Powertrain
Below are the valve lash specifications.
Measure Valve Clearance on CVVT engine:
ECT: 68° F
Specification:
Intake: 0.0079"
Exhaust: 0.0110"
Limit:
Intake: 0.0067-0.0091"
Exhaust: 0.0098-0.0122"
1. Using the adjusting shim selection chart (Exhaust),
determine the new shim needed so that the valve
clearance comes within the specified value, if the:
Measured valve clearance of: 0.0280"
Thickness of removed shim: 0.0882"
New shim thickness: _____________________
(See shim chart on the next page)
2. Using your 2.0L Valve Inspection and Adjustment
sheet, review the key steps to remove a shim.
Make any notes below as you perform the
procedures:
