TU petrol engine in-car repair procedures / Sump - removal and refitting


Removal
1 Firmly apply the handbrake, then jack up the front of the vehicle and support it on axle stands (see УJacking and Vehicle SupportФ).

Disconnect the battery negative lead.

2 Drain the engine oil, then clean and refit the engine oil drain plug, tightening it to the specified torque. If the engine is nearing its service interval when the oil and filter are due for renewal, it is recommended that the filter is also removed, and a new one fitted. After reassembly, the engine can then be refilled with fresh oil. Refer to Chapter 1 for further information.

3 Remove the exhaust system front pipe as described in the relevant Part of Chapter 4.

4 Progressively slacken and remove all the sump retaining nuts and bolts. On cast-iron block engines, it may be necessary to unbolt the flywheel cover plate from the transmission to gain access to the left-hand sump bolts.

5 Break the joint by striking the sump with the palm of your hand, then lower the sump and withdraw it from underneath the vehicle (see illustration).

Refitting
7 Clean all traces of sealant from the mating surfaces of the cylinder block/crankcase and sump, then use a clean rag to wipe out the sump and the engineТs interior.

8 Ensure that the sump and cylinder block/crankcase mating surfaces are clean and dry, then apply a coating of suitable sealant to the sump mating surface.

9 Offer up the sump, locating it on its retaining studs, and refit its retaining nuts and bolts. Tighten the nuts and bolts evenly and progressively to the specified torque.

10 Refit the exhaust front pipe as described in the relevant Part of Chapter 4.

11 Replenish the engine oil (see Chapter 1).
