Examination
Camshafts
1. Check the camshaft for uneven wear, cracks or damage.
2. At two points, measure the height of each camshaft lobe.
Nominal height of intake camshaft cams:
- engines 1.8 and 2.0 l, except CVVT: 44.820 mm;
- 1.6 L engines: 43.4484 mm.
Nominal exhaust camshaft height:
- engines 1.8 and 2.0 l, except CVVT: 44.720 mm;
- 1.6L engines: 43.8489 mm.
Minimum allowable height of the intake camshaft cams:
- engines 1.8 and 2.0 l, except CVVT: 44.720 mm;
- 1.6 L engines: 42.9484 mm.
Minimum allowable exhaust camshaft height:
- engines 1.8 and 2.0 l, except CVVT: 44.620 mm;
- 1.6 L engines: 43.3489 mm.
3. Check the cam surfaces for uneven wear and damage.
4. Check each bearing for damage. If the bearing surface is excessively damaged, replace the cylinder head or camshaft bearing cap.
Camshaft end play:
- engines 1.8 and 2.0 l: 0.1–0.2 mm;
- 1.6L engines: 0.1–0.15 mm.
Camshaft front O-ring
1. Check the sealing ring lips for wear. If the lip is worn or damaged, replace the O-ring.
2. Check the surface of the camshaft in contact with the O-ring. If this surface is evenly worn, replace the camshaft.
