Mounting Tools

• To install and remove camshaft / hydraulic chain tensioner.
• To check and adjust camshaft timing correctly.
• The N42 and N46 1.8 & 2.0 twin camshaft petrol engines have the Vanos variable camshaft timing unit on the both inlet and exhaust camshaft.
• BMW Valvetronic system which varies the timing and the lift of the inlet valve.
• The Valvetronic layout incorporates a conventional inlet camshaft and
a secondary eccentric shaft, with intermediate lever and follower, activated by a stepper motor. The stepper motor changes the phase of the eccentric shaft, altering the action of the inlet valve.
• These are positioned in a camshaft carrier bracket in the cylinder head.
