BMW 11127588249 Cylinder Head

To remove the N55 engine cylinder head, first remove the engine, as special tools and procedures are necessary for the removal and installation of camshaft adjustment units and for timing camshafts. It is important to read the entire procedure before beginning repairs. Disassembly, removal, and assembly of camshafts, camshaft adjustment units, or the cylinder head without BMW special tools can lead to damage or breakage, such as bent valves from contact with piston crowns or a camshaft snapping if bent by valve springs. If a cylinder head requires significant reconditioning work after removal, a remanufactured cylinder head is available from an authorized BMW dealer.
