The 2.2 liter motor can be either an interference or non-interference motor, depending on the specific engine design and model year. Some variations of the 2.2 liter engine have interference valves, which means that if the timing belt or chain fails, the pistons can collide with the open valves and cause severe engine damage. Other versions of the 2.2 liter engine have non-interference valves, which means that the pistons and valves are designed to avoid collision even in the event of a timing belt or chain failure.
To determine whether your 2.2 liter engine is an interference or non-interference motor, it is best to refer to the owner's manual or specific vehicle repair literature for your particular make and model.
