○ Ensure conformity with electronics, the injection and the exhaust system

○ The engine makes a knocking noise when accelerating

○ The engine consumes oil

○ The timing belt is broken 

○ There is a loss of power and less compression

○ Cooling radiator

○ Turbo, if fitted

○ Timing kit

○ Coolant pump

○ Accessories kit (tensioner rollers + alternator belt)
