Engine Overview and Common Failures

The weight of the CTSA engine assembly is 183 kg. The CTSA engine number is located at the junction of the block and the oil pan. The timing chain in the engine doesn't last long, sometimes it stretches up to 100,000 km. The valves here quickly get clogged with carbon deposits due to the presence of a direct injection system. The evaporative emissions canister valve occasionally fails and it's better to replace the entire unit. The crankcase ventilation requires regular cleaning, otherwise it may clog and cause leaks. Also, lubricant often seeps from under the valve cover and the timing belt side cover.
