Ticking Time Bomb

The original part will only be a template - the critical sections of the part is the mounting points to the engine the distance in between them, any offset of the mounting points to the engine (if any), mounting point for the sensor, the internal dimensions to make sure you don't introduce the need of more fluid and that's about it. Everything else can be re-done and re-shaped as wished.
Also, you will need to take the thing apart anyway - you need to see if there are any kind of special channels inside of it that could affect the flow of the liquid in any way.
An old, used part will work just fine.
I think you should go off a new part for your mold. I have experienced two split pipes and the splits occurred in different places. I don't believe you will get any useful insights from a busted unit. The pipe just splits wherever the weakest point in the seam is. IF you do decide to make these, I would get in line all day for an aluminium one.

I'm not the one who asked for it... I was only explaining the process and why a new part is not necessarily needed.

I just hope it gets done. It would be a great thing for all Jag owners who have these pipes. Ever since the first one busted I have been paranoid about it. Not that the part is expensive, but it really causes alot of stress in the back of your mind. I hope the guy gets one and does the build-out for it.

I sure have replaced a bunch of old plastic car parts that were not quite the same shape as the new one. Often the only thing keeping an old plastic part's shape is the other parts they are bolted to. But I was imagining trying to replicate a nearly identical part, just cast in a superior material. If the only critical measurements needed are the flanges that attach it to the motor, then those portions may be robust enough hold their form.
If I were trying to do this project as a one-off, I wouldn't use a lot of measurements anyway, rather, I'd probably proceed like I did with a couple of turbo conversions of other cars. I had the motors out of course which made it easy to do iterative test fitting. What I did for oil and coolant supply to/from the turbos was to cut off the flanges from other factory tubes, discard the factory hard piping and weld bungs on the flanges to attach other type fittings. Then I connected everything up between the engine and turbo with braided hose. Unfortunately here the Jaguar's nylon flanges can't be cut off and welded in the same fashion, but instead, I'd probably be able to mill out suitable flanges on my Smithy. Then perhaps like I built my intercooler piping, I could order some mandrel-bent tubing sections in various angles, maybe a flexi-pipe section in the middle, cut and tack weld them together to form the hard pipe section. I'd attach the flanges to the motor, tack weld the pipe section to the flanges to ensure fit, then unbolt the whole affair and have it all professionally welded to ensure it was watertight. The downside is all this could not be economically reproduced for resale. Hopefully our volunteer will have a more reproducible solution.

If anyone has kept their failed crossover pipe(s) after replacing them , I would like to get my hands on one or two for reverse engineering them for manufacture in metal. It might also be possible to print them in a material similar to the original but with no seams, as expansion and shrinkage must be taken into account.Just trying to get the project moving , I've been a model maker for over 40 years and this sort of thing is what I live for.
The engineer I work with is up for the idea, and has access to both 3D printing equipment as well as high pressure casting in bronze or aluminum, one way or the other I'm confident we can create a replacement part that will be a better long term solution.

All good constructive discussion....The real problem is finding a part for the V6 SC....I have tried for days and none of the parts suppliers seem to have this little goody, nor do they give a part number for it when warning me that the similar part for the V8 as well as the NA V6 won't fit.Very frustrating , especially now that Brexit looks to be a full crash out, which may disrupt parts supply.
Perhaps Brutal can find me the correct part number for the V6 SC...I have found parts for the V8 at several vendors, don't mind buying one or two for inspection and dimensioning, can't make an omelette, etc;....
Just need to find the silly part for my own 2015 XF Sport V6 SC and I can begin.

@Paul Fisher the part number you're looking for is C2Z18624.
The V8 rear crossover pipe is C2Z31645.
For future reference, there's an online copy of the Jaguar EPC here (requires registration). Sometimes the part numbers are slightly out of date but googling will get you any superseding part numbers etc.

Thanks so much, Dave...Parts ordered and I can't wait to get started on this, it will be great to have a project to sink my teeth into, first real job since the fire.All I've been doing is lists of contents for insurance companies...Not fun.This, however will be a challenge. One way or t'other I am going to figure out how to make us a bullet proof crossover pipe.

So funny!

Did you even spend any time checking the site before running your mouth as usual?
It makes no odds to me what site you use, but I'm going to call out BS when I see it.
For example, here's the part Paul Fisher was trying (and failing) to find:
What's that at the bottom if not a diagram?

@Paul Fisher - strongly suggest to start your own thread if you start doing this - will be much easier to follow and a more appropriate thread name.

Yes, I got the parts, one for the V8 as well as one for the V6, the difference is amazing. I've sent them off my friend Ernie the scanning/3D printing specialist and have heard nothing back, but that's Ernie. I will ping him and see what gives, he's either enthralled at the challenge or gone into a sulk.
One never knows....

May I ask, am I correct that NO FIX to leaking plastic hoses are available? I am into buying used F-Type V6S as my dream car and reading for months on this forum this is the only issue that is making me reconsidering the purchase. Basically we all know that all cars have something, but here even the water pump is a new design, supercharger spring can be replaced by fixed etc... But this is seriously like a ticking bomb if as little as 20k miles can destroy the lines and in worst scenario you will be trapped somewhere thousands of miles from home or with dead overheated engine. I wouldn't mind to replace all the lines, but it seems to me that there si no improved design/solution? Thank you!

Have your car checked out ahead of purchase, do a PPI with a reputable mechanic, and enjoy your car.
