Ford 1.0 EcoBoost Low Oil Pressure – Common Cause Explained

The Ford 1.0 EcoBoost engine is used in many Ford models including the Fiesta, Focus, Puma, B-Max, C-Max and more. While these engines are efficient and powerful for their size, they are also known for a serious oil system problem that can lead to engine failure.

One of the most common warnings owners see is the low oil pressure warning light.

If this happens, the engine should be stopped immediately, because continuing to drive can cause severe engine damage in a very short time.

The Common Cause

On the 1.0 EcoBoost engine, the oil pump is driven by a belt inside the engine.

This is often referred to as the oil pump belt or part of the wet belt system, because the belt runs inside the engine and operates in oil.

Over time this belt can:

Degrade in the engine oil
Shed material into the oil system
Lose tension or fail completely

When this happens the oil pump cannot maintain proper oil pressure, which can trigger the low oil pressure warning light.

In severe cases this can lead to:

Oil starvation
Engine bearing damage
Complete engine failure

Symptoms to Watch For

Some of the common symptoms include:

Low oil pressure warning light
Engine warning messages
Unusual engine noise
Poor lubrication inside the engine
Oil contamination from belt material

If these symptoms appear, the vehicle should be checked immediately.

Skoda 1.6 tdi timing tensioner failure Part one

This week was interesting. Having replaced this belt a couple of years ago on a Skoda Octavia 1.6 Diesel,the customer came in with a terrible noise. So it was time to investigate. As you can see from the pictures upon stripping it down I was horrified by what I saw. As you can clearly see the bearing as totally failed. It was surprising to know this car was actually running. Totally amazed that it was running. You can see that the heat from the faulty bearing has over heated melting the plastic on the tensioner. Here you can see it after removal. The obvious thing to do now was replace the timing belt kit using the correct Volkswagen locking tools to see how it runs. OK so I will put you out of suspense. The car runs but makes a terrible noise. So unfortunately for the customer the Skoda will be stripped for further investigation. I have no doubt there will be internal damage but I expected this anyway. I will follow up with thi...

Cheap tools or expensive premium tools?

OK so I get the argument. I got the best tools, snap on, Mac tools etc with a lifetime guarantee! The other guy, your mate says “Look at these tools I just bought really cheap, why pay the price you paid when you can have them for a fraction of the price”. In my experience after 25 years in the motor trade I have come to a conclusion. But before I reveal, I have to say at the start of my time as a mechanic,I was snap on tools all the way. Unfortunately now after paying a stupid amount for tools it doesn’t matter. What good is a tool you Left on the bulkhead under the bonnet costing £60, or a tool that cost you £6. I know the answer. It’s no good. But the £6 one is easily replaceable. What’s more is that in my time in the trade I have found the quality to be almost as good as some premium tools. Not to say it’s the same. To conclude if you are totally obsessed with your tools and you put them away after every use definitely consider the premium tool. But if you’re the busy me...
