SYMPTOM/CONDITION:
Some vehicles may have a condition where the valve train makes a ticking noise similar to valve lifter noise, but not as loud. This noise is heard in a fully
warmed engine between 500 and 1000 rpm. The ticking noise will disappear as the engine rpm is raised above 1000 rpm. Customers may describe this
condition as lifter noise.
DIAGNOSIS:
Drive the vehicle to warm the coolant and engine oil fully. With the engine at idle and the hood open, listen carefully for ticking noises coming from the
rocker covers. Raise the engine rpm and listen for the noise again. If the noise is heard at idle but not at higher rpm and is pinpointed in the valve train,
perform the Repair Procedure.
NOTE:
MAKE SURE THE TICKING NOISE ORIGINATES IN THE VALVE TRAIN. USE A STETHOSCOPE OR OTHER LISTENING DEVICE TO
PINPOINT THE NOISE SOURCE.
