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.

Sadly Dominic it was a combination of leaving a busy multistorey and the Cambridge rush hour! 😮 Had to resort to forcing my way out onto a box junction in the end as nobody wanted to either obey the rules of a box junction or let me out. Nice long walk with the dogs and a close friend this afternoon then she treated us to fish and chips for dinner (saved me cooking) and a nice relaxing evening after. Just taken her and her hound home until tomorrow at least. Hoping for a warm, dry day tomorrow and the energy and enthusiasm to make a start on the Honda. That's about as close as i'll get to relaxing! On a slightly more positive note, i topped the coolant on the Jag and it warms up inside quicker now and the hot idle is more stable (not unexpected to be honest) but a nice side effect of the more stable idle is less of a thump as i engage reverse after driving. Hope you have a good weekend!
