........Or anyone else who may have deep knowledge of the history of Jaguars X-Type 3.0 V6 engines. What I am looking for is where are the blocks and heads cast, where are they final assembled, that type of thing. Even a link to a Webpage with some history of the Jag AJ-V6 3.0 liter would be cool. Thank You.

The jaguar engine is a modified Ford Duratec, see details below
6 Cylinder

All three V6 Duratecs are evolutions of the same design. It is a modern aluminum DOHC V6 with a 60° bank angle. The primary engineering input came from Porsche, who were developing a similar V6 before selling the engineering to Ford, and Cosworth, who helped with cylinder head manufacturing.

The Jaguar AJ-V6 engine is similar but adds variable valve timing. Mazda's AJ version also has this feature.

Duratec 25

The Duratec 25 is a 2.5 L (2544cc) 60° V6 and was introduced in 1994. It was developed for the Ford Mondeo and used in the Ford Contour, Jaguar X-Type, and others. Bore is 82.4 mm and stroke is 79.5 mm.

The Duratec 25 was on the Ward's 10 Best Engines list for 1995 and 1996, and the SVT version made the list for 1998.

Duratec 25 SVT

An SVT version produced 195 hp (145 kW) and 165 ft.lbf (224 Nm). It included a larger throttle body from the Duratec 30, a new cone-shaped air filter, and extrude honing on the intake manifold. A lighter flywheel and low-restriction exhaust complete the picture. The SVT engine was used in the 1998 Ford Contour SVT.

Duratec VE

The 2.5 L, 170 hp V6 used in Ford Mondeo is called Duratec VE.

Mazda AJ

Mazda used the Duratec 25 block and camshaft in their 2000 MPV. However, they reduced the size from 2.54 L to 2.49 L to keep under a 2.5 L tax cap in Japan. This was accomplished with a slightly-shorter stroke. The engine produced 170 hp at 6250 RPM and 165 ft.lbf (224 Nm) of torque. It was replaced in 2002 with the larger 3.0 L Duratec 30-based Mazda AJ.

Duratec 30

Ford's standard DOHC V6 is known as the Duratec 30 or Mazda AJ. It has 3.0 L (2967 cc) of displacement and produces between 200 and 240 horsepower (150 and 180 kW). The same engine is used by the Jaguar S-Type, Lincoln LS, Mazda MPV, Mazda6, Mercury Mystique, and many other Ford vehicles. It is essentially a bored-out (to 88.9 mm) Duratec 25 and is built in Ford's Cleveland, OH #2 plant. A slightly modified version for the Ford Five Hundred entered production at the Cleveland, OH #1 plant in 2004.

It has an aluminum engine block and aluminum DOHC cylinder heads. The cylinders are lined with cast iron. It uses SFI fuel injection, has 4 valves per cylinder and features fracture-split forged powder metal connecting rods and an assembled cast aluminum intake manifold.

The Lincoln LS version has bucket tappets and produces 232 hp (173 kW) at 6750 RPM with 220 ft.lbf (298 Nm) of torque at 4500 RPM.

The Taurus/Sable/Escape version uses roller followers instead and produces 201 hp (150 kW) at 5900 RPM with 207 ft.lbf (281 Nm) of torque at 4400 RPM.

Applications:

208 hp
1994-2005 Ford Taurus/Mercury Sable
2001-2005 Ford Escape/Mazda Tribute
232 hp
2000-2005 Lincoln LS
Jaguar AJ30
Jaguar S-type
2005 Ford Five Hundred, Mercury Montego and Ford Freestyle

Mazda AJ

Mazda's AJ version adds variable valve timing, as does Jaguar's AJ30. It displaces 2886 cc with an 89 mm bore and 79.5 mm stroke. Output (on the MPV) is 200 hp at 6200 RPM with 200 ft.lbf (271 Nm) of torque at 3000 RPM.

Mazda AJ

2002-2004 Mazda MPV, 200 hp
2005 Mazda 6

Duratec ST

The 3.0 L, 226 hp V6 used in the Mondeo ST220 is called Duratec ST.

Duratec SE

The 3.0 L, 204 hp V6 in the Mondeo Titanium is called Duratec SE.

Duratec 35

The Duratec 35 (code-name Cyclone) is a new 3.5 liter V6 that will appear in 2005. It is an all-aluminum engine based on the Duratec 30, and adds variable valve timing, a feature already found on the Jaguar AJ30 and Mazda AJ versions of the 3.0. Its displacement can be increased to 3.8 liters, meaning a Duratec 38 could come soon after.

The aluminum block is made by Teksid in Alabama, while the heads come from Newmak in Mexico, and the crankshaft comes from Bharat Forge of India. The engine will be assembled in Lima, Ohio.

Thank you for the information dominicf.

I'm starting to get confused as some Websites are saying the AJ-V6 is an S-Type engine and some say it's an X-Type engine. I want to focus on the 3.0 liter X-Types engine family, is it actually information on the AJ30 that I seek?

Trooper2,
The S and X 3.0 use the same duractec 25 2.5 bored out to 3.0. The S gets extra power 240 over 231 for the X because the S engine is fitted longways and the exhaust manifold doesn't have to go through 90 degrees as the sideways mounted X engine.

I'm pretty sure the block is cast in Windsor, Ontario, I'm not sure about the heads, but everything is machined and assembled in Ford's Cleveland Engine Plant, in Brook Park, Ohio.

The engine has a lot of similarities to the Ford engines, but differs wildly in that the heads are DAMB - Direct Acting Mechanical Buckets, versus RFF - Roller Finger Follower as used in the Fords. This is in line with what Jaguar put in their V8.

The Jaguar and Lincoln engines were built on the same line in Cleveland - the DAMB line, and the Ford and Mazda engines were built on the RFF line. The Jag engines have all had VVT, the Lincolns as of 2003 MY had VVT, prior to that they had fixed valve timing.

I don't know of a website the public or even dealers can access to get further information - sorry.

Thank you very much gentlemen..

I thought that I may have seen a video at Jaguar school that the heads were a complete re-design from Fords original and that IIRC it was done in-house at Jaguar or perhaps Cosworth in England, does that ring any bells for anyone?

The heads were a complete redesign and the single cylinder work was done at Jaguar Whitley.

Sorry I didn't see this post until now.
I can't rememeber the exact codes for the engine now. The AJ30 is the V8 as used in the Lincoln.
AJ67 MAY Be the traverse X type designation.
Let me email my contact at Jag!
I did alot of the design/concept work on the inlet manifold, cams, ports and combustion chamber, exhausting of both the V6 and V8, obviously in league with CAD design and the single cylinder combustion team.
