Disadvantages, breakdowns and problems of the internal combustion engine 406PN
With reliability, this engine is doing well, but fuel consumption will not please you
The choice of spare parts is small, since the unit was offered only in the USA and Australia
The main problems here are delivered by an unusual and not very reliable timing chain.
On high mileage, it is often necessary to repair both cylinder heads with the replacement of all valves
Also, the EGR tube regularly cracks here and the crankshaft rear oil seal sweats.
