Ford ranger engine in an LR3?

Hi All, Newbie here.

So here's the scoop.

We bought a 2006 4.0 LR3 about a month ago. Spent money on new tires (Copper discoverer H/T Plus. Very good) and bought a whole set of controls arms front and back (sitting in the garden, waiting to go on)

Then the engine blew! In the middle of absolutely nowhere in BC Canada... at midnight... in the bear infested bit... on a long weekend.

After a $2000 towing bill to get it 14 hours home, it turns out the engine is toast. Limping it 160km to the nearest one horse town means the engine is full of the camchain cassette filings and done for.

Landrover Canada wants $11,500 for a new engine... plus tax... plus shipping FROM THE UK! :-)
Ford wants $4400 for a new Ranger 4.0 engine

I can't find a second hand engine in Canada.

I can however, find a very lightly used 2007 Ford ranger 4.0 that is technically the same engine (except lower compression and different timing, the differences I've found so far) for $650. meaning the computer is going to give a big "Nope" if I put it in.
... saving a gazzillion dollars!

So, to the help part. :-) I need a Guru. someone that can tell me what the differenced are between a Ford ranger 2007 4.0 V6 and an 2006 LR3 so we can canibalise the different buys into the new engine.

Has anyone ever attempted this? Did anyone find software issues and fixes? If its not possible, where do I find an engine in Canada nd any other useful information anyone has.

*Someone, *somewhere* must have the information of the differences between engine part code 300AABB (or 300AABC) with a ford part number of 6006 or 6007 and a Ranger engine part number 6006AARW

So, over to you guys :-)...

Majority of LR3 buyers go for the 4.4 V8 its a known reliable engine that can move the 5K pound LR3 and do over 300K with out issues. The V6 LR3 was a lower end model that Ford pushed for a short period. That said, those V6 engines are known for its issues. It's possible that you can replace it with a used V8 4.4 instead of the 4.0 V6. or sell the current in parts and get a proper V8 LR3.

That V6 engine is a "Ford Cologne" engine fitted to many US and UK Ford vehicles so should not have too much of a problem if you get one that has the same outputs (Kw and Torque) as the LR3
I would use the block and add all LR ancillaries

Just a quick update to say that it finally got sorted out. I had to import a used engine from the US as Land Rover have discontinued the LR3 Engine. Had it checked and the camchain tensioners were already snapped at 90,000km so had them replaced and the engine fitted the the LR3

Total cost $12,000

... for a car we bought 3 weeks before for $10,000

We'll own this car until it dies now.. and I'll never buy another Land Rover as long as I live. ;-)

Thanks for the update.
Maybe I missed something or maybe I didn't
But
When you bought this 11 /12 year old vehicle
- did you have it inspected by a professional who knows Land Rovers?
- did you ensure that all previous maintenance and preventative maintenance had been performed and performed correctly.
- did you buy it expecting a low cost , low maintenance vehicle?

Time will tell whether you love it , sounds like right now not so much

Sounds like the used motor you sourced was likely poorly maintained as well (darn yuppie soccer moms) good for you in having it checked out before the install.

Sorry to hear about your Issues. Wish I was on this forum sooner to help you trouble shoot your LR3.
-From my research I believe the long block is the same engine in an LR3 as a ford ranger and explorer 4x4. It’s has to be a 4x4 v6 from a ford because it needs a balance shaft installed.
- Engine compression ration in the Land Rover Data shows 9.75:1 + or - .5 for the V6. Some literature even says 9.7:1.
- Ford lists all 4.0 sohc at 9.7:1
- Now as for the power output. Ford lists all the horse powers between 205-210hp on regular 87. Land Rover clams 216 hp on premium. Also the lr3 has dual factory exhaust which I believe is the exact same as the v8 as the catalyst are the same from after market part number cross examination. The lr3 v6 basically also has shorty, dual wall, stainless steel headers from the factory which most likely flow way better than the cast iron manifolds Ford installed on the 4.0. This all can explain the extra 6 hp easily along with a premium fuel tune.

- To explain the extra torque output of the LR3. I must say this is the one thing this engine does well. Basically all Ford 4.0 sohc engines are rated at 240 ft/lbs except those with either a active intake manifold, like the lr3 and 1997-98 explorer, or long runner intake, like the 2002-2009 explorer. With the better intake manifolds the Ford Explorer pumps out 254ft/[email protected] 3500 RPM. The lr3 with its beautifully designed aluminum active intake manifold puts out 269ft/lbs @ 3000 RPM. With one ignition coil per spark plug and premium fuel tune,which can advance the spark sooner, I think this accounts for the better torque output at lower RPM.

- I have repaired my 2008 lr3 a few time. Most parts fitted to the v6 are stamped Ford Mo Co. I have even used the map sensor off a junk yard 2006 Explorer sports track to fix mine. Same part number and all.
- I don’t think Land Rover had the budget to reengineer the 4.0 SOHC from Ford. If they had I’m sure it would be pushing out bigger numbers. The 4.0 is limited by its cylinder head air flow because it’s only 2 V per cylinder, this explains the great torque but how it runs out of breath by 4500 RPM. Land Rover would have to spend a great deal to improve the 4.0 sohc over its explorer roots and since this was to be a lower range engine I think they changed as much out side the long block as they could and strapped it to the sweet ZF 6 speed and called it a day.
- I plan to use a used or rebuilt ford engine when mine goes. I will compare all internal part numbers on the cams, heads and pistons but I’m 95% sure everything will be identical from all the research I have done.


- The timing components I believe are failing on these engines, especially on the LR3, because of long oil change intervals. The chain guides are not the best, especially on the passenger side, but if you keep up on your oil changes and use a great filter these engines will last a long time.
- My oil service reminds me every 12,000 km on my LR3 which I believe leads to the tentioners plugging up and then comes chain rattle on cold starts. Eventually causing timing chain guide failure. I only go 5000km on synthetic with an FL80 motorcraft filter in order to get the best life out of my 4.0 sohc.

I hope This research I have come across can help those with future problems.

Who cares if it's 11/12 years old? The fact the engine blew up on him after ONLY being 11/12 years old just verify's it's a POS. Was he supposed to know what he was getting into. What kind of engine blows at 11/12 years old? It's garbage. My friend had a 69 Mustang. Same engine. Still drove accordingly. Engines have been around for 100+ years. It should be a standard item for all humans to produce - with no problems or defects.

How is Land Rover considered a luxury brand when the cars are this unreliable? I would be furious. He should send the towing bill to LR Canada take the refusal to pay letter he will receive - pay a publisher to spam it all online. Get hundreds of thousands of views and lost sales. That's what LR CA deserves.

I doesn’t matter if it’s a Toyota or Land Rover if maintenance isn’t done a vehicle will fail. That’s the point I believe is being made. The more gadgets and computers any machine has the more chances for Problems. I have had a few problems with my LR3 but I don’t consider bad engineering. I personally think the LR3 is reasonably reliable considering it’s capabilities.
I have driven from Canada to the Southern California Desert with my Entire family, then 4 wheeled through Joshua Tree national park in 100 F and driven back home to Canada all without one problem. My LR3 has taken my family to places they would never see in a minivan. A little extra maintenance is okay by me.

Land Rovers don't seem to require a little extra maintenance. They seem to require full time extra maintenance to the point of obsession where I would never own this car if I needed it as a daily driver AKA dependable normal car.

If you change the oil on a Toyota and Land Rover every 15,000 miles there will be a pronounced effect on the Land Rover vs. the Toyota when there should not be. That is what makes LR junk.

I am saying this because I am suspecting my LR engine is going to blow up soon. At only 120k miles....I've pampered this money pit with bathtubs of Benjamin Franklin's. I should be getting 500k miles out of this thing. Not 120k miles.

Hi all, am new here also and in the same situation as the OP, just picking up my LR3 4.0 (2007) with dead engine this weekend, but am planning on installing a 4x4 Ford 4.0 SOHC as it's replacement. At least as much of the Ford that will play nice with the Land Rover ECU and accessories. The engine had a timing chain incident where at highway speed the rear chain decided to slip or break, consequently causing a catastrophic internal collision of rapidly moving parts. A lot of research on paper indicates that this is optimistic, but I'll find out when I start disassembly on Monday or Tuesday next week...

Edited to add photo, retrieved the dead machine on Saturday May 18...
