The 4M40 engine is a diesel, in-line, 4-cylinder. Overhead camshaft. The 4M40 cylinder block is made of cast iron, the block head is made of aluminum alloy. It was offered in atmospheric and turbo versions, with a mechanical and electronic injection pump.
Mitsubishi 4M40 is better known as the engine for Pajero 2. It was first installed on this SUV in 1993. The diesel 4M40 was introduced to replace the old 4D56, which was still produced after that for some time. The engine has established itself as powerful and reliable, but time does not stand still – a new 4M41 with a displacement of 3.2 liters was already installed on the Pajero 3. This engine is the result of the 4M40’s identified and corrected weaknesses.
4M4 family: 4M40, 4M41.

Disadvantages of the Mitsubishi 4M40 engine
- mechanical injection pump Bosch VE is quite capricious and regularly flows through the shaft seal;
- in the electronic injection pump, the control lever position sensor or TPS is constantly buggy;
- EGR valve and intake manifold flaps quickly become overgrown with soot and get stuck;
- viscous fan clutch and heating control unit may fail up to 100,000 km;
- at high mileage, the cylinder head often cracks, the timing chain is pulled out, the turbine is rented out.
