Examination
If the camshaft or valve related components are removed, installed or replaced, or if abnormal engine operation is observed over time due to changes in valve clearances (failures occur during start-up, at idle speed or knocking occurs) please check as follows:
1. Warm up the engine. Then turn it off.
2. Remove the following components:
- protective cover from the front right wing;
- valve cover. See above section "Valve cover".
3. Turn the crankshaft pulley clockwise.
4. Make sure that the working projections of the camshafts of the intake and exhaust valves of cylinder No.1 are facing outward (the piston of cylinder No.1 is at TDC in the compression stroke).
Otherwise, turn the crankshaft pulley; it is still permissible to perform step 6 first (when the piston of cylinder No.4 is at TDC in the compression stroke).
5. Using the figure as a guide, measure the valve clearances using a feeler gauge at the locations marked with an "x" as indicated in the table below (in the figure the places are marked with black arrows).
Piston of cylinder #1 at TDC in compression stroke
| Cylinder | №1 | №2 | №3 | №4 | |
| Piston of cylinder No.1 at TDC in compression stroke | Inlet | X | X | ||
| Release | X | X | |||
Standard valve clearances:
Unit of measurement - mm
| Hot engine | Cold engine* | |
| Inlet | 0,314-0,426 | 0,29-0,37 |
| Release | 0,338-0,462 | 0,32-0,40 |
*Approx 20°C (reference data)
If the check was performed on a cold engine, make sure that the clearance values on a warm engine are still within the specified range.
6. Rotate the crankshaft pulley 360° clockwise (if you look from the front of the engine) and set the piston of cylinder No.4 to TDC in the compression stroke.
7. Using the figure as a guide, measure the valve clearances using a feeler gauge at the locations marked with an "x" as indicated in the table below (in the picture the places are marked with black arrows).
