Engine Peugeot XU7JB

The 1.8-liter 8-valve Peugeot XU7JB or LFX engine was produced from 1995 to 2001 and was installed on many well-known models of the concern: Peugeot 406, Partner, Citroen Xsara and Xantia. This power unit, in fact, was only a slightly deformed version of the XU7JP motor.

Engines of the XU family: XU5JP, XU7JB, XU7JP, XU7JP4, XU10J2, XU10J4R.

In 1995, the concern released a version of the popular XU7JP engine derated to 90 hp. In addition to slightly reduced engine power and a slightly different degree of compression, there were no special differences: there was an injection injection, an aluminum block with so-called wet cast iron liners, an aluminum 8-valve cylinder head without hydraulic lifters, and a simple timing belt drive.

Disadvantages of the Peugeot XU7JB engine

  • This strong and resourceful motor is famous for regular electrical failures. More often than others, the following fail: a gasoline pump, a stepper motor in the idle speed controller, as well as throttle position and coolant temperature sensors.
  • The engine is equipped with a simple cable-actuated throttle, but there are enough complaints about it: its damper not only gets dirty pretty quickly, but also regularly freezes over in winter. Also, in cold weather, the crankcase ventilation pipes can freeze and the oil will be squeezed out through the dipstick.
  • Also, owners often have to deal with air leaks, lubricant leaks, adjust valve clearances and monitor the belt, as the valves bend when it breaks. Also, due to the air intake being too low, you can grab a water hammer.
