VANOS units, removing and installing (N12, N16, N18 engine) Engine timing is adjusted when pistons are locked in 90° position. This is an updated procedure that eliminates using top dead center (TDC) when setting camshaft and c rankshaft correlation. Special tools and procedures are required to remove and install VANOS units and to time camshafts.  — WARNING  —  To avoid personal injury, injury, be sure engine is cold before beginning the procedure. CAUTION —

• Disassembly, Disassembly, removal and assembly of camshafts or VANOS units without special tools poses the risk of damage: Valves Valves may be bent by contact with the piston crowns. • Throughout this procedure, unless otherwise specified, crankshaft and camshafts remain locked against rotation using MINI special tools.
