Peugeot 5008 2023 - Peugeot 1.2 engine - Melru

I'm considering purchasing a 2023 Peugeot 5008 with the 1.2 PureTech petrol engine. But I'm put off by the fact the rubber cambelt runs in oil.

I've heard quite a few horror stories of these belts failing with the debris clogging the oil strainer resulting in total engine failure.

My Sons own P208 suffered in this way, fortunately he listened to my advice and didn't drive until it was rectified.

The local Peugeot Dealer told me this has long been rectified and not to worry, however after 30 plus years in the motor trade I know oil and rubber don't mix.

Any advice would be appreciated

You believed them? I understand there's been around half-a-dozen fixes by updating the belts and oil specs. Haven't Ford reverted to a chain cam drive on their ecoboost (although retaining the in sump, oil pump drive belt)?

If you must buy it then the only advice I would give is:

1) Main dealer servicing exactly as per the official Peugeot service schedule & only top up with the correct spec of oil to Peugeot specification.

2) When its about to exit the original manufacturers 3 year warranty, consider buying the Peugeot extended warranty - make sure its the PEUGEOT UK extended warranty & not a dealer group backed one.

They are right. There are now hundreds of thousands of these cracking little engines all over the globe in many Stellantis models. We have one in our 2019 Peugeot 2008. There are virtually 'no horror stories' after 2018. The problem was due to the u/s early DAYCO belts which crumbled, especially if wrong spec cheap oil was used at oil changes.

, however after 30 plus years in the motor trade I know oil and rubber don't mix.

They do now. Oil and belt materials have improved considerably since the millennium. Just check your garage doesn't cut corners by using non-spec cheap oil. (I change it myself to ensure this doesn't happen).

Even without any years in the motor trade, but quite a few as a chemist, I would also avoid deliberately mixing oil and rubber. There are well-established ways to connect crank and cam shafts without asking for potential trouble. Stellantis have obviously had to spend time and money trying to make something work which has little real advantage.

Little real advantage? Are you serious? This excellent engine's reputation was hugely damaged by DAYCO's poor quality crumbling belts. Fortunately it has now been more or less restored but I think the effect on market share will be longlasting. Read all about it.....

If needing replacement I would never use a DAYCO belt. I'd go for a better one, e.g. Continental CT1228.....

John, you misunderstand me. The concept of running a 'rubber' belt in an oil-bath (rather than in lower-viscosity air) has little real advantage. I presume the intention was to reduce noise, but I may be wrong. If it had not been implemented, Stellantis would have avoided all the expense of finding a belt material able to stand up to running for years in hot oil !

......ah - presumably over a dry belt if I now understand correctly. I agree, but then - every little helps. With better cooling and less friction they are supposed to last longer as well as being quieter and more efficient. Of course, they don't actually run in an oil bath any more than a chain does. Anyway, I have no intention of changing ours unless it starts to look a bit iffy. Our old Focus dry belt lasted the life of the car (21yrs and 160,000+miles) as it was designed to do, so I'm going to see how long this wet belt lasts - although at around 6,000 miles a year I think it will probably outlast us.

That mantra, or something like it, is used by Tesco IIRC. It is often true, but so is the rule of Diminishing Returns, which I think applied in this case ! The search for a (very) marginal gain in efficiency was offset by hoping for a belt material able to survive long service intervals. Perhaps too many fingers were crossed ?

"I have no intention of changing ours"

The September issue of Car Mechanics (available free on Borrowbox via library membership) has an informative article on BIO with a step by step guide to replacement on a 208. Certainly not as straightforward as Fiat's FIRE, but not beyond the capability of a competent DIYer.

Was idly scanning a copy in Sainsbury's yesterday, rather surprised that it still existed, since it surely caters to a fast-dying breed, including me, until recently.

That engine isnt perhaps the worst example of cretinous/criminal conspiracy anti-maintenance design in there, though it is admittedly pretty bad.

IF I understood correctly from my quick scan, (and it does rather beggar belief) it details an oil change procedure for some VAG transmission which apparently has no accessible fill port. They detail filling it from the bottom via a hose from a raised oil reservoir.

How do you get the attachment off and the drain plug back on?

Well, apparently, you have to be quick.

One for the connoisseur, if true.

Reliable termination of economic lifespan seems a very significant advantage from a manufacturers perspective, although the legislative termination of IC engines in general may have reduced its utility in this context.

And what about PSA's previous disaster with stretched chains?

Then there's the flawed adblue tank system, and before that the flawed EOLYS system, and before that their recommendation that the DV6TED diesel engine could do 20,000 miles between oil changes. The blocked oil turbo feed line soon put paid to that.

PSA have been letting drivers down for years with stuff that wasn't properly long term tested - leaving poor sucker customers with the woes - usually just after the warranty has expired.

Being a former long time driver of them (various 205s, a 206, 307s, and a 407 over 30 years) I used to defend Peugeot until I was blue in the face - especially on electrics - but I won't any more.

Over 22+ years I owned 405, 406, 405, 206, 206 & then 308 T9 powered by the multiple award winning Purec*** 130 engine.

PSA " lack of " customer service attitude to a customer with a full Peugeot main dealer service history suffering from know Purec*** issues is the reason I wont ever buy anything from Stellantis again & I now own a Toyota.

Missus recently got a new Toyota as well.

I understand the Toyota Aygo also has one of these engines.

I wonder if they have somehow managed to overcome its inherent awfulness.

According to 'encycarpedia' the Toyota Aygo has a 3 cylinder 1.0 litre engine, as did 1.0 litre Yaris models.

Also used in Citroen C1 and Peugeot 1008, this was, I think, derived from (or similar to) the 1.0 3 cylinder engine in Daihatsu Charades.

No BIO in my Charade engine, (CB22) just the standard dry rubber band thingy.

Quite bad enough, thanks

My source for the Aygo having one was the Car Mechanics article mentioned above.

I don't suppose PSA were the only ones. Today's problem is that rushed developments are forced on makers by legislation connected with environmental demands of various sorts. Back in the day, makers could develop new engines at their own pace, do a bit of in-house testing, try to keep abreast of what others were up to, and hopefully have a successful launch - if the workforce were committed enough to put the bits together properly !

What's the problem with EOLYS apart from needing to be refilled at around 90k miles?
