Checking the camshaft
1. Check the camshaft journals for wear. If the journals are significantly worn, replace the camshaft.
Engines 2.0 p/ 2.4 l:
- The diameter of the camshaft bearing journal: 26 mm.
2.7L Engine:
- Camshaft journal diameter:
- Nominal value: 25.964-25.980 mm
- Maximum permissible value: 25.914 mm
2. Check the protruding part of the camshaft lobes for damage. If the camshaft lobes are damaged or their wear exceeds the permissible value, replace the camshaft.
Camshaft cam height:
- Nominal value:
- 2.0L/2.4L Engines:
- Intake: 35.493 mm
- Exhaust: 35.317 mm
- 2.7L Engine: 43.95 - 44.15 mm
- Maximum permissible value:
- Engines 2.0L/2.4L:
- Intake: 34.993 mm
- Exhaust: 34.817 mm
- 2.7L Engine: 43.450mm

Engine 2.7 l. |
3. Check the surface of the back of the camshaft lobes for damage or significant wear, and replace the shaft if necessary.
4. Check the condition of the camshaft bed (absence of damage) and the oil clearance in the camshaft bearings. If the wear of the camshaft bed exceeds the permissible value, replace the cylinder head assembly or the camshaft bearing caps.
Camshaft Bearing Clearance:
- Nominal value:
- 2.0L/2.4L engines: 0.040-0.076 mm
- 2.7L Engine: 0.020-0.061 mm
- Maximum permissible value (2.7L engine): 0.1 mm
5. Measure the axial clearance of the camshaft and, if the measured value exceeds the upper limit of the nominal value range, replace the camshaft. If necessary, replace the bearing caps and cylinder head.
Nominal value:
- 2.0L/2.4L Engine: 0.10-0.20mm
- 2.7L Engine: 0.10-0.15mm
Checking the camshaft seal
1. Check the seal lip for wear. If the lip is worn, replace the seal.
2. Check the condition of the camshaft surface that contacts the seal lip. If the surface is worn, replace the camshaft.
