The engine is lubricated under pressure, produced by a gear pump, which one in the engine 1.2 it is housed in the crankcase and driven by the camshaft, and in engines 1,3 and 1,6 D is located on the front, in the axis of the crankshaft (made as a centrifugal pump).
The oil pressure should be within the range of all types of engines 1.5 kG/cm2 (0,15 Mpa), measured when heated (oil temperature 60 ° C, coolant 80 ° C) at idle.
Replace the oil pan gasket (engine 1,2)
■ Drain the engine oil.
■ Screw the oil drain plug back in with a new seal (tightening torque 45 Nm).
■ Remove the screws securing the engine support to the clutch housing from below,
■ Remove all bolts holding the oil pan.
■ Remove the oil pan and clean the contact surfaces.
Before screwing in the oil pan after replacing the gasket, apply sealant in the places indicated: on the edges of the rear bearing cap of the crankshaft and the casing, between the edges of the front bearing cover and the casing. Then you need a cork gasket, lightly coated with grease, put it on the contact surfaces of the casing and the bearing cover. This seal is lubricated with sealant at the rear edge of the crankshaft rear bearing and between the front edges of the front bearing cap.. The rest of the steps are the reverse of the disassembly. Finally, fill the engine with oil.
