A pair of poppet valves bent by collision with a piston after timing belt failure. The engine was running at 4500 RPM. In interference engine designs, replacing a timing belt in regular intervals (manufacturers recommend intervals ranging from 60,000 to 104,000 miles) or repairing chain issues as soon as they are discovered is essential, as incorrect timing may result in the pistons and valves ...
The 1966 Pontiac OHC Six engine was the first US mass-produced vehicle to use a timing belt, [21] [22] while the 1966 Fiat Twin Cam engine was the first mass-produced engine to use a timing belt with twin camshafts. Carmakers began to adopt timing belts in the 1970s and compared to timing chains are less expensive, smaller, lighter, quieter ...
One critical maintenance issue specific to the Yugo 55 and 65 (the 45 was a 903 cc pushrod engine, with a timing chain) [39] was the need for regular replacement of the interference engine's timing belt — every 40,000 miles (64,000 km). [38] In a non-interference engine, timing belt failure does not cause further damage to the engine.
The 2RZ-FE is an interference engine with a timing chain. [ 2 ] [ 3 ] A 2.2 L (2,185 cc) version called the 4RB3 is also manufactured in China which has a bore and stroke of 91 mm × 84 mm (3.58 in × 3.31 in), while sharing the 2RZ's 102.5 mm (4.04 in) bore spacing.
The 3.3 has a timing chain, and is an interference engine meaning that the valves will collide with the pistons in the event of a timing chain failure. Vehicles using the 3.3 include: 1990–1993 Dodge Dynasty, Chrysler New Yorker, Chrysler Imperial, (replaced the 3.0 L Mitsubishi 6G72 engine) 1990–2010 Chrysler minivans

The Prince engine is a family of inline-four 16-valve all-aluminium petrol engines with variable valve lift and variable valve timing developed by PSA Peugeot Citroën and BMW. It replaced a part of the TU line (the other part was later replaced by the EB engine) and both the ES and EW lines. Engines: EP3 — 1.4 L (1,397 cc) Euro 4 70-72 kW
The DOHC and SOHC 16-valve 4G64 are interference engines, while the SOHC 8-valve 4G64 is a non interference engine. From March 1996 an LPG version with 115 hp (86 kW; 117 PS) at 5,000 rpm was available in the Mitsubishi Canter .
