So who really builds the 5.0 engines? Ive got my '10 up on the lift doing some work and also some inspection, and I see FoMoCo stamped more than I do Jaguar! (yes, I know the relationship and the whole story, yada yada)

But my real question is, and maybe I havent searched enough, but isnt it a little too fishy that its a 5.0L that says Ford all over it? So, what aftermarket Ford parts has anyone found to work on the '10 and up XKR engine/transmissions?

 

My hunch is the Ford is just the contract manufacturer and it's all Jaguar/Ford design.

 

Keep in mind that Ford Motor Co sold Jaguar/Land Rover to Tata Motors of India in 2008.

Keep in mind that there was not much change in chassis design or body work from 2007 to 2013.

Thus, it is not unlikely that everyone will see FoMoCo on parts within their own Jaguars. I am quite sure that a surplus of FoCoMo parts were available to Tata after they acquired the brand. Tata (Jaguar) would become the owner of those surplus parts so why not use them.

As for the engines, I am under the impression that they are assembled by Jaguar in a separate factory in the UK. As for the components of the engine, I am sure that several parts and internals are outsourced for Jaguar.

It's still a Jaguar, and really if FoCoMo bothers you, what's your thoughts and ideas of the Jaguar and Land Rover brands being owned by an Indian corportion.

I have learned that my under the hood plastic fasteners that hold down most of the plastic covers around the engine are FoMoCo parts and actually were ordered from the Lincoln brand and part number. So I guess we have a little bit of Lincoln in the Jags.

Don't let the small stuff get to you. It still took 2 weeks to build your Jaguar, 60% robotics and 40% hand built. I had a 2012 Chevrolet Camaro RS built for me in Canada, and it only took 1 day to build it.

 

After pulling the 5.0L engine out from the 2010 XKR that I just bought, both my mechanic and I were quite surprised to see the FoMoCo on every part of the engine including the block. So, obviously Ford still plays a major role in Jaguar's existence even under Tata.

 

Actually, the relationship with Ford was a major deciding factor into buying the XKR. I couldnt find an American "supercar" that I liked, and Ive always liked Ford (especially Lincoln) but unfortunately at this point in my life I cant afford my dream car, the Ford GT.

Anywho, the purpose of this thread was really to find out if anyone has had any successful aftermarket, or even OEM parts that work on the Jag whether it be for upgrade or repair/replacement.

 

The engines are made in the Ford Bridgend engine plant, in a separate room, for JLR.

So "made by Ford" but "engineered by Jaguar" but it's not actually a Ford engine and you won't find any aftermarket parts to suit.

Lots of parts are sourced in the Ford supply chain, and will be for a while yet.

My Land Rover has a Volvo engine, and the ECU file is written by Volvo, it was part of the family at that time. Don't let it get to you...

 

Dont let what get to me? The curiosity of parts interchangeability?

 

That there is no parts interchangeability...

 

As stated by other members, some parts like fasteners are actually ordered as Ford/Lincoln part numbers, so there IS some interchangeability. Im wondering what else could, for a multitude of reasons.

 

Actually Ford saved Jaguar and built it to what was when sold to Tata. In fact Ford fixed the problems at Jag upgraded and then sold it for what they paid for it. The Jaguar brand is Jag made in England, yes 2 weeks to build, but it is a JAGUAR. If one had researched the brand, all this and Fords input after the sale would of been found out. Research before buying.

 

If one were to study the history of American block castings, you would quickly come to realize much of the preexisting cast is still used, with only minor changes to the molds themselves. I have "lineage" charts showing the big three continuously reused casts with minor deck , bore and accessory mount point changes for an easy 10 to 15 years of production run, providing a vast array of displacements and power outputs, all born from a cast made over a decade earlier.
Knowing that, it is theoretical that the Jag 5.0 could retain many Ford underpinnings... Wouldn't it be great to find the water pump has a Ford equiv, or maybe the oil pump with Ford motorsport parts?

I think the OP's question is not only valid, but interesting from the technical side as well.

 

This is something I've wondered about as well. If you do some digging on information on our engines the block has been used by Ford. I have to go back and find where I read this but if thats the case a few other parts may be as well. Or I may be totally wrong, as it may be a base Ford block modified per jaguars specs.

This happens a lot in the supercar world where a builder will go to BMW or Mercedes and have them build an engine to their specs. It may still be badged a Merc or BMW but can be quite different internally.

 

There is something about blocks that makes them VERY long lived. They're tweaked in many ways yet also in many ways the same. I guess if it ain't broke don't fix it. Plus, creating a new one from scratch can be horrifically costly so who'd do it unless there was a really desperate need.

Talking of other-label parts, look in an Aston Martin...

 

Same way they are saving Lincoln? Ford should have no business owning a luxury car brand, as they have no idea on how to manage it.

 

Jaguar needed substantial investment, both to bring out up-to-date product lines and also to modernise production facilities - and it simply couldn't raise the money. If Ford hadn't stepped in, I suspect Jaguar would have gone the way of Rover: passed around various vultures until it was dismembered and the scraps sold to China.

Having access to the FoMoCo parts bin was a big plus - Ford's massive buying power meant that commodity items were much cheaper than for a low-volume manufacturer like Jag. And, let's be honest, a bolt, fastener, relay, whatever, of a particular specification is the same whether it's attached to a Lincoln or a Jag. It's not like luxury carmakers specify hardware made of unobtainium.

When Ford got into trouble and had to sell off the family silver, it was not a brilliant time to be selling anything, and they really had to make the JLR deal attractive. That is why the agreement with Tata included substantial on-going support from Ford, which is still in place today. And of course, Ford is still making money out of supplying components - no reason to cut off a revenue stream.

 

Here is the time line and all the variations used in Land Rover/Lincoln/Jaguar models.

The XF still shares a huge amount with the Lincoln LS/Jaguar S Type. From underneath and the engine compartment the similarities are very obvious.

I just read an article in Hemmings about Ford making an anniversary Mustang for 2015. They will produce 1,964 units and they will be equipped with their 5.0L V8 with 460 HP and 390Lb. Ft torque. It would be interesting to see if the Ford engine team cross talked with the Jaguar engine team when Ford owned Jag.

 

now this is particularly interesting to me....I suppose a fairly cheap way to do some research on this is to buy a Jag OE manifold gasket, and go to the parts store and compare them to 5.0L Ford gaskets. If any match up close enough, maybe headers would fit! Or, for someone like myself, if the flanges were the same I could easily re-fab the headers to fit, if necessary.

 

or not only that, but Im looking into doing a cat delete, even if I left the stock manifolds I could possibly use (re-fabricated, if necessary) some Mustang 5.0L cat delete (test pipes) pipes.

 

I have an exhaust manifold gasket from a 4.2L AJ-33 here.

I had previously checked the measurements against the Windsor 5.0L, Coyote 5.0L, 4.6L Modular and the 3V Ford V8's, no match whatsoever.

The AJ-V8 has oval ports. The Windsor has square ports, the Coyote & the Modular have round ports. The 3V Ford V8 has siamese exhaust ports which are again different.

So i'd be surprised if the AJ133 5.0L would be the same...



I hate to break it to you, but there is no off-the-shelf Ford performance parts that will fit the AJ-V8...
