Ok, this question is for all the master LR mechanics out there... Can you put a 2003 Discovery motor in a 2000? Are there any major changes between the two years? Computer? Secondary Air? etc... Anything I should watch out for? It is my understanding that if the serial # on my motor begins with a 56D (which it does) then it has Secondary Air Intake...is this correct? Thanks for the help.

Bueller? Bueller? 2003 has the 4.6, whereas the 2000 is a 4.0. Might need to change the ECU settings to get it to run better. (It should run even if you just threw it in there, but there'd be consequences to not making sure that it's running optimally). -L | ||

I am replacing the motor in my 2000 and I found a better deal on a 4.9 out of a 2003. If it is not too much of a hassle I would put it in, but I am worried about any differences that might screw up an otherwise smooth process of putting the same motor back in. I also need to check into the availability of the ECU for the 2003. Has anyone put a 2003 ECU in a 2000 Disco? I am afraid I've stumbled into uncharted waters. Mike | ||

Mike, This is a topic that has been covered a couple of times over the past few months. The threads have been centred around replacing 4.0 with 4.6, and was reflected in the threads subject. Victor | ||

That's "4.6" you meant right? Not a "4.9". And yea there's lots of discussion of this idea and some on this board have already done it. It'd be sweet though if it was a 4.9. Vroom, vroom! | ||
| Mike (Shinerguy23) New Member Username: Shinerguy23 Post Number: 13 Registered: 01-2004 |
Yes, 4.6, sorry. | ||

I'd like to know too, I've got a new short block going in my D2 next week...is it possible to go with a 4.6? | ||
| Mike (Shinerguy23) New Member Username: Shinerguy23 Post Number: 14 Registered: 01-2004 |
Sounds like you are in the same boat as me Steve. Why are you replacing yours? The sleeve slipped in cylinder 5 in my 2000 Disco with 70k on it. Very disappointing I must say. I was really hoping that all the things people said about these engines weren't true. I found a good deal on a 4.6 long block close to me. I was hoping to get a good thread going, but I've been directed to old threads instead. | ||

My block is in the same boat...mine is a 99 and just turned over 70K...cylinder #5 sleeve as well...mine is under an extended warranty, so I will probably have to go with a new 4.0 short block...but a 4.6 would be nice! I'm on my 3rd transmission too...needless to say, I don't venture too far from populated areas and cell phone coverage!! | ||
| Mike (Shinerguy23) New Member Username: Shinerguy23 Post Number: 15 Registered: 01-2004 |
What a coincidence?! OR IS IT?! I am convinced that there is some sort of factory defect with a batch of engines with this same problem. I have talked to a lot of people who have told me that sleeves slipping in the 4.0s is a lot more common then anyone likes to admit. Unfortunately mine is not under an extended warrenty so I am left out in the cold. We should get together and push our kindred rovers off a cliff together and collect the insurance money! HA! Too bad you are in AZ, we could have an engine swap party! | ||

It really is too bad, because these are such cool vehicles in every other way...I would be scared to drive one without the security of a warranty...the odds of something bad happening are just too high. Maybe Ford will run a tighter ship. | ||
| Walter Dent (Walter) Member Username: Walter Post Number: 41 Registered: 11-2003 |
Ford run a tighter ship then BMW? I doubt it. | ||
| Steve Turpin (Steveturpin) New Member Username: Steveturpin Post Number: 8 Registered: 01-2004 |
BMW didn't stick with the program long enough...might of been a wise choice for them though. Besides, Ford hasn't done too bad with Jaguar...a company that had a very similar reputation to LR. | ||

Damn... all these D2s biting the dust too early. You guys might have a legitimate beef with LRNA if you guys join together. Good luck guys! Glenn | ||

Mike Call and e-mail LRNA about the no.5 liner slip at 70K. I read elsewhere that a bunch of 4.0 blocks were also cast to modern British "standards". Even replacement 4.0 blocks are showing up meeting modern British "standards". WTF is the matter with those guys? Did they hire nothing but wankers from management down to the sweepers? Are they still pissed 'cuz were no longer a coloney? Hey Rover/Ford - If you quite shipping crap, we won't have anything to bitch about...Oh, wait... upgrade your friggin' drive train while your at it. How 'bout a decent 5-speed, you friggin' humps. I don't care if you copy an NV-4500 or whatever. And take a crack at axels and CV joints while your at it. Jesus. | ||
| Mike (Shinerguy23) New Member Username: Shinerguy23 Post Number: 16 Registered: 01-2004 |
We really should band together and make them make this right! I talked to a Rover shop owner today who told me he sees it all the time! Anyone have any good contacts at LRNA that we could shakedown about this? | ||

I don't think it's just the Friday afternoon trucks, as everyone would like to believe. | ||
| bluesman (Hywy61) Member Username: Hywy61 Post Number: 86 Registered: 02-2003 |
Let us know what you guys find out. I have a 2000 DII with 52K - now i have yet something else to worry about. | ||
| bluesman (Hywy61) Member Username: Hywy61 Post Number: 87 Registered: 02-2003 |
i just thought of another question. Have any of you guys had a valve job on these engines? I am wondering if a valve job had been done would the engine still have the same problem? I had a valve job on mine and not exactly sure what is replace there. thanks. Novice mechanic here...trying to learn. | ||
| Steve Turpin (Steveturpin) New Member Username: Steveturpin Post Number: 12 Registered: 01-2004 |
I had a valve job on mine, but I don't think that really matters, as this is a defect in the engine blocks. | ||
| bluesman (Hywy61) Member Username: Hywy61 Post Number: 88 Registered: 02-2003 |
thanks - before i had a valve job i had a few misfires on cylinder 5. this was about 7k ago. Of course now i am not under warranty. Let me know what you find out as i might have to go down the same road. | ||
| Steve Turpin (Steveturpin) New Member Username: Steveturpin Post Number: 13 Registered: 01-2004 |
If it comes back, you'll know you have a problem...don't let them just replace the plug and wire, as it will just come back again in 6 months. You might consider getting a warranty if you plan on keeping the truck... | ||

I spoke with a guy that runs a rover shop here in Dallas and he said that he sees cylinder sleeves slipping all the time. His theory, which he has developed with his contacts across the pond at LR is this. An engine that is already running very hot under normal operating conditions is put under further stress by US emissions standards that force the engine to run very lean. Who knows. This past weekend I finally got around to pulling my engine and purchasing a new short block from LR(jobber). Word to the wise...you better have some small hands (which I don't) and good tools (which I do) to remove the top 4 trans bolts from the bell housing. What a PITA that was!! I am in the process now of building up the new short block which I plan on dropping in sometime in the coming week/weekend. If this shortblock swap doesn't resolve the issue I am setting it on fire and pushing it over a cliff. >;) | ||
| Steve Turpin (Steveturpin) New Member Username: Steveturpin Post Number: 15 Registered: 01-2004 |
I'm in the same boat, although my extended warranty is covering it...same problem, same cylinder. 3 transmissions and 2 motors in 70K, and that doesn't even cover the small stuff like valve jobs and head gaskets...not bad!! If this engine goes down, I'll meet you on the cliff and we can push them over together and tip back a beer! | ||

"...you better have some small hands (which I don't) and good tools (which I do) to remove the top 4 trans bolts from the bell housing. What a PITA that was!!" Or some long extentions with wobble or u-joints in them. Ron | ||

I've always wanted a Discovery (well, D90 but didn't want to pay 30K+ for a 96 or 97) and finally got an '03 SE in Sept of '02. You guys are not instilling any confidence in me about the quality of it (although I haven't had any significant problems yet). Guess when my warranty runs out I'll get another one. |
