Tonight I picked up the spare engine parts that came with the Land Rover, but i'm not sure exactly what they, or the current engine in the Landy are.

When I bought the Land Rover, the chap I bought it off had recently built one good engine out of the original engine and a second engine he bought. As far as I understand it, the engine in my Land Rover is built from the original block, crank, manifolds and auxilliaries, and the new engine's head, rods, pistons, and injectors.

Tonight I collected:
Engine Block - c/w diesel pump, canister-type oil filter, alternator, starter motor, crank, flywheel, plus most auxilliaries.
Inlet Manifold - different to my current one.
Exhaust Manifold - again different type.
Cylinder Head - Requires a rebuild, includes injectors.
Pistons & Rods - 3 good, one battered from loose hotspot.

Here's some pictures:

So, what exactly do I have? How can I identify the components?

I suspect the replacement engine parts are from a 2.5TD (19J) whilst the original engine is either a 10J or 12J 2.5NAD. This means that currently i'm running a 2.5NAD with TD pistons, injectors and head. Is there any difference between the NAD & TD in terms of compression ratio, injectors?

Finally, with the parts I have, what more do I need to convert to a TD? Obviously I need a turbo, as I recall it's a Garrett T2 on the 2.5TD's.

Cheers :confused:
 
Wouldn't bother mate, the turbo is more of a turbot than a turbo and you are unlikely to notice the difference, other than it might be a bit less reliable.

Only upgrade really worth doing from a 12J is tdi.

Early 19Js were just 12Js with a turbo, they soon made some mods when they couldn't cope with "all the extra power"!!! (oh the irony!)

If it gets any less reliable it'll never move :p

Don't really need any more power, just need to get the engine running cleaner. Figger'd if I had what should be turbo internals it would be easier than ripping it all apart again to fit NAD bits. If they're the same however there's no point.
 
They made a few changes throughout the life of the 19J to try and make it more reliable, so the later ones are a bit stronger - i got almost a whole 19J sittin in me garden if yer need any bits off of it (few bits missing - like the turbo!) but mostly still there. I think it was reconned just before i bought it (about 8000 miles before i took it out) and it ran OK.
 
The engine is 12J. Those manifolds are of the 2.25 10J.

As far as I know, the only differences between the 12J and the 19J TurDo was the turbo, and a different vacuum system which attached to the crankcase breather and the injection pump which was again slightly different, to allow an injection advance/retard operasted by the turbo. Otherwise, injectors, pistons, block, etc were, as far as i know, the same. And, bung a turbo on your engine and it will probably blow up soon after.

You say you want it to run cleaner, whats up with it currently?

It's got fuelling issues - feels like either the timing is slightly out or the injectors are a bit fooked. Going to swap the original injectors back in (with new washers etc) when I next go round to where the engine is stored and remove them from the original head. Was hoping just to wake the engine up a bit and get it running better. 55-60mph is absolute flat out and it takes an age to get there. Smokes like a bitch too.

If those manifolds are 10J-spec, then the mystery deepens. The manifolds on my Landy are (according to the bloke I bought it off) the originals from the old head. The spare manif's came with the s/hand engine. All the pipework in the Landy looks original and not cocked-about with, so I presume the manifolds are original. Why would a 2.5 12J be fitted with 2.25 10J manifolds though? Unless it came out of a converted Series?

Strange.....
 
Possibly. Some very early 110's had 10J's in, but only a few. And that wouldn't explain the rest of your engine, 'cos that is definitely a 12J block in the piccy. The injection pump is belt driven, whereas on the 10J it was driven off the end of the camshaft.

Perhaps the 10J manifold was used to make it easier to add a snorkel? Can't see why though.

But then why add the 10J exhaust manifold too? :confused:

The engine in my Defender has a screw-on oil filter - this motor has a canister-type filter element. Is that just a variation or has one been buggered about? The service kit I got from MM4x4 contained a screw-on filter and the chap didn't question me as to what type of filter i'd need when I ordered the kit.

By the way Boydy just noticed your location - where abouts in Bangor are you living? I used to live on Farrar Road near the football ground :D
 
Ive just moved into college road, literally over the road from the uni building!

The screw on type filter is what the 12J and 19J have standard, ive never seen one with different. Your one is probably fitted from the 10j, possibly they have the same mounts and someone needed to fit one. Who knows.
 
Hi odenne, do you still have the fuel distribution pump, as I think mine's dead! If you do, how much do you want for it. I can't pay a lot as I'm pretty skint at the moment, due to me trying to get the bloody thing on the road. Cheers, Graham.

Hi Graham, do you mean the injector pump or the lift pump? If the lift pump, i'm afraid Yella had that a while back.
 
I think i still got it but tis on a promise to someone else who might not need it, i'll gladly let you have it for postage cost if he doesn't want it...won't have a chance to look at it till probably sundy though, watch this space...
