Disadvantages of the Mitsubishi 4D65 engine
- Most problems for owners are caused by oil leaks from gaskets and seals;
- The timing belt is designed for 90,000 km, but it can break earlier and break the rocker;
- The balance shaft belt serves about 50,000 km and falls under the timing when it breaks;
- Often the engine pulleys burst, especially the one that sits on the crankshaft;
- On long runs, cracks often appear in the area of the prechambers of the head of the block.
