NOTICE: Only rotate the crankshaft clockwise.
Rotate the crankshaft until the corresponding piston is at TDC and then measure the valve clearance(s).
Use the General Equipment: Feeler Gauge

Measure and note the valve clearance values.

Compare the measured valve clearance(s) with the specifications.
Refer to: Specifications (303-01C Engine - 1.4L Duratec-16V Flex Fuel (71kW/96PS) – Sigma, Liquefied Petroleum Gas (LPG), Specifications).

Adjustment

NOTE: The following steps are only necessary if adjustment is required.

Remove the following items:
- Refer to: Camshafts (303-01C Engine - 1.4L Duratec-16V Flex Fuel (71kW/96PS) – Sigma, Liquefied Petroleum Gas (LPG), Removal and Installation).

- Remove the valve tappet and read the thickness from the underside.
- The number on the valve tappet indicates the thickness of the bottom of the tappet. However, the number only indicates the digits after the decimal point (example: 725 = 2.725).

Calculate the valve tappet thickness required (thickness of the currently installed tappet + the measured valve clearance - the required valve clearance).

Install the correct valve tappet.

NOTE: The component must be installed within 5 minutes of applying the sealant.
Complete this step within: 5min

- Turn the crankshaft back by 45° (counter to the normal direction of rotation).
- Turn the camshafts to measure the valve clearance.
- Repeat the procedure as necessary until all valve clearances are within the specified tolerance.
- Turn the crankshaft until it stops against the special tool.
