The 1.8-liter 8-valve Peugeot XU7JP or LFZ engine was produced from 1992 to 2002 in France and then went to Iran, where it is still placed under the hood of local Samands. There are two different modifications of this motor: the main JP for 90 hp and XU7JB for 100 hp.
Engines of the XU family: XU5JP, XU7JB, XU7JP, XU7JP4, XU10J2, XU10J4R.

Disadvantages of the XU7JP engine
- A signature feature of the XU series motors is unstable operation in cold weather;
- Condensate often freezes in the crankcase ventilation tube and drives oil through the dipstick;
- Engine RPM fluctuates due to idle speed control stepper motor failures;
- Poor-quality gasoline quickly disables spark plugs, and then ignition coils;
- The timing belt often cracks before the prescribed 120,000 km, change it more often;
- There are no hydraulic lifters, so valve clearances have to be adjusted manually;
- The main places for oil leakage are the valve cover and the crankshaft oil seal.
