So, in my ongoing quest to deal with the 2.5D lump under the bonnet of my 110, I've been offered (and promptly bought!) a 2.5D with a whole 45,000 miles on it.

I am pleased - thought I'd end up having to buy some shagged-out lump and rebuild. This suits me... :)

However, as the engine is out of the truck and going to be installed, it occurs to me that a refresh of certain components is likely in order. First item that occurred to me was valve seals - from previous history I'm aware that these don;t hold up well and you get blue smoke on overrun and other issues. The injectors are going to come out and get cleaned/reset (I have the equipment to do this).

Valve adjustment, obviously, if I'm replacing the seals.

Likely do the timing belt as well if the bugger's on the shop floor anyway.

So, what else should I do?

If it was me, I'd probably sell it and put the money towards a 200Tdi. Easy swap and so much better.
 
check the main shells to make sure it really is 45k.

change rear crank if any sign of leakage.

do belt and any iffy gaskets

check core plugs

I like the 2.5d engine...

Really?

OK I'm not saying they are bad. In the absence of anything better they are very ok. But how can anyone like 67hp vs 111-130hp, low torque output vs 180-220ft lb or torque? Low 20's mpg vs mid to high 20's mpg. Very sluggish performance vs something capable to keep up with modern traffic?
 
When you start putting a 111-130 bhp engine in a system that is probably old, and a bit knackered its not just the engine you have to then worry about...its everything that is connected to it :)
 
If youre taking head off to do valve seals, will be worth lapping in the valves and checking the precombustion cambers for cracking or coming loose. Also rear crank seal behind flywheel
 
They are good uncomplicated old beasts. Gasket kits are pretty cheap so get what you can whilst it's out.

I think a decent 2.5 suits the braking and steering limitations of the standard 80s vehicle. 30mpg is easy enough to get too. The simplicity of the engine is a big appeal to many owners. Of course it struggles to keep up with modern traffic, so does just about everything built in the 80s. It's faster than my first car - a 2CV!
 
Steering and brakes on an 80's Ninety are the same as those on 2015 models. Rear discs accepted. But good drums work almost as well. Same steering and brakes as you'll find on a Disco 1 or RRC too.

I disagree. I'm having a spot of bother with my 2.5 at the moment but the trouble I've seen with 200tdi engines has put me off. I'm also happy with the 26mpg I get and why do I want to go any faster?

Not a big issue for off road and local use. And everything is much cheaper for the older engines, couple of quid for a fuel filter, forty quid injector service. And all British made, no Bosch under the bonnet! :)

And why do I care about keeping up? I pay my road tax! Let them sit back there in a cloud of fumes! :D

If I need road performance for towing, I take my v8 disco. :)

What a complete load of utter bollox.

Why is it bollox......if i wanted to put a ****ty 200tdi in my 110, then i would have purchased a 200tdi in the first place.
And if you put a more powerful engine in system that has, for decades, had lower horsepower then you are going to get problems. You dont just replace the 2.5 n/a, you should get shot of the lt77 gearbox as well....unless your a bit of bodger :)
 
This could run on and on, however there's not much point coming on the 2.5NA forum and saying it's a bad engine. Many people like the simplicity and aren't worried about the low power output. It was certainly enough for a recent 700 mile trip to SW Ireland, where most of the roads limit any vehicle to 30mph.
 
And to wrap it up...

The "new" 2.5D is in the engine compartment and propelled me to work this morning at a steady 60-65 MPH with no strain.

I ended up replacing a piston (cracked..found that out on startup...lying sack of clods seller...) and the head/sump gaskets, rear and front mains, and the timing belt. Injectors got swapped as the originals would not come apart to be serviced - will deal with them later.

Runs like a charm, does everything I want it to do, and is a net win any way you look at it.

Well that's bollox in itself as the LT-77 was standard equipment with the 200Tdi. The LT-77 has also been used in many applications behind the Rover V8.

All the driveline components of any Ninety/One Ten are fully capable of being used with a 200Tdi.
