Slapping or Ticking Noise at Idle on 2013-14 Honda 2.4L Engines
Honda has determined that a possible cause of this problem is debris that is restricting oil flow to the cam chain auto-tensioners. To cure this problem, Honda suggests replacement of the cam cha auto-tensioner and install a cam chain auto-tensioner filter.
The procedure is listed below to properly remedy this slapping or ticking noise.
- Remove the chain case cover
- Clean the chain case cover as show in Figure 1.
- Rotate the crankshaft counterclockwise, Figure 2, until the cam chain auto-tensioner is compressed.
- Remove the cam chain auto-tensioner. Note: Use a 1.2mm diameter pin, a large paper clip or similar item to hold the auto-tensioner arm in a locked position for removal as shown in Figure 3.
- Remove the oil filter
- Place a shop towel over the place on the engine block where th cam chain auto-tensioner mounts.
- Using shop air, place the air nozzle into the oil filter mounting adapter as shown in Figure 4.
- Blow compressed air for 5 second through the oil passage to clear any debris before installing the cam chain auto-tensioner as shown in Figure 5.
- Install a new oil filter
- Install the cam chain auto-tensioner filter onto the new chain auto-tensioner as shown in Figure 6.
- Install the new cam chain auto-tensioner with filter and torque the bolts to 12 Nm (9 ft/lbs)
- Apply a 2.5mm diameter bead of Hondabond 4 along the case cover as shown in Figure 7.
- Install the chain case cover and torque bolts to 12 Nm (9 ft/lbs)
