    I didn't think it would be long before this issue raised its ugly head, but behold, split cam covers and throttle body strike again... I posted this previously in the XF section before i drowned her, and now the XJ has the same... A word for the wise.. A replacement paper air filter from JLR is £25, do not be tempted to go for a K&N reusable filter thinking that you can save on the annual cost of a throw away item... its contaminated my MAF sensor, Bank 1, throwing up fault codes and RP every day, although the underlying issue of the split cam covers is yet unresolved. A quote from JLR that is akin to selling a kidney, however from experience it is not a hard job to do if you don't mind a little obscure modification to the fuel rail bracket in order to get the last remaining cam cover bolt off... All in all, the last outing took me 4 hours (with fastidious cleaning included) and cost me the price of the Bank 1 cover @ £218 and 3 injector seals at £2. For anyone experiencing the same, tell tale signs of imminent or actual failure are Restricted Performance on the dash, the above mentioned error codes and a build up of oil under the throttle body housing, directly above the coolant pipe assy between the banks. You cannot fix the issue as its a poorly made (probably part French) plastic welded part. The older more susceptible parts start with 4S7Q part numbers, whereas the revised later part starts with a 9. I am contemplating taking the failed part to my local engineering guy and getting him to build me an aluminium 'cap' to replace the plastic version - This would simply clip on with a large rubber O ring and hopefully stop any repetition. Cam covers are now on their 11th revision and are visibly different on the top section as opposed to the factory fitted 2009 - 2012 versions. New Cam covers come with the required gaskets. Injector removal requires a little dexterity and patience and contrary to popular belief, the high pressure lines can be reused once , saving another £145 from any potential bill. Oil residue between the banks was dealt with a liberal spraying of Gunk (in a spray bottle) - Aerosols tend to spray everything everywhere you do not want it. Then removed the resulting sludge with the wife's brand new Wet & Dry vacuum cleaner. I can safely report back that i shared my success with her, and she has appointed her solicitor as a result and i have forgotten just how soft the Sofa is to sleep on...
