Maintenance procedures

Valve clearance check and adjustment

Non-VVT-i models -every 54 000 miles or 6 years
VVT-i models - every 60 000 miles or 6 years
Non-VVT-i engines

Note: The following procedure requires the use of a special tool (Toyota No 09248-55020) which compresses the cam follower a little to enable the removal of the adjustment shim. Without the tool, it will be necessary to remove the camshaft(s) as described in Chapter 2A.

1. Remove the cylinder head cover as described in Chapter 2A.
2. Remove the spark plugs (see Section 20).
3. Refer to Chapter 2A and position the number 1 piston at TDC on the compression stroke.
4. Measure the clearances of the indicated valves with feeler gauges (see illustration). Record the measurements for those which are out of specification. They will be used later to determine the required shims.
5. Turn the crankshaft one complete revolution and realign the crankshaft timing marks. Measure the remaining valves (see illustration).

• Keep pressure on the cam follower with the smaller tool and remove the shim with a small screwdriver

• When the No 1 piston is at TDC on the compression stroke, the valve clearance for the No 1 and No 3 cylinder exhaust valves and the No 1 and No 2 intake valves can be measured

• When the No 4 piston is at TDC on the compression stroke, the valve clearances for the No 2 and No 4 exhaust valves and the No 3 and No 4 intake valves can be checked
