The 1.8-liter, 8-valve Peugeot XU7JP, also known as the LFZ engine, was manufactured in France between 1992 and 2002 before being shipped to Iran, where local Samands continue to use it under the hood. This motor comes in two different versions: the XU7JB for 100 horsepower and the main JP for 90 horsepower.
The XU family of engines includes the XU5JP, XU7JB, XU7JP, XU7JP4, XU10J2, and XU10J4R.

Disadvantages of the XU7JP engine
Unstable operation in cold weather is a distinguishing characteristic of the XU series motors;
Oil is frequently forced through the dipstick by condensate that freezes in the crankcase ventilation tube;
Idle speed control stepper motor failures cause engine RPM fluctuations;
Spark plugs and ignition coils are rapidly rendered inoperable by subpar gasoline;
Replace the timing belt more frequently because it frequently cracks before the recommended 120,000 kilometers;
The valve cover and the crankshaft oil seal are the primary locations for oil leaks because there are no hydraulic lifters, so valve clearances must be manually adjusted.
