The older brother N62B44 served as the model for the N62B36, which was developed by replacing the connecting rods, reducing the cylinder diameter to 84 mm (from 92 mm), and installing a crankshaft with a stroke of 81.2 mm (from 82.7 mm) in the cylinder block.
The cylinder head is comparable to its 4.4-liter equivalent, but the intake and exhaust valves have smaller diameters—32 mm and 29 mm, respectively. Standard N62B36 camshafts have phase 282/254 and lift 0.3-9.85/9.7. The N62B36 introduced the Dual-VANOS/Bi-VANOS intake and exhaust valve timing system and the Valvetronic intake valve lift system in contrast to the previous iteration of the small V8. Engine management system Bosch DME ME 9.2.
N62B40, N62B44, and N62B48 are additional N62 modifications.

Disadvantages of the N62B36 engine
The primary issues with the motor are related to Valvetronic and VANOS system malfunctions; increasing oil consumption as a result of valve stem seal wear comes in second;
Flowmeters or ignition coils are typically the cause of floating RPM.
The crankshaft oil seal and the generator housing sealing gasket frequently leak; over time, crumbs from a collapsing catalyst are drawn into the cylinders.
