Engine in-car repair procedures / Sump - removal and refitting

Removal
1 Disconnect the battery negative cable, then carry out the following operations: a) Apply the handbrake, chock the rear wheels, then jack up the front of the car and support it on axle stands - refer to the Reference Chapter for greater detail.

b) Refer to Chapter 8 and disconnect the right-hand side driveshaft (Chapter 7) c) Refer to Chapter 4C and unbolt the exhaust downpipe from the manifold flange.

d) Unclip the alternator wire from the sump.

e) Refer to Chapter 1 and drain the engine oil into a suitable container. Clean the drain plug and washer and refit it, tightening it to the specified torque.

2 Unscrew the sump bolts, then break the joint by striking the sump with the palm of your hand. Lower the sump away from the engine and withdraw it from underneath the vehicle.

Recover and discard the sump gasket.

3 While the sump is removed, check the oil pump pick-up/strainer for signs of clogging or disintegration. If necessary, remove the pump as described in Section 14, and clean or renew the strainer.

Refitting
4 Remove any remains of the old gasket from the sump and cylinder block - ensure that both mating surface are spotlessly clean. If the gasket has been leaking, check the mating surface of the sump for warpage that may have been caused by over-tightening of the bolts. Renew the sump if it is damaged - do not attempt to repair it.

5 Apply a coating of suitable sealant to the sump and crankcase mating surfaces.

6 Lay a new sump gasket in position on the sump mating surface, then offer up the sump and refit the retaining bolts. Tighten the nuts and bolts evenly and progressively to the specified torque.

7 Refit the drive shaft, exhaust downpipe and alternator cabling.

8 Refer to Chapter 1 and refill the engine with the specified grade and quantity of oil.

9 Restore the battery connection.
