    ... Nice body but bad breath

    After my last Jag adventure and having sold both the Sandrail and the SAAB I have been on the look out for a new project (not counting the electric buggy or the 63ft steel boat of course :whistle: )

    I get the opportunity to buy a rather nice '97 Jag XK8 at a good price as it needs a bit of a tidy up. Only worry was it is not really that broken, just a bit unused and with a dent. The seller (that I know and trust) kindly took it for an MOT which we were both expecting it to breeze through based on it's last one (a while back), a general inspection and good service history.

    Nope. Fails on welding, sticky calipers, and a bearing - all mundane stuff, BUT much more excitingly it also had a major emissions fail - the MOT garage said they thought it needed 2 new cats :o.

    A revised agreement was reached and I get it next week via trailer, ferry and transporter, the welding having been done by the very professional seller.
    Meanwhile I am happily warming up the oscilloscope and diag tools for another venture into broken Jag land :laughing:

    Italian Tune-up?
    If it has one of those whiny whirlygigs attached though beware!
    A while back I was tasked with getting No 2's Daimler SuperV8 back on the road. Did a full service, pad and disc change and was taking it for its MoT. Went via a local bypass to ensure it was warmed up but was held back by the 'limp home' mode. That limited it to a mere 3000rpm. Any idea what 3000 rpm is on one of those? Well past 'within ACPO limits' officer.

    As it turned out I'd forgotten to attach the airflow sensor when changing the air filter. It passed.[/QUOTE]

    Be prepared for the headliner to drop.

    Nope, no whiny whirlygig, Did think about it but a suitably broken one (XKR) did not come up at the right time.

    Roof liner has usually gone by now, it's got a lot of expensive history so I will be taking a look to see it ot has been done.

    Hope not, they are Iridium ones made from sintered unicorn poo and £60 for a set!

    Having studied the emissions sheets and heard how it drives I have my own theory about the issue. I'll put it out for discussion and educated guessing on Monday - the day before I get the car!

    Keep the welder handy - there will probably be more rot than that which failed MOT which isn't testable

    Right so these are the V8's emissions, the seller's garage said it needs two new cats and I bought it with that possibility in mind.
    I will not have the car until Tuesday so don't have the fuel trims or further info. I am assured by the seller that it runs smoothly - and I have no reason to doubt him.

    I love a good car puzzle so I have written up what I think the problem is and why but it will be interesting to see what others think for some diagnostic entertainment - if you like that sort of thing.:laughing:

    Hmmm, is that a single fuel rail, or two, or no fuel rail just a reg in the tank? Looks like an issue with one side anyway, dumping fuel in?

    Could be failed/failing O2 sensors causing the engine management to dump in too much fuel, not good long term for the cats.

    ...did you say rust? That's been a running battle on mine since I bought it, pretty much one big welding job every year since 2014.

    Pics of underneath show a bit of surface rust and dire need for waxoyl/dinitrol, also that at least one of the footwell plates has been done.

    Have you had a chance to look behind the upright on the front subframe? It's a 3 or 4 layer rust sandwich there, ludicrous design.

    There is much more, the rust just goes on, and on and on.........

    Hope you have got a good one.

    That is extraordinarily bad for something that can't be more than 24 years old. Previous owner lived on Lindisfarne and couldn't read a tide table?

    More seriously did it live right on the sea front, or do they all do that sir?

    (waits to be told you live on the Esplanade somewhere)

    Thanks @RaceDiagnostics , think I have read most of those - really helpful for knowing how it's put together- I am thinking that your environment does have an impact though, fortunately I am waaaay down south. :waving:

    Sure I'll get to rust later (arches and a dent for a start!) - in the meantime... emissions - anyone else taking a stab at it ?

    It was only 10 years old when I bought it, with 10 jag service stamps, a 2002 car, spent it's life in Edinburgh. Looks great but truly crap quality.

    Your right, it's the road salt that kills them.
