Sump - removal and refitting
SOHC engines / Sump - removal and refitting


Note: New gaskets and sealing strips will be required for refitting, and sealing compound will be required to coat the gasket faces.

Removal
1 If the engine is in the vehicle, proceed as follows, otherwise proceed to paragraph 12.

2 Disconnect the battery negative lead.

3 Apply the handbrake, jack up the front of the vehicle and support on axle stands (see УJacking and Vehicle SupportФ).

4 Drain the engine oil into a container.

5 Remove the starter motor, if necessary.

6 Unscrew the nuts or bolts, as applicable, securing the engine mountings to the crossmember.

7 Working in the engine compartment, unscrew the bolt securing the intermediate shaft to the steering column, swivel the clamp plate to one side, and disconnect the intermediate shaft.

8 Where applicable, detach the brake lines from the crossmember.

9 Support the engine using a hoist, or a bar and blocks of wood resting on the suspension turrets (see illustrations).

Attach the lifting
tackle to the engine lifting brackets on the cylinder head. If using a support bar, the engine may be lifted slightly by using the bar as a lever before resting it on the wooden blocks.

10 Support the front crossmember with a trolley jack, then unscrew the bolts securing the crossmember to the underbody (see illustration).

11 Lower the crossmember just enough to give sufficient clearance to remove the sump (see illustrations).

If the sump is stuck, carefully tap it sideways to free it. Do not prise between the mating faces.

Note that if the engine has been removed, it is preferable to keep the engine upright until the sump has been removed to prevent sludge from entering the engine internals.

13 Recover the gaskets and sealing strips.

14 Thoroughly clean the mating faces of the cylinder block and sump.

Refitting
15 Commence refitting by applying sealing compound (available from a Ford dealer) to the corners of the front and rear rubber sealing strip locations in the cylinder block, then press the sealing strips into the grooves in the rear main bearing cap and the crankshaft front oil seal housing (see illustrations).

16 Apply a little sealing compound to the mating face of the cylinder block, then place the sump gaskets in position, ensuring that the end tabs locate correctly beneath the rubber sealing strips (see illustration).

17 Locate the sump on the gaskets and loosely fit the securing bolts.

18 Tighten the bolts in the correct sequence (see illustration)

noting the two stages given in the Specifications. Tighten to the first stage in a clockwise sequence starting at point УAФ, then tighten to the second stage in a clockwise sequence starting at point УBФ.

Tighten to the third stage after the engine has been running for twenty minutes.

19 If the engine is in the vehicle proceed as follows.

20 Carefully lift the crossmember with the jack, then refit the securing bolts and tighten to the specified torque.

21 Withdraw the jack, then lower the engine and remove the lifting tackle.

22 Where applicable, refit the brake lines to the crossmember.

23 Ensure that the front wheels are pointing straight ahead and that the steering wheel is centred, then reconnect the intermediate shaft to the steering column. Secure the clamp plate with the bolt.

24 Refit the engine mounting bolts and tighten to the specified torque.

25 Refit the starter motor.

26 Lower the vehicle to the ground.

27 Ensure that the sump drain plug is fitted, then fill the engine with the correct quantity and grade of oil. If necessary, renew the oil filter before filling the engine with oil.

28 Reconnect the battery negative lead.

29 Start the engine and check for leaks around the sump, and where applicable the oil filter. When the engine is started, there may be a delay in the extinguishing of the oil pressure warning lamp while the system pressurises.

30 Run the engine for twenty minutes then stop the engine and tighten the sump bolts to the third stage given in the Specifications, starting at the point УAФ shown and working clockwise.

31 Check the oil level.

32 Dispose of any old engine oil safely. Do not pour it down a drain - this is illegal and causes pollution.
