Why My Mitsubishi Triton Blows White Smoke And Is Missing From 2000-3000 RPM

Brooke Hamilton • Jul 08, 2018

Mitsubishi Triton’s both the 4D56 and 4M41 engines, have a significantly higher EGR intake manifold build-up problem, more so than many other manufacturers. They present as almost like a fuel system issue, because the miss is so heavy and the white smoke so significant the car is virtually un-drivable.

The Problem

The reality is it’s actually caused by dirty and clogged intake manifolds, this then causes issues with the many boost solenoids, vacuum solenoids, and anything else that relies on air flow through the intake manifold.

The Diagnosis and Solution

So if you get a Mitsubishi Triton with this issue, the repair should be performed in the following steps:

  1. Completely remove the entire intake manifold
  2. Physically clean and remove all the buildup – Ultrasonic cleaning is great for this
  3. Put it back on, and make sure all the vacuum lines and everything else is performing correctly.

If you still having issues, go chasing from there, however in our experience the intake clean will be the solution.
