Engine cut out on idle,tried to restart but it just spins over easily, compression 200psi on all cylinders, timming belts good all lined up?

Any help would be greatly appreciated

Since you say this is a 2025 Transit, you will have to let the Ford dealer sort it or otherwise void the warranty.

 

PS. your profile says it is a 2022 model 🤔

It's a 2022 and 70000 mils so out of warranty😪

It would be a good idea to correct the title of the thread which says it's a 2025 model.

Now we know it's a 2022 model with 70,000 miles, it is more than likely the wet timing belt has snapped. Which sadly means the engine is almost certainly scrap.

Ford recommends replacement at 100,000 miles or 6 years, but because of early failures, even earlier replacement, around 80,000-90,000 miles, is often suggested

Timing belts intact no signs of deterioration ,timing is good,no codes showing

How do you know ?

You would have to take the engine apart in order to see the wet timing belt.

If it's making compression, the belt must at least still be connected.  However 200psi does sound low for a diesel to me.  Does anyone know the official figure for the 2.0 EcoBlue?

A common problem with the EcoBlue 2.0 is that the teeth get ripped off the belt. When the engine is running at speed it seems the engine is able to deal with some missing teeth and maintain timing, but at lower RPM if there is a group of teeth missing the timing will jump and the engine will likely stall.

I've seen a belt change on an 'AA' EcoBlue 2.0 which had so many teeth missing it was a wonder that it had run as long as it did.

According to the garage the belts in good condition and a timming is good,,could this be burnt out valve seals? I find it strange that it was running fine . I just started it from cold no problem left it idling for a few minutes and it cut out. Garage reckons it needs a new engine but I'm thinking they just can't confirm what the problem is 

You need Diagnose Dan or similar to properly diagnose and not just guess, for example:

And was Forscan used or ?

At the risk of sounding like a stuck record:

Can they demonstrate how they were able to view the condition of the whole timing belt ? 🤔

They say they've taken the cover off,   they charge £85hr and they recon that was the first thing they done as you know the belts are know to fail

🤣🤣🤣

The cover is bonded to the engine and can't be removed without destroying it.

Think you need to find a different garage.

Spoke to the garage and they reckon they can tell the timing is OK through live data ? Is this true?

So is the engine now running ?

There wouldn't be much live data with a dead engine. If they are 100% happy the timing is spot on, and the wet timing belt is in tip top condition with no missing teeth have they given any thoughts as to what the problem is ?

The engine is a crank no start, I guess they getting crank and camshaft readings ,,,they aren't comming back with the actual problem just saying it needs a new engine. Is there a way they can check the timing just cranking over from the live data? Don't really won't to condemn this engine.

Thank God they don't do heart transplants 🤣

So to get this clear, they've no idea what's wrong, just that a new engine will fix it !!!!   That would be so funny if it wasn't for the fact they will be expecting you to pay.

If the wet timing belt has snapped or more likely the teeth have been ripped off then there is more than a 50% chance you will need a new engine.

The big 'however' is if the garage are sticking with the idea that the timing is fine, the weltbelt which they claim to have inspected, is also fine, and that all cylinders have compression, (and I would hope they have checked the injectors) but they can offer no explanation as to what the problem might be.

Time to change garages before buying a new engine.

You need someone like Diagnose Dan or:

To get right down to the nitty gritty without fitting a new engine (ideally)

If there is a problem with the belt would there still be 200 psi on all for cylinders?

Thanks for your help on this 👍

To be honest, I would expect to see some differences in the cylinders but I have little confidence that the test will have been carried out correctly. I'll try and find the video of the Transit 2.0 with a wrecked wetbelt just so you can see what's involved.

 

I've spoken to the garage this morning and they gave me the compression readings

Cylinder 1. 225psi

                2. 200psi

               3. 220psi

               4. 180psi.

They also say that they done a smoke test through the inlet and smoke came out of the oil filler opening .

Would this smoke test confirm internal engine damage or is this garage not trust worthy?

Seems the engine has internal damage, and no I wouldn't be using the garage.

Compression seems far too low for a diesel, what do you think @TomsFocus ?

Sounds low to me as well.  But I haven't seen the official figures for this engine.

Smoke test will depend on what they mean by inlet.  If they're just filling up the air intake then it could pass through the crank breather hose.

Ultimately it probably does need an engine.  But I also wouldn't trust this garage to fit it.

In my opinion all compression readings are considerably low for a Diesel engine. I would expect compression reading of about 350 PSI for this type of engine.

The deviation between the highest and lowest readings is also considerable. Way too much for a healthy engine in my opinion.


This indicates a mechanical engine problem. The only reliable way to diagnose the problem is by disassembling the engine.
