Making a Puma engine last 200k
We all know the horror stories of the puma engines blowing up and needing replacement. But what general maintenance is required to get one to reach 200k or is it bad luck with injectors etc?

What does actually cause them to go wrong?

I may be looking to get a Puma 110 through work if the boss agrees to my idea so likely to be an example which has under 100k and I am likely to put another 100k on it in the next 4 years and would then look to purchase the vehicle for myself to avoid the new extortionate benefit in kind tax on a utility vehicle

The other option is a new Ford ranger or a dmax pickup to replace my current 3 year old dmax

Let me know your thoughts

I personally think it’s the remapped/tuned ones which tend to hole pistons etc. leaving the standard map on and having sympathy go a long way IMO.

As long as you do the maintenance like injectors seals and replace the leak off pipes etc while doing that job, regular oil changes and let it warm up properly then I can’t see any issues.

Going against the internet grain, I really like the Puma 2.4 engine. Its an uncomplicated engine and It’s a lovely torquey motor for daily driving and returns respectable mpg. 2008 2.4 110 Utility Station Wagon XS.

I’ve a chipped 2.2. Had a turbo go at 80k and a few sensors along the way. Still going strong at 169000. Just service once a year or at 10k miles.

Modern engines need to be used, I don’t hang around, quite often rev it to 3k, do proper motorway speed and regularly tow.

Be nice to break the 200k mark so probably another three years. Then the big question what engine or type motor would replace the 2.2. I’ll be upgrading the brakes first before it gets more power.

But they are becoming classic cars I’ve had mine 11 years in March. Not many people keep a ford ranger for 11 years. I know you can get the 3.2 ranger but hasn’t it got the same 2.2 but with more power than a standard defender. Hence why I got mine mapped to the same power as the ranger.

Do we? What horror stories are these? We know of a small number which have had issues, but we don't hear of the thousands which don't.

My 2007 has now done over 279,000.miles and almost all the engine is original. It has a BAS map.and pulls like the proverbial train. It get serviced occasionally but never does short journeys - it always gets thoroughly warmed up. I'm usually running at around 2.7 tonnes and quite often towing heavy trailers.

Completely agree! The 2.4 TDCi motor is probably the best engine in terms of fitness for purpose ever fitted to a Land Rover vehicle.

I love the 2.4 too and find it well suited to the 90/110 options and perfectly suited to towing too whilst being reasonable on fuel. My heavy 130 needed a little more umph though. Cheers

Had both 2.4 and 2.2. I had a a great 110 2.4 but my first 90 2.4 chuffed blue smoke from new. My first new 2.2 broke down loads. The 110 2.2 I have now is fine.

There’s hardly any difference between a good 2.4 or 2.2. Glad I brought one before they finished but would have been happy to keep DV10 XEM, that was also a good one. Amazing how different each one is. You can get good and bad of both engines.

I sold my 2.4 at 170000 miles.
Sold it to a mate…he has took it over 200k.
I used mine for everything from off-road to long European breaks…regularly towing.
It was serviced basically but regularly and never let us down
I’ve told my mate I’ll have it back in due course
The 2.4 engine is amazingly good. Make today a little better than yesterday but not so good as tomorrow....

Agree with Blackwolf.. the 2.4 its just a good fit for the defender, kinda like a modern day 200tdi for me.

I'm spoilt tho as have a 300tdi, td5 and 2.4 and while I love to drive them all the 2.4 is my daily...

This would be my work daily, which is normally about 2k a month as an agronomist so haring around the countryside, back lanes . If I got a new pickup I wouldn't be keeping it longer than 4 years due to the new BIK rules and wouldn't want to purchase it myself afterwards, whereas a 110 I would like to have the opportunity to buy it after the 4 year period and before I would get clobbered with over £6k a year tax bill.

The key failure point is injectors @ 150k (km) - get them replaced close to then and it should be good. The 2.2 is a very simple engine, it hates getting too hot, so watching EGT and Coolant Temps is a good idea.

Here in Australia, I have a bigger radiator (PWR), bigger intercooler, proper header tank etc. I'm in North Australia, so it gets hot. I dont know if you need to go that far in the UK. I have a 170hp BAS tune too.

Injectors I've seen kill engines, whilst the engine is cheap to replace (relatively) with a South African Ford motor, its easier to replace your injectors at or before 150k km.

Regular maintenance, good quaility fluids and learning to drive in the sweet spot will also help you.

The catastrophic failure stories seem to relate to holed and cracked pistons most often. Likely due to injector faults. It seems a bit over the top to change injectors as a service item but if you did them at 100k then had the ones that came out tested and reconditioned for the next time it wouldn’t cost a huge amount. It’s a pretty easy job to do and the new seals would also tackle a weak point.

Just done mine at 145k. I’ll do them again when (if) it gets to 200k. 2011 130 Utility Body

I haven’t replaced my injectors, they’ve not given me a reason to change them at 120k. Just new rocket gasket kit, injector seals and the leak off pipes. My injectors are silent and no smoke etc. I just put injector cleaner in every so often. 2008 2.4 110 Utility Station Wagon XS.
