How to check the valve tip clearances

1000 series » How to check the valve tip clearances

These are checked between the top of the valve stem and the rocker lever (A), with the engine hot or cold. The correct clearance for inlet valves is 0,20 mm (0.008 in) and 0,45 mm (0.018 in) for exhaust valves. The valve positions are shown at (B).

The sequence of valves from number 1 cylinder is shown in the table below.

Note: Number 1 cylinder is at the front of the engine.

Four cylinder engines

  1. Rotate the crankshaft in the normal direction of rotation until the inlet valve (B8) of number 4 cylinder has just opened and the exhaust valve (B7) of the same cylinder has not closed completely. Check the clearances of the valves (B1 and B2) of number 1 cylinder and adjust them, if necessary.
  2. Set the valves (B3 and B4) of number 2 cylinder as indicated above for number 4 cylinder. Then check / adjust the clearances of the valves (B5 and B6) of number 3 cylinder.
  3. Set the valves (B1 and B2) of number 1 cylinder. Then check / adjust the clearances of the valves (B7 and B8) of number 4 cylinder.
  4. Set the valves (B5 and B6) of number 3 cylinder. Then check / adjust the clearances of the valves (B3 and B4) of number 2 cylinder.

Six cylinder engines

  1. Rotate the crankshaft in the normal direction of rotation until the inlet valve (A12) of number 6 cylinder has just opened and the exhaust valve (A11) of the same cylinder has not closed completely. Check the clearances of the valves (A1 and A2) of number 1 cylinder and adjust them, if necessary.
  2. Set the valves (A4 and A3) of number 2 cylinder as indicated above for number 6 cylinder. Then check / adjust the clearances of the valves (A9 and A10) of number 5 cylinder.
  3. Set the valves (A8 and A7) of number 4 cylinder. Then check / adjust the clearances of the valves (A5 and A6) of number 3 cylinder.
  4. Set the valves (A1 and A2) of number 1 cylinder. Then check / adjust the clearances of the valves (A11 and A12) of number 6 cylinder.
  5. Set the valves (A9 and A10) of number 5 cylinder. Then check / adjust the clearances of the valves (A3 and A4) of number 2 cylinder.
  6. Set the valves (A5 and A6) of number 3 cylinder. Then check / adjust the clearances of the valves (A7 and A8) of number 4 cylinder.
