Thread: Defender engines

We had a D1 with a 300Tdi which was still going well at 340,000 km. Just need regular servicing and timing belts and they go forever, that's why the British Army chose them.
Our Puma is at 160,000 and is fine. These things have been flogged to death and neglected in Transit vans all over the world.
They are both tough reliable engines.
The 6 speed gearbox works well with the Puma, but a 5 speed plus 300Tdi combo is also good, although not a rocketship.

Are u handy with a spanner? This will save u heaps of $$ over the long run...

I have both a Tdi300 and the Puma 110 Wagon and they are quite different in performance and interior as well. I love them both and use both as my daily driver but I work shift work and therefore do not drive in daily peak hour driving. I think in any manual vehicle this would become a PITA over time...

Tdi300: No electronics / Simple / parts fairly cheap / not so sensitive on fuel quality / pretty good on fuel / slow but not annoying slow as there is some mods that people do / very basic inside and out / A/C not that good. I love driving it as I get to see my surroundings more so...

Puma: Mine is remapped and it goes really well and it makes for a great touring vehicle and I also drive it to work sometimes just to give it a run. It has a better interior and dash and A/C but has a few shortcomings that by now most have probably been fixed. It's obviously a lot more fuel sensitive and costly should anything happen in this area...

Thanks Robmacca for the feedback

Luck to have 2x, Im struggling to buy one
As far as 'handy with a spanner' I know what one is, but I'm not mechanically minded.
I have a good mechanic, but not a good bank balance so I had better learn

My dream would be able to buy something simple that I can learn bits and pieces on the fly.

I'm leaning towards a TD5 (for some reason) I guess I am thinking on road speed - a Puma may be a little out of my price range.

My fear on the 300tdi would be the top speed on the highway - even my first TD5 wasn't that great - used to top out at around 100khp
I've heard to look for a TD5 after 2001 - I can't recall why - from memory it was to do with probs with the engine mounts and a few bugs - any ideas?

The 300tdi - I fear may be too slow - especially for Sydney freeway driving - although potentially I could research some mods to improve that.

Thanks again
Steve

Perentie?

I'm not real up-to-date on TD5 but what I know:
Early ones had plastic dowels in the head which melted if the head got hot - All should be fixed/replaced by now I would have thought
After 2002/2003 model Td5's switched from a Salisbury rear diff to a rover rear diff
Oil seeping up the injector wiring harness
Injectors are costly to replace (same goes for the Puma)
I think there was an issue with the bolt for the oil pump (?? not sure) but assume these issues also would be fixed
Poor A/C like the Tdi300
Electrical issues ?? (unsure what)
Remapping can only be done to a certain version (unsure if its before 2002 or after) I may have got this wrong though but I remember reading it somewhere..

My 300Tdi is fairly standard (unmodified engine wise) but to be fair, not used that often nowadays. There was a period when it was my daily driver.
I've never had a problem keeping up with traffic on the freeway, maybe a bit slower getting to top speed. If I unloaded the storage system and gear in the back it would probably be a bit faster getting there.

One of my boys has a 300Tdi Disco and he's constantly playing with the injector pump settings. Drives it like it's stolen, pushes out quite a bit of black smoke on acceleration, I'll have to find out his top speed. I did follow him on the freeway a while back, he was towing a car on a trailer and was sitting on 100kph.

Can't comment on TD5 as I've never owned one but I get the impression that they have better performance and a whole different range of problems compared to the 300Tdi.

i don't get the hate on the performance of 300tdi powered vehicles

they perform fine if you take the time to drive to their abilities...

mine does 120+kph pulling a van when needed

definitely not uphill tho but if you use the gearing to your advantage they pull better than 4bd1's up long slow hills at 80+kph esp into into a headwind

it's a regular occurrence on the di'agular highway when i am coming home from wattlemere

My vote would be for the Td5, last and best engine that Land Rover designed themselves. I could be biaised as I have two, a D2 and fender. I have had a 200tdi which was good, but more power (remapped) plus the traction control in the Td5s makes them superior. Don't be scared of the electrics, if you can get a 15p engine (2003 on), the 10p model had the issues mentioned by others.

I have learning and doing all of the maintenance on the td5s myself, there are some great online resources such as discovery2.co.uk and trailerfitter's toolbox.

Good luck finding one as prices have jumped during Covid.
