  1. Check the camshaft journals for wear. If the journals are badly worn, replace the camshaft.

  1. Check the cam lobes for damage. If the lobe is damaged or worn excessively, replace the camshaft.

    Cam height (Intake [1.8L]) 44.449 mm ( 1.7499 in )
    Cam height (Intake [2.0L]) 44.049 mm ( 1.7342 in )
    Exhaust 45.049 mm ( 1.7736 in )
    Cam height (Intake [1.8L]) 44.349 mm ( 1.7460 in )
    Cam height (Intake [2.0L]) 43.949 mm ( 1.7302 in )
    Cam height (Intake) 44.949 mm ( 1.7696 in )
  1. Check the cam surface for abnormal wear or damage, and replace if necessary.

  1. Check each bearing for damage. If the bearing surface is excessively damaged, replace the cylinder head assembly or camshaft bearing cap, as necessary.

    Camshaft end play 0.1-0.2 mm (0.004-0.008 in.)
Oil Seal front Camshaft
  1. Check the lips for wear. If lip threads are worn, replace.

  1. Check the oil seal lip contacting surface of camshaft. If it is worn is stages, replace the camshaft.

HLA (Hydraulic Lash Adjuster)

With the HLA filled with engine oil, hold A and press B by hand, If B moves, Replace the HLA.

For other specific troubleshooting regarding HLA, refer to the table below.

Possible cause
Temporary noise on starting a cold engine
This noise will disappear after the oil in the engine has reached normal pressure.
Continuous noise when engine is started after longer than 48 hours parking.
Oil drain out of the high pressure chamber on HLA, allowing air to get in.
Noise will disappear within 15 minutes when engine run at 2000-3000 rpm. If not disappear, refer to the step 7 below
Do not run engine all a speed higher than 3000 rpm as this may damage HLA.
Continuous noise when engine is first started after rebuilding cylinder head.
Insufficient oil in cylinder head oil gallery.

Continuous noise when engine is after excessive cranking the engine by starter motor or band.
Oil drain out of the highpressure chamber in HLA, allowing air to get in. Insufficient oil in HLA.

Continuous noise after changing HLA.

Continuous noise during idle after high speed running.
Engine oil level too high or too low.
Check oil level. Drain or add oil as necessary.

Excessive amount of air in the oil at high engine speed.
Check oil supply system

Deteriorated oil
Check oil quality. If deteriorated, replace with specified type and amount of oil.
Noise continues more than 15 minutes.
Low oil pressure
Check oil pressure and oil supply system of each part of engine.

Faulty HLA.
Remove the cylinder head cover and press down HLA by hand. If it moves, replace HLA.
Be careful of hot HLA.
Chain guide
  1. Check the chain guide for bended, cracks or damage.

    Replace if necessary.

  1. Check the rubber part of chain guide for abnormal wear.

    Replace if necessary.

Timing chain

Check the bushing and plate of timing chain for wear. Replace if it is worn severely.

  1. Install the HLA.

  1. Align the camshaft timing chain with intake timing chain sprocket and exhaust timing chain sprocket as shown.

  1. Install the camshaft after lubricating the journal of camshaft with engine oil.

  1. Install the bearing caps. Check the markings on the caps for intake/exhaust identification symbol.

I: Intake camshaft

E: Exhaust camshaft

  1. Tighten the bearing caps to the specified torque in two or three steps as shown.

    Bearing cap bolt 12-14 Nm ( 120-140 kg·cm, 9-10 lb·ft )
  1. Using special tool, camshaft oil seal installer (09221-21000), press the camshaft oil seal. Be sure to apply engine oil to the external surface of the oil seal. Insert the oil seal along the camshaft front end and install by driving the installer with a hammer until the oil seal is fully seated.

  1. Install the camshaft sprocket to the specified torque.

    Camshaft sprocket bolt 80-100 Nm ( 800-1000 kg·cm, 60-74 lb·ft )
  1. Align the camshaft sprocket and crankshaft sprocket timing marks. The piston in the No.1 cylinder will then be at the being checking to see preceding correctly top dead center on the compression stroke.

  1. Install the cylinder head cover.

    Cylinder head cover bolts 8-10 Nm ( 80-100 kg·cm, 6-7 lb·ft )
  1. Install the spark plug cables, ignition coil assembly and cylinder head center cover.

  1. Install the timing belt and then tighten the timing belt tensioner pulley.

  1. Install the timing belt cover.

  1. Install the coolant pump pulley and crankshaft pulley.
