2013 Defender 110 Puma 2.2 SW Santorini Black

Puma 2.2 Engine - replacement or rebuild.

Good afternoon all,

My 110 recently broke down on the dual carriageway.
The car felt very juddery, then the revs shot up and I lost all power despite the engine still running. Looking under the bonnet, there was a lot of oil on the underside of the bonnet and covering the engine.

Initial inspections from a defender specialist seem to show that a piston failure has meant that oil has been pulled through the engine, into the turbo etc.

Now I'm faced with the decision of having the current engine rebuilt, finding a refurbished or low milage 2.2 puma engine to replace it with, or going for a different engine altogether.

Has anyone else had this issue, and what is the best route in terms of both reliability and maintaining value going forwards?

Any advice greatly appreciated!

Thanks.

As another option a new base 2.2 engine would be circa £5k inc vat , plus fitting.

Many will advocate an M57 conversation, but that can still be expensive and invariably involves getting a used engine. Some will advocate an LS3 or other V8, but that will require a lot of cash.

As for rebuilding your existing engine, it all depends on how much damage has been caused, and how much potential future failures have been enhanced due to the current identified damage. It’s all a bit of a risk as additional damage can be identified as the rebuild gets underway and before you know it you could have spent as much rebuilding your engines as you would have buying a new base engine.

As for a refurbished engine or used engine, again it’s a risk as you really don’t know their history and if they will last.

So if not going for a different engine, in your situation I would most likely go for a new 2.2 engine. I did think about a new 2.4 , as you can then get rid of the DPF, do an EGR delete, add a catch can and likely get 250k miles out of it. However that would require swapping ECUs, loom, IPAC etc etc, so costly and probably not worth it.

Ps did you have a map on your engine ?

Apart from the complexity of the conversion, new 2.4 engines are exceptionally hard to find at the moment for some reason.

I'd either get a new 2.2, or I'd get a pre-owned 2.2 and then strip the old one with a view to rebuilding it if practicable.

I've read numerous times on here that the Puma engine doesn't rebuild well. I've no idea why that is, but it's be interesting to see if anyone has had one rebuilt and had long service out of it. 2007 110 TDCi Station Wagon XS

I am pretty sure that the problem is the people rebuilding them not the engine.

There is nothing special about the engine.

Thanks for the replies all.

No I didn't have a map on it, all completely standard. I've only owned it for a year.

I agree a new engine looks like the way to go, would one from a company like Ivor Searle be a good option? Re-manufactured but not as expensive as a new engine.

2012 Defender 110 Puma 2.2 USW Orkney Grey

My second engine lasted 60,000 miles, the first only 12,000. Last time I looked at the M57 option, but only secondhand engines available, all of unknown provenance.

Next time, I'll probably go for another 2.2. When it works, it suits the vehicle reasonably well. I have another car to go fast in.

One reason could be many 2.4 engines (and 2.2s as well) are being built in China and sold somewhere where the old transit is still in use.

Anyway, 2 years ago I had to buy a new 2.2 stripped engine for a 110" and it came through Turner Engineers. Label showed this Ford engine was assembled in South Africa. Puma 110" SW

I would have thought a used engine would be the cheapest option as a replacement. Then probably a rebuild, but depends what kind of rebuild you go for. I suspect most of the engine is likely fine and to make it run would only need 'x' amount doing to it. But many will spend more on a rebuild replacing everything.

What are you goals/budget?

Do you want to keep the vehicle? Do you want to improve the vehicle? Or do you only want to patch it together to sell it on?

There are lots of engine options out there.

You'd need to sit down and work out prices.

The 3.2 version of the Puma engine is meant to be a fairly easy swap. I suspect this would cost only slightly more than sourcing a 2.2 engine, but give a reasonable increase in bhp & torque.

There is a company offering a Td5 conversion kit. Which might be an interesting option, Td5 engines can be had a lot cheaper, although I expect it wouldn't be cheaper all said an done when you include the conversion kit.

BMW M57, although I'd expect this to cost more than the above options, but a common swap.

Chevy LS swap, similar or more than an M57, really depends how cheap you could source an engine.

Lots and lots of other engine options.

If you don't really plan on keeping, might be worth considering selling as is too... might be cheaper/less hassle than repairing.
