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. The pistons are attached to the connecting rods by gudgeon pins which are an interference fit in the connecting rod small-end [...]

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. These marks do not indicate TDC. U[...]

Fit all bolts, finger-tight. 14 Tighten the cylinder head cover bolts in the sequence shown to the specified torque wrench setting (see illustration) . 15 Refit the timing belt upper right- hand/outer cover to the cylinder head cover and tighten all the di[...]

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. If this is the case, the cover can be slotted to ease future removal and refitting (see illustration[...]

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. Take care not to distort or damage the cover or th[...]

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. Work only as described to impose the pressure of the valve spring[...]

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. 2 On most older engine designs, this meant that the valve clearances (also known as [...]

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. 18 Further to the warnings given in[...]

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. If any bolt is overtightened past its mark, slacken it through 90°, then re- tighten until the marks align (see i[...]

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. After reasse[...]

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. During an overhaul, the cylinder liners[...]

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. 13 From underneath the vehicle, pull out the rubber retaining pin [...]

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. Note: Be sure to perform all the f[...]

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. With a semi-rotary action, grind the valve head to its s[...]

Discard the sealing ring (see illustration) . 8 Unscrew the two retaining nuts and remove the oil rail (see illustration) . 9 Using a hammer and centre punch, paint or similar, mark each connecting rod big-end bearing cap with its respective cylinder number on the fl[...]

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. 11 With Nos 2 and 3 cylinder big-ends disconnected, repeat the procedure (exe[...]

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 shells, which must be kept with their correct respective partners from the main bearing ladder so that all shells can be identified and (if necessary) ref[...]

Insert each liner into the cylinder block/crankcase, taking great care not to displace or damage the sealing rings, and pr[...]

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. 8 Using a micrometer, measure the diameter of the main bearing and crankpi[...]
