I have two failures. Both due to oil starvation. 1st one the oil pump disintegrated second a small piece of what appeared to be black Bakelite type plastic blocked a piston cooling jet. I personally rebuilt after each failure without having the block machined just rehoned at home.the failures were over 25k miles apart so am assuming unrelated I have access to proper measuring equipment and all was still in tolerances. This shows how some parts/systems are weak but others are more resilient.
Lessons learned
1. Change the oil pump from the variable veined type to the geared type to avoid this type of failure and then at 50 60 k intervals
2. Replace oil pick up plastic tube with new anytime the sump is off to avoid the second type of failure as this is where i suspect the plastic came from

Hi Siwynne,

Can you explain more please, especially on point 1. Any photos or part numbers?

The 2.4 has a geared pump without a small pipe. I bought a pump and blanking plug off a local transit expert who changes the pumps as a service item. I don’t have a part no but will look to find some

2015 Defender 110 Puma 2.2 XS CSW Bronze Green

I have a OBD reader showing engine data, mainly temperatures. When pulling up hill in 6th gear at low RPM the temps shoot up; not so good for the engine. I always change down, more revs, more oil and coolant flow equals lowers temps.

I also use Millers diesel additive on most tank fill ups. Which reminds me I need to get some more.

Personally I think that the quality of the engine oil, make of filter (oil, fuel & air) and frequency of oil and filter changes are the main factor that dictate engine longlivity.

I only use Castrol Magnatec A5 oil and when it comes to filters I only fit genuine Land Rover or Mann. Engine service is 5000 miles or yearly. I also change the fuel and air filter at the same time. I know that this is overkill but filters are cheaper than replacement engines..

Does anyone on here add any oil additives?

2015 Defender 90 Puma 2.2 XS CSW Corris Grey

I had a 2.2 transit tipper it was remapped but it was really economical as well as fast. A year or so after remapping I done a mpg run over a few days trying to achieve max mpg and like a fool labouring the engine. It holed a piston. These engines are van engines made to reved, made to fly up and down streets in 2nd gear doing delivery's. I'll never make that mistake again.

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?

Most of the early Pumas for sale in the internet are near or even above 200 K - Transit vans of that âge have even higher mileages.

Very few did in deed replace engines / injectors

So a more recent Puma should perform like so

It’s just typical internet talk where only the failed ones make threads. There are millions of these transit engines in vehicles over the world. We are talking a tiny % of failures in the total. 2008 2.4 110 Utility Station Wagon XS.

No, it is actually a Genuine Parts one bought probably c.2015, by which time LR had more or less managed to remember how to make a driven plate. It has lasted a lot longer than I expected, and has had very little springiness for quite some time.

I already have its replacement waiting for when the time comes, which is a Transit 4x4 clutch.

I’m happy with mine the Sachs one, I has quite bad luck with the LR ones, they just didn’t last but also included slave failure which was the 2.4 original fitment. The 2.2 system seems better. Touch wood. Chillin In The Backwoods🇬🇧🇺🇸

The 2.2 clutch really is "better". I had to replace the the master. But I'm still on my original 2012 clutch and 150K. 2 independant mécanos confirmed that I do not have to replace witin the next 2 years (after test drive).

150k km or miles?

FWIW, my MY2009 Puma 2.4 Defender 90 is still on its original clutch (short of 120k km) “A Land Rover immobilized is a moral defeat for the driver and bad publicity for the vehicle, […] it's up to you to do justice to your Land Rover!” - Land Rover Driving Technique.

I.think the puma is a very good engine I've had them since 2000 when the first 2.4s and 2.0 came out in the transit the 2.4s back then where tddi rather than tdci and had a bosch vp fuel pump that was basically the same fuel pump as the 300tdo uses.
Puma is probably the best engine ever fitted to a transit.

The 2.5 DI on the Transit MK2 is a very good engine, too.
