Engine Overview and Common Failures

The weight of the VQ23DE engine according to the catalog is 180 kg. The engine number VQ23DE is located at the junction of the block and the gearbox. The main problem with these engines is the entry of catalyst crumbs into the combustion chamber. If your oil consumption exceeds 1 liter per 1000 km, check the cylinders for scoring. There are many complaints about fluctuating idle speed due to idle air control valve contamination. Monitor the engine's temperature regime, as overheating quickly leads to cylinder head warping. Closer to 200,000 km mileage, the timing chain usually stretches and starts to rattle. Leaks from the camshaft position sensors or from under the valve cover are also encountered.
