Engine Overview and Common Failures
Oil consumptionThe most well-known problem is excessive oil consumption, which is caused by ring sticking. Owners fight against oil consumption by choosing the optimal lubricant and with some success. It is worth remembering that there is no oil level sensor, so it is necessary to regularly check the dipstick.
Uneven warming upDue to the design features of the exhaust system of this engine, exhaust gases constantly flow back into the cylinders, causing thermal imbalance. This leads to uneven engine operation, vibrations, and also reduces its lifespan. Since the exhaust manifold is integrated with the cylinder head, it is not possible to replace it with an alternative.
Oil leaksIf you have discovered fresh traces of lubrication in the timing belt housing, then most likely the seals of the camshafts are leaking. However, the operation to replace them is quite inexpensive.
Coolant leaksThe plastic water pump with two built-in thermostats often starts to leak at a mileage of 100,000 km. The problem is not the fact of leakage, but rather the high cost of the part.
Tapping of hydraulic liftersAs soon as the oil approaches the minimum mark, the hydraulic lifters start tapping under the hood. They are especially audible when the engine is cold and has not yet warmed up.
