The chain tensioner, also known as the phase regulator, causes the most problems. Also, make sure to monitor the condition of the timing belt, as valve damage can occur if it breaks. The crankcase ventilation often gets clogged, and the oil separator gasket hardens in freezing temperatures. The cause of engine power loss is usually due to throttle or intake valve contamination. The fan viscous coupling, water pump, and airflow meter have a relatively low lifespan here.
