I want a shop manual for a 94 disco, sticker says 05/94 but I'm not sure if this is the production date. Are there two different engines for that year? If so, are there two separate manuals or does the same manual cover them both? Any help appreciated. Dean | ||

The 3.9 IN 94-95 are the same pretty much except for some components of the heater system. | ||

Ron B was saying there is a difference in the earlier engines of 94, and that they were more difficult to work on the heads or something, which is why I was asking. Maybe he'll chime in here at some point. Also Will, I hear from Peter B. that you might have some of these engines occasionally - is this right? I've got to look at the engine and work out whats up with it, but if I need a recon short block (or heads) do you have anything available? | ||

I do have new blocks. The 94 has those heater "bypass" hoses and a valve that go over the passenger side of the valve covers but that is the only difference I have noticed. I have both a 94-95. I havent had to break the 94 down yet though so there may be other issues I do not know of. | ||

Engines built prior to about march 94 are different in many ways. like oil-pump, block, drive belts are V belts instead of serpentine, Extra bolts in the head. | ||

Thats correct but we are talking about North American Disco's here. The Serpentine Belt was on all 94 Discos. The RRC switched over in 95. | ||

nope Shaun is right, there are v-belt 94's running around, I know of 1 on a dealer lot near me and have seen a couple others. | ||

I have a question regarding the 3.9 engine that maybe someone can help me out with. I am converting from an old engine to a 94 3.9 off of a disco. As I was swapping the disributor and I noticed that there was no driving shaft for the oil pump on the 94 3.9. What drives the oil pump in this engine? My old engine has a shaft that comes up and goes into the distributor at the lower end, roughly about an inch in depth. | ||

You have a serpentine engine ie it uses a serpentine belt, these engines have a differnt oil pump to the 3.5 and early 3.9. You can fit our old timing cover and early pump and dizzy. | ||

Dean, You are over the engine number break almost certainly. So don't worry. It is not a huge deal, just the early ones are a little different. The manuals are the same and cover pretty much all rover V8s. Ron | ||

Orlando, The distributor runs off of the cam and the oil pump runs off of the crank (pump in timing cover housing). As far as V-belt versus serp belts on the initial NAS Discos, I have a '94 with a date stamp of 03/94 and she has a serp belt... the V-belts have to be some Canadian imports or something .But hey, a "GENUINE" NAS V-belt Disco may be some sort of collectors item that will fetch huge $$$ from a financially irresponsible Disco enthusiast... | ||

Ok thanks all. Its got the serp belt so I assume its the later version. Engine has a broken connecting rod, which punctured a hole in the lower side of the block. If this is the only thing wrong with it I'll see if I can patch it up with a plate. Anyone know where in NJ to send it or the heads to get them reconditioned if I have to? | ||

Orlando, Ron is correct on all engines with serp belts the oil pump is inside the timing cover and is driven off the crank. Unlike your early engine, as I said before you can use the early cover as long as you use all the bits like the dizzy from the early motor if you realy want to. | ||

Dean, You need a new block you can't fix that. And even if you could the number of other bad things that could happen or cause a rod to break is so high that it owuld be retarded to reuse the block. You can have a new 4.0 to your door for $1200, bolts gaskets etc and you will be in the 1500 range. Used 3.9, you could probably find cheap but it is hit and miss with used. Start taking pictures and take out the engine as one piece. Ron | ||

Ron - 1200 for a new short or long block? PeterB thinks it could be a leaking injector that basically filled the cylinger with gasoline and hydrolocked it when it started. It pisses gas all over the place when I crank it over. That price for a new engine - where is that from? Here's a pic! Dean  | ||

Ron - with that new block would I need a new ECU? | ||

With a 4.0 you won't need a new ECU. We sell and install 4.0s to old trucks all the time. Usually deliver the blocks for around $1000 + or -. | ||

Mike, ok thanks. Is that price with the heads? | ||
| Mike M (Rangeroverhp) Senior Member Username: Rangeroverhp Post Number: 255 Registered: 09-2003 |
That's a short block. Are your heads damaged? There are options. Contact me off line. | ||
| Dean Brown (Deanbrown3d) Senior Member Username: Deanbrown3d Post Number: 1565 Registered: 02-2002 |
That was quick! I'll shoot you an email tomorrow. I haven't checked the heads yet, I'm waiting for the snow to melt now! May not even need a block, I'm just looking at what the options are. |
