General information
Engine repair procedures - 1.05 and 1.3 litre pre August 1985 / General information

The 1.05 and 1.3 litre engines are of four-cylinder, in-line, overhead camshaft type, mounted transversely at the front of the vehicle. The transmission is attached to the left-hand side of the engine.

The crankshaft is of five bearing type and separate thrustwashers are fitted to the central main bearing to control crankshaft endfloat.

The camshaft is driven by a toothed belt which also drives the coolant pump. The toothed belt is tensioned by moving the coolant pump in its eccentric mounting. The valves are operated from the camshaft by rocker fingers which pivot on ball-head studs. The distributor is driven by the camshaft and is located on the left-hand end of the cylinder head.

The oil pump is of the eccentric gear type driven from the end of the crankshaft.

The cylinder head is of crossflow design, with the inlet manifold at the rear and the exhaust manifold at the front.

The crankcase ventilation system is of the positive type and consists of an oil separator on the rear (coolant pipe side) of the cylinder block, connected to the air cleaner by a rubber hose. Vacuum from the air cleaner provides a partial vacuum in the crankcase and the piston blow-by gases are drawn through the oil separator and into the engine combustion chambers.
