Disadvantages of the Mitsubishi 4M41 engine
- In the first versions of the engine without Common Rail, the high pressure fuel pump often failed and the pistons burned out;
- The updated modification has become much more reliable and practically does not bother;
- A crankshaft pulley with a rubber clutch can fall apart even at low mileage;
- The timing chain serves approximately 200 – 250 thousand km, and then it stretches and rings loudly;
- About once every 50,000 km you have to clean the EGR and tighten the alternator belt.

I have a 2014 Pajero with 4m41, what’s the best fuel tonuse as where I live we still have 2 diesel fuels avaliable at the pump, ulsd and plain old school diesel
All the 4M41 versions with a distribution pump (equipping the 3rd generation Pajero) are generating 373Nm or more depending on the destination country. Evenmore, for this same version of 4M41 with a distribution pump there are different level of engine outputs: 160HP, 165HP and 175HP.
Fof example the 4M41 with a distribution pump installed on the 3rd Gen Pajero Japenese specs (JDM) is producing 382Nm and 175HP.
I’ve driven over 470.000km with my timing chain, no noise and no stretch.
The 2 things you need to do is changing oil as required, and change the timing chain guide between the camshafts around 200.000-250.000km.
The chain guide you change at the same time you do the valve clearence check, it’s 2 bolts from the top and takes less than 1min to change.
