The crankshaft runs in five main bearings. Thrustwashers are fitted to the centre main bearing (upper half) to control crankshaft endfloat. The connecting rods rotate on horizontally- split bearing shells at their big-ends.
4 Top Dead Centre (TDC) for number one piston - locating 2 General 1 The crankshaft pulley, crankshaft and camshaft sprockets are provided by the factory with clear marks which align only at 90° BTDC. This positions the pistons half-way up the bores so that there is no risk of damage as the engine is reassembled.
13 Refit the cover to the cylinder head, ensuring that the seal remains seated in its groove. Fit all bolts, finger-tight. 14 Tighten the cylinder head cover bolts in the sequence shown to the specified torque wrench setting (see illustration) .
2 Unscrew the remaining cover retaining bolts and withdraw the cover, noting the rubber seal fitted to the mounting bracket edge. Note that if the cover is not slotted at the bottom corner screw’s location, the screw will have to be removed fully.

loose fit in the camshaft end, remove it and store it with the sprocket for safe-keeping. Crankshaft sprocket 13 On K16 engines, use the tool described in paragraph 11 to lock together the camshaft sprockets so that they cannot move under valve spring pressure when the timing belt is removed.
Tensioner pulley 39 Refit the tensioner pulley assembly and tighten the pulley Allen screw and the backplate clamp bolt lightly. Hook the tensioner spring over the pillar bolt and check that the tensioner is free to move under spring tension and that the pulley bears correctly against the timing belt (see illustration) .

time to refill with oil on restarting the engine, resulting in incorrect valve clearances. K16 engines 9 Remove both camshaft sprockets, then unscrew the inner cover’s upper retaining bolts so that the cover can be pulled away from the cylinder head just far enough for adequate working clearance.
29 Working in the sequence shown (see illustration) , progressively tighten the camshaft bearing cap bolts by one turn at a time until the caps touch the cylinder head evenly. Now go round again, working in the same sequence, and tighten all the bolts to the specified torque setting.
12 Valve clearances - general information 1 It is necessary for a clearance to exist between the tip of each valve stem and the valve operating mechanism. This allows for expansion of the various engine components as the engine reaches normal operating temperature.
the cylinder block/crankcase as it is located by dowels as well as by the tops of the liners. 17 With the joint broken, lift the cylinder head away, using assistance if possible as it is a heavy assembly, especially if complete with the manifolds. Remove the gasket, noting the two locating dowels, and discard it.
tightens each bolt through half a turn so that the marks face away from each other and the third stage tightens them through another half-turn so that all the bolt-head marks will then align again with their cylinder head counterparts.
area so that it cannot be contaminated with oil. 2 Drain the engine oil, then clean and refit the engine oil drain plug, tightening it to the specified torque wrench setting. 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.

Unbolt the mounting bracket from the gearbox and the connecting link from the underbody bracket, then remove the mounting (see illustrations) .

Loss of power, rough running, knocking or metallic engine noises, excessive valve gear noise and high fuel consumption may also point to the need for an overhaul, especially if they are all present at the same time. An engine overhaul involves restoring all internal parts to the specification of a new engine.
12 Trace the clutch cable back from the clutch release lever to the bulkhead and remove the C-clip which retains the outer cable spring in position. Unhook the inner cable from the release lever and free the outer cable from its mounting bracket and position it clear of the gearbox.

similar small container (see illustration) . Note that No 1 valve is nearest to the timing belt end of the engine. 7 Cylinder head and valves - cleaning and inspection 4 Note: If the engine has been severely overheated, it is best to assume that the cylinder head is warped and to check carefully for signs of this.
even the renewal of the valve or seat insert is required. 14 Valve grinding is carried out as follows. Place the cylinder head upside down on a bench. 15 Smear a trace of (the appropriate grade of) valve-grinding compound on the seat face and press a suction grinding tool onto the valve head.
7 Remove the sump and unbolt the oil pump pick-up/strainer pipe from the oil rail. Discard the sealing ring (see illustration) . 8 Unscrew the two retaining nuts and remove the oil rail (see illustration) .
push the connecting rod up and off the crankpin, ensuring that the connecting rod big-ends do not mark the cylinder bore walls, then remove the upper bearing shell. Keep the cap, bolts and (if they are to be refitted) the bearing shells together in their correct sequence.
10 Remove the crankshaft (see illustration) . 11 Withdraw the two thrustwashers from the No 3 main bearing upper location. Noting the position of the grooved shells, remove the upper main bearing shel.

bearing journals for uneven wear, scoring, pitting and cracking. 6 Rub a penny across each journal several times. If a journal picks up copper from the penny, it is too rough (see illustration) . 7 Remove any burrs from the crankshaft oil holes with a stone, file or scraper.
16 Engine overhaul - reassembly sequence 1 Before reassembly begins, ensure that all new parts have been obtained and that all necessary tools are available. Read through the entire procedure to familiarise yourself with the work involved and to ensure that all items necessary for reassembly of the engine are at hand.
Main bearing running clearance check 7 Clean the backs of the bearing shells and the bearing locations in both the cylinder block/crankcase and the main bearing ladder. 8 Press the bearing shells into their locations, ensuring that the tab on each shell engages in the notch in the cylinder block/crankcase or main bearing ladder location.
assemblies (see illustrations) . Leave No 1 and 4 cylinders at the TDC position 25 Thoroughly degrease the mating surfaces of the cylinder block/crankcase and the main bearing ladder. Apply the special Rover sealant to the mating surface of the cylinder block/crankcase as shown (see illustration) .
33 Refit the dipstick tube to the cylinder block/crankcase, tightening the bolts to the specified torque wrench setting. 34 Refit the timing belt inner cover, the sprocket(s) and tensioner, and the belt itself. 35 Using a torque wrench, check that the amount of force required to rotate the crankshaft does not exceed 31 Nm.
13 Lubricate the cylinder bores, the pistons and piston rings, then lay out each piston/connecting rod assembly in its respective position. 14 Starting with assembly No 1, make sure that the piston rings are still correctly spaced, then clamp them in position with a piston ring compressor.
20 Engine - initial start-up after overhaul 2 1 With the engine refitted in the vehicle, double-check the engine oil and coolant levels. Make a final check that everything has been reconnected and that there are no tools or rags left in the engine compartment.
