	Removing
1	Remove cylinder head covers	Air filter located at vehicle side.	AR01.20-P-5014B
		Air filter located on engine side.	AR01.20-P-5014BV
2	Check basic position of camshafts	If the basic position of the camshafts is not correct: ↓ Turn engine to 40° after ignition TDC at cylinder 1. The engine must not be turned back; otherwise the timing chain can get jammed.	AR05.10-P-6858V
