and roller for damage. If any damage is found, inspect the camshaft lobes and valves for damage.
