Cylinder head - refitting

Engine repair procedures - 1.6 and 1.8 litre 8 valve / Cylinder head - refitting

Note: New cylinder head retaining bolts must be used on refitting
1 Clean the top face of the block. Clean and inspect the bores and lubricate them with clean engine oil. Turn the crankshaft so that the pistons are in the mid-cylinder position.

2 The engine number is stamped on an inclined surface between No. 3 and No. 4 cylinders on the side above the distributor.

Using this as a datum, install a new cylinder head gasket so that the word ‘OBEN’ on the gasket is over this datum point and on the top side of the gasket (see illustration).

3 Lower the cylinder head into position, locating onto the centring pins where fitted (see illustration). If the cylinder block does not have centring pins, initially refit new No. 8 and No. 10 cylinder head bolts. Do not use jointing compound. Check that the gasket is seating correctly and fit the remainder of the new bolts. Following the sequence shown, tighten the bolts until the head is firmly held.

Using a torque wrench, tighten the bolts in stages to the specified torque following the same sequence (see illustration).
