Mitsubishi Triton 1996 FAQs

Check out real-world situations relating to the Mitsubishi Triton here, particularly what our experts have to say about them.

• Knocking sound coming from my 2014 Mitsubishi Triton manual

  From memory, this model Triton featured a dual-mass flywheel. These were fitted to smooth out the engine and make gear changes quieter and smoother. But when they fail, they can produce the sort of symptoms you’re hearing.

  Instead of a one piece, solid flywheel, the dual-mass unit is made in two parts with flexible couplings between them. These couplings absorb some of the shock of gear-shifts and engine vibrations, but when they’re worn out, the whole assembly becomes `loose’ and starts producing clunks and bangs. Replacing the flywheel is the only fix, but make sure you replace the clutch assembly at the same time. Some companies also offer a single-piece flywheel conversion for this vehicle to prevent the problem occurring again.

• My 2018 Mitsubishi Triton engine has a blow-by from the oil filler cap

  Blow-by is a normal part of engine operation, particularly turbocharged engines where the combustion chamber pressures can be extremely high, forcing gasses past the piston rings and into the crankcase. Excess blow-by, however, suggests that there’s perhaps an overboost problem, wear in the engine or that the ventilation system designed into the emissions controls of the engine is not working properly.

  The crankcase ventilation valve would be a good place to start checking as these can become very dirty and even clogged over time in a diesel engine, and a compression test of the engine might tell you more as well. The first thing to do is find another vehicle of the exact same make and model and see if it, too, has a similar level of blow-by in evidence. From there, you can decide which way to go, but either way, a good diesel mechanic should be able to identify the problem accurately.

• Why does the fuel pump of my 2009 Mitsubishi Triton buzz?

  What you’re probably hearing is the pump switching on to prime the engine’s fuel system so that it starts easily and promptly. Even though the engine isn’t running, when you switch the ignition on, systems like the fuel pump all come to life to get things ready to be started and driven. When the pump has generated enough fuel pressure and volume to start the engine, it can then switch off and only switch on again once the engine is running and a constant supply of fuel is required. This could be why it only runs for a few seconds when you first turn the ignition on.

  This is pretty normal, but what isn’t is if the pump starts to make a new noise or the tone of its buzzing changes. At that point, what you might be hearing is wear or damage inside the pump.
