Engine BMW N62B36

The basis for the development of the N62B36 was the older brother N62B44, in the cylinder block of which a crankshaft with a stroke of 81.2 mm (was 82.7 mm) was installed, the cylinder diameter was reduced to 84 mm (was 92 mm) and the connecting rods were replaced.

The cylinder head is similar to the 4.4-liter counterpart, but with a reduced diameter of the intake valves to 32 mm, the exhaust valves are the same, 29 mm. Characteristics of the standard N62B36 camshafts: phase 282/254, lift 0.3-9.85/9.7. Relative to the previous version of the small V8, the N62B36 introduced the Valvetronic intake valve lift system and the Dual-VANOS / Bi-VANOS intake and exhaust valve timing system. Bosch DME ME 9.2 engine management system.

Other modifications of N62: N62B40, N62B44, N62B48.

Disadvantages of the N62B36 engine

  • The main problems of the motor are associated with malfunctions of the Valvetronic and VANOS systems;
  • In second place is the growing oil consumption due to wear of valve stem seals;
  • Floating RPM is usually caused by ignition coils or flowmeters;
  • Very often the sealing gasket of the generator housing and the crankshaft oil seal are leaking;
  • On a long run, crumbs from a collapsing catalyst are sucked into the cylinders.
