    Xk X150 service

    Hi all
    Just bought my first xk 2007 x150 and doing a full service on it.
    Got a couple of questions if I may.
    Is there a fuel filter fitted and if so where is it fitted ??
    Found the air filter and after an awful lot of wurth penetrating oil and patience finally got the seized in spark plugs out, which looked like they had been in there an awful long time!
    Also in park is there a rev limiter over 4000rpm ? As if there is not I have a bad misfire after 4000rpm !
    Didnt notice or rev it that high before I changed the plugs.

    Hiya Dobsy and welcome to the forum,

    You're question is not really "forum news" though, so it's probably be best if you posted in the X150 part of the forum:
    2000 Jaguar X308 4.0
    1969 Jensen Interceptor Mk I 6.3 litre

    Welcome to the forum Dobsy.

    Not sure on the 4.2 but if there is a fuel filter it may well be in the tank. The rev limiter should kick in around 3000revs and yes, it does feel like it’s missing.

    Dont forget to change the pollen filter also.

    Here is the service manual for your car,
    2012 XKR Black pack, Speed Pack, Aero pack, Rat pack. Past:-87'XJS 3.6L, 93'XJ40 3.2L gold, 95'XJ6 4.0L sport, 00'XJ8 3.2L sport, 2005 XK8 4.2L coupe, 2009 XK 5.0L Portfolio in that order and enjoyed all of 'em.

    I do not offer advice, I only say what I would do with the set of circumstances presented. Your choice always.
