Engine in-car repair procedures

Engine in-car repair procedures

1 The engine is of four cylinders, in-line, overhead camshaft type mounted transversely at the front of the car, with the gearbox on the left-hand side. The top of the engine is inclined slightly forwards.

2 The crankshaft is of five bearing type, and the centre main bearing incorporates thrustwashers to control crankshaft endfloat.

3 The camshaft is driven by a toothed timing belt from a sprocket on the front of the crankshaft, and the timing belt also drives the water pump. The valves are operated by hydraulic tappets. The cylinder block is of cast iron and the cylinder head of light alloy.

4 The geared oil pump is located on the front of the cylinder block and driven by the crankshaft via a chain. A positive crankcase ventilation system is incorporated.
