On cars with the above engine numbers and onwards, a modified crankshaft rear cover assembly (Part Number C.16317) with an eccentric oil seal groove is fitted at the rear of the cylinder block.
In conjunction with the modified rear cover a new cork/rubber seal (Part Number C.16315) is fitted.
For cars with engines prior to the above numbers, modified cork/rubber seal (Part Number 2302/S) and sump gaskets (Part Number C.16319) have been introduced.
Sump seals, gaskets and rear cover assemblies should be fitted in accordance with the following details:
| Engines up to above numbers | Engines on and after above numbers | |
| Cork/Rubber Seal | C. 2302/S ( $ 7\frac{7}{8} $" x 23/32" x 7/32") | C. 16315 ( $ 8 $" x $ 2\frac{1}{2} $" x 7/32") |

9 TO 1 COMPRESSION RATIO PISTONS (XK.150 and 3.4 litre models)
| Models affected | Commencing Engine Numbers |
| XK.150 (3.4 litre engine) | V.7524 |
| XK.150'S' (3.4 litre engine) | VS.2195 |
| 3.4 litre Mark 2 | KG.2807 |
On cars with the above engine numbers and onwards 9 to 1 compression ratio pistons with domed crowns are fitted replacing flat top pistons.
The domed crown piston (Part No. C.16339) can be used to replace the flat top piston (C.10649) provided a complete set is fitted. If it is desired to replace a single 9 to 1 compression ratio piston or 3.4 litre engines prior to the above numbers only Part number C.10649 must be used.

CRANKSHAFT DAMPER IGNITION TIMING MARKS
Models affected
A11
The top dead centre mark on the front face of the crankshaft damper is now continued on the edge of the damper to facilitate tuning the engine by means of Crypton "Motormaster" or similar testing equipment, the use of which we encourage.

PAPER ELEMENT AIR CLEANERS
Models affected
3.4 litre Mark 2
3.8 litre Mark 2
Mark 1X cars for certain export countries (replacing oil bath air cleaners)
Note that the above models, originally fitted with an oil bath type air cleaner, are now fitted with a paper element type air cleaner. (This does not apply to the 2.4 litre Mark 2 model which retains an oil bath air cleaner.)
No maintenance is necessary but the element (Part number C.16484) should be renewed every 10,000 miles (16,000 km) or more frequently in dusty territories.
This type of air cleaner is fitted on top of the cylinder head. To gain access to the element, unscrew the wing nut and remove the washer and top cover; the element can now be lifted out.
When replacing the element, ensure that it is seated correctly in the bottom plate. Also check that the rubber sealing ring between the bottom plate and the base is correctly fitted, otherwise air will by-pass the cleaner element.
DISTRIBUTOR DRIVE GEAR END-FLOAT
Models affected
A11
The minimum end-float of the distributor drive gear has been increased from .003" (.07 mm) to .004" (.10 mm) by reducing the thickness of the thrust washer.
/Cont...
It is important when assembling the drive gear to check the end-float and ensure that it is not less than .004". If the end-float is found to be less than this figure, the phosphor-bronze distributor gear should be examined for signs of indentation by the shoulder of the drive shaft. If indented, a new distributor drive gear should be fitted. Otherwise, the thrust washer can be reduced in the thickness by rubbing down on a piece of emery cloth placed on a surface plate.
Amendment to the 2.4/3.4 litre Service Manual
On page B.24 under the heading "Fit Distributor and Oil pump drive gear" amend end-float to read .004" to .006" (.10 to .15 mm).

SPARKING PLUGS RECOMMENDATION - U.S.A., CANADA AND MEXICO
Models affected
Mark 1X, 8 to 1 compression ratio
3.8 litre Mark 2, 8 to 1 compression ratio
3.4 litre Mark 2, 8 to 1 compression ratio
XK.150 (3.4 litre), 8 to 1 compression ratio
XK.150 (3.8 litre), 8 to 1 compression ratio
Note that for the U.S.A., Canada and Mexico Champion N.8 spark-ing plugs are recommended in place of N.5 type for the above models.
It must be noted however that N.8 type sparking plugs must NOT be used on 9 to 1 compression engines, XK.150 'S' or 2.4 litre engines.
REBORING AND FITTING CYLINDER LINERS
(3.8 litre engines)
3.8 litre engines are fitted with cylinders liners in initial production. Reboring of the cylinder liners is permissible up to a maximum of .030" (.76 mm); oversize pistons are obtainable in +.010", +.020" and +.030" (+.25 mm, +.51 mm and +.76 mm) size by quoting /10, /20 or /30 after the part number of the standard size piston.
After the engine has been rebored to +.030" (+.76 mm), or if the bores will not clean up at .030", it will be necessary to replace the cylinder liners, bore out to standard and fit standard sized pistons.
The worn liners must be pressed out from the $ \underline{\text{bottom}} $ using a stepped block (see illustration).
Before fitting the new liner lightly smear the cylinder walls with jointing compound at a point half-way down the bore and also smear the top outer surface of the liner.
Press in the new liners from the top and
