Sump - removal and refitting
Removal
1 Disconnect the battery earth lead.
2 Drain the engine oil.
3 Unbolt and remove the starter motor.
4 Unbolt and remove the cover plate from the clutch housing.
5 Unscrew the plastic timing belt guard from the front end of the engine (two bolts).
6 Unscrew the sump securing bolts progressively and remove them.
7 Remove the sump and peel away the gaskets and sealing strips.
Refitting
8 On the earlier four-piece gasket arrangement, make sure that the mating surfaces of the sump and block are clean, then fit new end sealing strips into their grooves and stick new side gaskets into position using thick grease. The ends of the side gaskets should overlap the seals. Offer up the sump, taking care not to displace the gaskets and insert the securing bolts.

Tighten the bolts in two stages to the final torque given in the Specifications. Fit the timing belt guard.
9 In April 1985, a modified sump and onepiece sump gasket were introduced to improve sealing in the region of the oil pump and rear oil seal carrier- to-cylinder block joints. Removal and refitting procedures are essentially the same as for the earlier fourpiece gasket arrangement but note the following when refitting: a) The gasket should be fitted dry but jointing compound should be applied to the oil pump and rear oil seal carrier-tocylinder block joints as shown.

b) To aid installation , it is helpful if a few studs can be screwed into the retaining bolt holes on each side to locate the gasket as the sump is fitted. As the sump is placed in position make sure that the spacing pips in the sump face locate in the holes in the gasket, then fit the retaining bolts finger tight.
Ensure spacing pips and gasket holes (inset) engage when fitting modified

Remove the studs and fit the rest of the bolts.
c) Tighten the bolts evenly in two stages to the specified torque.
Note that the one-piece gasket can be fitted to earlier engines provided that it is used in conjunction with the modified sump.
