Is the 2.5 TD engine any good?

I am after a 90 to use as an off-roader. There are a few nice cheap ones
around but they have the older 2.5TD fitted. I have heard that this engine
is one to avoid as it's very unreliable.

Anyone got any thoughts on this please? How easy would it be to transplant a
200TDi into one in the future if needed?

Thanks in advance.

It's not that bad, better not get the NA one though, or a 200tdi.

I had a TD & it's in Lee's motor now, still running fine.

I thought the 200 TDi was the best one, supposedly bullet-proof??

I have had my 1989 90TD for 10 years and (touch wood!!) it's going well at
130000+ miles

Mind you, I make a point of oil and filter changes every 4 months - this is
important, even thouth I only do about 5000 miles a year

Yup this one has just gone past the 123456 mileage last week :-)

Not all the quick with the caravan on and fully loaded. But plodding along
at 55mph on the motorway is fine seeing as bank hols will mean so is
everyone else!

200 tdi is much better on paper and I understand less relaibility issues.
There are web sites dedicated to the conversion. Steve parker does a kit for
a Disco engine as the turbo/manifold is diffewent than the defender version.

I will be going to 200 tdi if only to explore veggie oil which is more
complicated on a TD.

somewhere I've got a photo of the speedo on my CSW showing 234567, although

For 2 (main) reasons - hey don't want the electronics on the TD5 (won't
survive an EMP attack) and the 200 TDi is no longer produced.

I thought the 300TDi had some sort of chip in it.

What sort of dates are we talking about here?

Mine's an early 1996.

EDC was only on autos, I thought.  Boosted the power a bit.  The EGR is on
all of them but it matters not, it's easily circumvented.

Is that the electronically controlled EGR stuff?  If so it's never

Well, I thought all 300s had EGR.  Maybe that was only the discos.

... it wasn't on the early ones, even autos.

Later releases have an "ecu" but IIRC all it does is manage the
exhaust gasses.  My 300TDi is gadget-free.  From the wiring diagram I
have for a Defender, the ECU apparently hides under the driver's
seat.  I don't recall which versions of 300TDi defender have them but
I know mine isn't one.

Military Machines International April 2008 edition has an article on
modern technology in military vehicles.  They don't mind electronics
too much but can only go as far as euro 3 spec on the engine, that
seems to be where they're digging their heels in as the others have
all sorts of weird sh.t to keep pandas in the mood.

They've also standardised on independent suspension on small to medium
sized vehicles because they reckon it's got a 2-3 fold speed advantage
over rough ground than beam axles, but on heavy load carriers they
prefer beams and leaf springs as it's the most reliable and the load
carriers don't need speed (so no independent suspension) or much
off-road capability (so leafs are OK).  There's currently one load
carrier with independent suspension in production, from oshkosh I
think, the rest are beams.  I might write in though because that last
bit is according to the article, but tatra trucks have independent
suspension, I don't know if the writer regards them as beams or
independent..  I don't know if Tatra are in the military market much
these days though.

Also some work has been done on using hybrids but so far, and not for
a very long time into the future, they're regarded as totally
unsuitable due to reliability issues.  You see companies like Oshkosh
displaying hybrid models on their web pages but they're not apparently
being bought, or possibly even being sold.  It looks "good" for those
who think such things are more important than not getting killed.

I must be biased as I've got one on ebay #280208594138  :-), but, coming
back to your question, the 2.5 TD is nowhere near as good as a 200 or 300Tdi
but it's a big improvement on an N/A.

I'd agree about the Tdi, but the n/a isn't much slower than the TD and it's
bulletproof - the Army used them for years and kept coming back for more.

All I can say is the TD you compared it with must have been utterly
knackered.  :-)

Heh.....  It may have been bulletproof but I would rather have one that
would run than have to use it as a shield.

Yeah nige .......How many engines.

When the TD first came out  they were changing them weekly under
warranty.

They suffer badly from cracked pistons and heads.

They pressurise the crank case pushing oil into the air filter, many
have had the breather system changed to stop this from happening.

If I buy a 90 or 110 in with a TD engine in, it gets scrapped or
re-engined. As I can't warranty a TD.

That said even though the are technically knackered they keep going for
ages with all these faults.

Most will have developed the symptoms by 50,000 miles.

A 200 is much more cost effective in the long run.

Indeed, the 2.5 D was never redesigned to cope with the heat loadings from
the turbo, even though it only blows at 6-7psi.

An intercooler, proper setting up, and the PCV mod cures them, but having
said that, you might as well fit a 200TDi which is a far better engine.

In addition I would venture that until the 1.8 freelander that the 2.5TD
was the worse engine that Landrover ever fitted . . . . . . . . .  oh
wait a min..... no the VM unit fitted to the RRC was just as shite.

Just as the slightly redesigned VM 2.5 that they fitted to the Cherokee was
attrociously awful...!

Mate of mine has got one, and for some reason no-one will buy it from

Actually, it's not as bad as all that - however, it suffered from inadequate
attention to re-torqueing the head bolts, AIUI, leading to premature gasket
failure.

VM are actually quite a respected company in diesel engine circles.  The LDV
Maxus van has a VM, though I doubt it's the same one as the RRs.

My mates Cherokee hasn't had any head problems yet, and it's on 107k
miles, but it's definately the poor relation in comparison to the 4.0
petrol one, and if it's driven in such a way as to make progress it
doesn't seem much better on fuel.

VM do some pretty good engines, but the one in the Cherokee seems to be
an exception. The VM lump in the Rover SD1 seemed to go ok, if memory
serves me right.

LOL, its about as far away from the original 4x heads effort as apple
crumble is from sherry trifle.

In 2.8 guise now in the Maxus, its not too bad. Long term reliability both
mechanically and electronically (the CR wiring looms aren't upto Bosch or
Delphi standards) are as yet un-known...

I had one, did the head gaskets twice and replaced the pistons and bearings
... however apart from that it's a better spec engine than the 200 tdi on
paper. I've never compared like with like mind. Though I'd have avoided it
through reputation and yes the head gaskets were a pita otherwise it was a
sound engine. There are many more VM's out there than there will ever be 200
tdi's ... they also have them in Granda , Omega, Rover, Jeep, (came to my
rescue when landrover didn't have parts in Jeep did!). The basic engines
main application is in a marine engine so there will be shed loads of boats
with them fitted too.... awaits anchor gag :-)

I seem quite fond and partial to all these lumps no one wants :-)
Remember - A Landrover is not just for Christmas!

If the 2.5 TD in the 110 had the power of the 2.5 VM then that would be a
nice engine. If reliability was a primary concern then we'd all be running
Land cruisers and the green oval would have been dead a long time ago.
