- His main problem is the cracking of the cylinder head from any overheating;
- Non-original oil quickly affects the operation of the turbine and hydraulic lifters;
- On runs over 300 thousand km, the prechambers can crack and fall out into the cylinders;
- Most of the spare parts for this engine are unreasonably expensive and not common.
