Engine in-car repair procedures / General information

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.

Major operations possible with the engine in the car
5 The following operations can be carried out without having to remove the engine from the car:
a) Removal and servicing of the cylinder head, camshaft, and timing belt’.

b) Removal of the flywheel and clutch (after removing the gearbox).

c) Renewal of the crankshaft front and rear oil seals.

d) Removal of the sump.

e) Removal of the oil pump.

f) Renewal of the engine mountings.

Major operations only possible after removal of the engine from the car
6 The following operations can only be carried out after removal of the engine from the car:
a) Renewal of the crankshaft main bearings.

b) Removal of the crankshaft.

c) Removal of the pistons/connecting rods.

*Cylinder head dismantling procedures are detailed in Chapter 2B and contain details of camshaft and hydraulic tappet removal.

Note: It is possible to remove the pistons and connecting rods (after removing the cylinder head and sump) without removing the engine from the vehicle. However, this procedure is not recommended. Work of this nature is more easily and thorough/y completed with the engine on the bench, as described in Chapter 2B.
