PCV Valve InspectionS7RS0B1206010
NOTE
Be sure to check that there is no obstruction 
in PCV valve or its hoses before checking 
IAC duty, for obstructed PCV valve or hose 
hampers its accurate adjustment.

2) Disconnect PCV valve from cylinder head cover and install plug to head cover hole.
3) Install air cleaner assembly temporarily.
4) Run engine at idle.
5) Place your finger over end of PCV valve (1) to check  for vacuum.
If there is no vacuum, ch eck for clogged valve. 
Replace as necessary. 6) After checking vacuum, stop engine and remove 
PCV valve (1).
Shake valve and listen for rattle of check needle 
inside the valve. If valve does not rattle, replace PCV 
valve.

For example of intake side:
When thickness of removed shim is 2.40 mm (0.094 
in.), and measured valve clearance is 0.45 mm 
(0.018 in.).
A = 2.40 mm (0.094 in.) + 0.45 mm (0.018 in.) – 0.20 
mm (0.008 in.) = 2.65 mm (0.104 in.) 
Calculated thickness of new shim = 2.65 mm (0.104 
in.)
