Disadvantages of the N63B44 engine

This engine has so many problems it would take forever to list them all;

First of all, this is an oil burner due to the wear of the valve stem seals and the occurrence of rings;

The threads in the soft aluminum cylinder block are weak and the head can rise;

Ordinary candles here very quickly fail and misfires begin;

After a long stay, you can get a water hammer due to the overflow of piezo injectors;

The oil supply pipes to the turbine gradually coke, which reduces their life;

The timing mechanism with dual-VANOS and Valvetronic systems has low reliability.
