Checking
Notice
The noise which continues short time during short travel
(frequent starting of the engine) or engine starting after a
long time storage is normal operating conditions. So, it does
not need to be repaired. Determine the malfunctions in valve
clearance compensation device with noise through following
tests. If defective, replace as respectively.
1. Run the engine at more than 3000rpm for approx. 4 minutes.
2. Stop the engine. After 5minutes, check the engine oil level
and adjust if necessary.
3. Remove the cylinder head cover.
4. Check the valve tappets at TDC position of each cylinders.
5. Using a drift, lightly press the valve tappet and measure
clearance between the cam and valve tappet.
Notice
If the clearance exceeds 0.4mm, replace the valve tappet.
6. If a valve tappet moves down too far in comparison to the
others, replace the valve tappet.
7. Rotate the engine and check the remaining valve tappets.
Notice
lUnnecessary rotation of the engine will damage the valve
tappets.
