Set No.1 Cylinder To Tdc/Compression; Inspect Valve Clearance - Toyota 22R-E Service Manual

ENGINE – ENGINE MECHANICAL

6. SET NO.1 CYLINDER TO TDC/COMPRESSION

(a) Turn the crankshaft pulley and align its groove with
timing mark "0" of the No.1 timing belt cover.
(b) Check that the valve lifters on the No.1 cylinder are
loose and valve lifters on the No.4 are tight.
If not, turn the crankshaft one revolution (360S) and
align the mark as above.

7. INSPECT VALVE CLEARANCE

(a) Check the clearance of the 1N (No.6) and EX (No.2)
valves.
Using a feeler gauge, measure the clearance be–
tween the valve lifter and camshaft.
Record the out– of –specification valve clear–
ance measurements. They will be used later to
determine the required replacement adjusting
shim.
Valve clearance (Cold):
Intake
0.18 – 0.28 mm (0.007 – 0.011 in.)
Exhaust
0.22 – 0.32 mm (0.009 – 0.013 in.)
(b) Turn the crankshaft 1/3 revolution (120S), check the
clearance of the IN (No. 1) and EX (No. 3) valves.
Measure the valve clearance.
(See procedure in step (a))
(c) Turn the crankshaft 1/3 revolution (120S), check the
clearance of the IN (No. 2) and EX (No. 4) valves.
Measure the valve clearance.
