This subsection describes the types of repair of 4-cylinder engines 2.4 l and 2.7 l without dismantling from the vehicle. Twin-shaft engines with overhead valves. Camshaft drive - from the chain. Each cylinder has 2 intake and exhaust valves. The left camshaft (in the direction of the car) controls the intake valves, and the right camshaft controls the exhaust valves. The 2.7L engines are equipped with a balance shaft driven by a separate chain.
