Cylinder head - inspection

Cylinder head - inspection

1. Inspect cylinder head for signs of damage.

2. Check cylinder head for warping, across centre and from corner to corner. Maximum warp = 0.10 mm

CAUTION: Cylinder heads may not be refaced, replace head assembly if warping exceeds figure given.

Refit

1. Clean mating faces of cylinder head and block. Clean oil and coolant passages. De-carbonise piston crowns and cylinder head if necessary.
2. Clean dowels, dowel holes and cylinder block bolt holes.

3. Check that oil feed restrictor in cylinder block is clear and fitted below cylinder block top face.
4. Clean and dry cylinder head bolts.

5. Measure length of cylinder head bolts. if any bolt exceeds the maximum length of 243.41 mm, then all bolts must be renewed.

CAUTION: Do not remove washers from bolts, keep bolts in their fitted order.

6. Temporarily fit crankshaft pulley bolt, remove timing pin 18G 1523 and using crankshaft pulley bolt, rotate crankshaft anti-clockwise until numbers 1 and 4 pistons are approximately 25 mm below cylinder block top face. Do not remove pulley bolt at this stage.

CAUTION: Ensure timing belt is not trapped as crankshaft is rotated.
