Welcome aboard David! I'm on my 3rd Jag now (1999 S Type) and i doubt i'll go back to another make now. Everyone on here seems friendly and helpful, hope you enjoy your XKR!

Sounds like a normal diesel to me! 😛 Seriously, diesels accelerate by overfueling as the amount of air entering the engine isn't restricted with a throttle butterfly like in a petrol. It may be it needs an Italian Decoke which would burn excess sooty deposits from the exhaust which can contribute to black smoke from the exhaust under aceleration and some injector cleaner may help too. https://www.halfords.com/motoring/engine-oils-and-fluids/fuel-and-oil-additives/comma-diesel-magic-400ml-264671.html I've heard good reports in the past few years about that stuff and used it myself about 20 years back in a diesel works truck. If you keep your eyes peeled while out and about, you'll no doubt see someone giving a diesel the beans andyou should see a similar black cloud from their tailpipe(s), remember when comparing it to yours that it always looks worse in your mirror than from someone elses car. There could be other reasons such as a previous owner has had it chipped, turned the boost up or similar, all of which would result in bigger clouds of black under hard acceleration while still allowing an MoT pass.

Rock and hard place come to mind! 😮 If you buy a replacement head (cost???) then you get the car up and running in a saleable condition. If you then provide the original head to the new owner to do with as they think fit (get it repaired and fitted to the car for originality or polish it and use it as a garage ornament or just plain junk it) then i don't see the value being reduced. Also here in the UK, we're not quite as focussed on "all matching numbers" as it seems our stateside cousins are. With this in mind, in the UK it wouldn't make any difference unless someone really wanted originality and even then, there's no way the car could be truly original at 60+ years old. Tyres, brake parts, the list is long of parts that wear out and besides, after a full restoration, it would be unlikely the engine would be original to most 60 year old UK cars. What are the costs of having the original head repaired with guaranteed work and how does that compare to the cost of the replacement head? If those costs are similar then the answer is fairly simple, get the existing head repaired and fitted, this would satisfy the "matching numbers guys" and not really cost more. I can't really comment on the value decrease for the reasons above, however i do know from having watched things like Counts Kustoms and similar that in the USA a premium is usually applied to the price when selling a matching numbers car and is normally paid happily by the buyer for that provenance. Not much fact-based arguments above, more like based on what i feel is a common-sense approach to your dilemma but hopefully you can take something from it and make a decision.

Check your wiring to the CPS, might also be worth unplugging and spraying contact cleaner into the plug and the sensor contacts, refitting/unplugging a few times then a final squirt on both with contact cleaner before final connection and then reset again on the OBD, see if that improves matters. If not, renew the sensor. I know when the CPS went on mine it was a non-starter and no fault code thrown either! 😮

A Happy New Year to all on here! Hope it's much better than 2023 was! 😉 😄

Crank sensors either work or they don't, no half measures. I'm guessing it's a non-starter? If so, replacement is the only real option. https://www.ebay.co.uk/itm/125200276397 I believe that's the correct one for your car but double check as you haven't provided many details about your car.
