	Check and adjust valve play with cold engine. Wait at least 30 minutes after engine shutoff, even in the case of having had it running for a brief interval, to ensure a uniform temperature
1	Remove the head cover	For free breath engines.	AR01.20-B-5014C
		For engines with regulating valve (PCV).	AR01.20-B-5014D
		For CNG fired engines, 376.922.	AR01.20-B-5014E
		For CNG fired engines, 376.919.	AR01.20-B-5014J
2	Determine the method to proceed with the valve adjustment	 Method 1: following the injection order.	AH05.30-B-1000-01C
		 Method 2: in two camshaft positions.	AH05.30-B-1000-01C
3	Turn the engine to the crankshaft positions determined by the adjustment method chosen
4	Check the valve clearance (arrow) and adjust if necessary.	The value to be confirmed is valid only in the cases of valve play verification. To carry out play adjustment, consider “adjustment value”.	AP05.30-B-0560-01E
