Disadvantages of the VQ25DD engine
- Due to poor-quality fuel in the engine, nozzles and a high-pressure fuel pump often fail;
- Bad gasoline destroys the catalyst, and its crumbs are sucked into the combustion chamber;
- Scuffs form on the cylinder wall, which provokes a progressive oil burn;
- Even short-term overheating causes warping of the mating surface of the cylinder head;
- On a run of 200 thousand km, you will most likely have to replace the entire set of timing chains.
