Engine Overview and Common Failures
The weight of the G16A engine assembly is 105 kg. The G16A engine number is located at the junction with the gearbox. Cracks in the block. The most well-known problem of such units are cracks in the cooling jacket. If you are losing coolant, do not attempt to repair the aluminum block, but look for a replacement. Exhaust manifold. The exhaust manifold often cracks here, but it can be welded. In 1994, a stronger version of the manifold was introduced, so if you need to replace it, it's best to choose that one. Ignition system. Like any engine with an outdated ignition system, it causes a lot of trouble. But the engine also has a known weak spot - during winter, the spark plugs tend to get flooded. Timing belt breakage. According to the regulations, the timing belt should be replaced every 90,000 km, but most owners use non-original belts with a shorter lifespan. Luckily, the valves don't get bent. Other shortcomings. Owners of cars with this engine constantly complain on the specialized forum about leaks, and especially often, lubricant seeps out from under the distributor or directly through its pressure sensor.
