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 ...
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 3S-FE engine is fitted with a cast iron crankshaft, whereas the 3S-GE/GELU engines have forged crankshafts. [11] The 3S-FSE was a direct injection engine with Toyota D4 system. A cam driven high pressure fuel pump is at the #4 end of the head. This engine was only released in Japan, and installed in the Camry (Windom).
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 ...
[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.
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 ...
A timing belt is used to drive the valvetrain. Early production 2.0 L engines used a hydraulic tensioner to tension the timing belt. 2000 and 2001 engines used a mechanical spring-loaded tensioner that tended to wear out prematurely, causing serious valve and piston damage upon belt failure due to the interference design of the engine. 2002 and ...
The 2AZ-FE engine in the 2007-2009 Camry and 2006-2009 Rav4 may burn excessive oil and is involved in this lawsuit. [1] Other engines are also affected. [2] If this Toyota engine is burning more than 1 US quart (946 ml) of oil in 1,200 miles (1,931 km), has less than 150,000 miles (241,402 km), is less than 10 years old, and is located in the U.S., Toyota service will perform a free oil ...
