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 1.5 L 1A was produced between 1978 and 1980. [6] All variants were belt-driven 8-valve counter-flow SOHC engines with a single, twin-barrel downdraft carburetor.It used Toyota's Turbulence Generating Pot (TGP) lean combustion system to meet Japanese emissions standards at the time with only an oxidation (2-way) catalyst.

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.
Some engines don’t share the same displacement as with the one found in the engine code. For example, the displacement of the V35A-FTS is closer to 3.4 L despite being marketed as a 3.5 L engine. Moreover, there are a few engines that use the naming scheme of the Dynamic Force family of engines but are not actually part of them, such as the ...
1993–97 3.5 L engines are a non-interference design, in which the valves will not collide with the pistons in the event of a timing belt failure. The 1998–2001 3.2 L, the 1998–2010 3.5 L, and the 2007–2011 4.0 L engines are interference designs.
Another cause for timing belt failure is improperly adjusting the timing belt on engines with a manual tensioner (1989 to very early 1990 models only) or improperly adjusting the balance shaft belt. Because this is an interference engine, damage will occur if the timing belt fails. Another common occurrence is that the balance shaft's oil seals ...
The Toyota E engine family is a straight-four piston engine series, and uses timing belts rather than chains. The E engines were the first multi-valve engines from Toyota designed with economy, practicality and everyday use in mind (rather than performance). Like many other Toyota engines from the era, the E engine series features a cast iron ...
[11]: 94–95 [12]: 250 If the timing belt is not replaced in time and fails and the engine is an interference engine, major engine damage is possible. The first known automotive application of timing belts to drive overhead camshafts was the 1953 Devin-Panhard racing specials built for the SCCA H-modified racing series in the United States.
