FORD AT AARONS AUTOS

What caused this Vacuum pump to fail?

This Ford Fiesta Ecoboost was recovered into us after the customer noticed his oil warning light was staying on whilst the car was still running.

When we got the car into the workshop we always like to give them a quick start just to see if there are any other faults we need to look at whilst stripping it down.

In this case we noticed there was no vacuum assistance for the brakes and after a quick look at the vacuum pump i t became apparent there was a problem.

So, what caused this Vacuum pump to fail?

The rubber debris from the failing wetbelt had traveled through the oil galleries and managed to block the little gauze filter going into the vacuum pump causing it to starve itself of oil.

The engine oil in this particular engine had not been changed regularly and possibly not even been the correct specification oil.

Once we had carried out our wetbelt replacement process which in this case included a new oil pump and replaced the vacuum pump the car ran perfect.

We have recommended the customer has another oil change within 2000 miles just to ensure any rubber particles which we couldn’t remove will be flushed through the system and then removed.

Is the 2018 onwards EcoBoost any different?

The early EcoBoost engine has definitely got a following but probably for the wrong reason so is the later EcoBoost engine any better?

Well, yes and no, Ford have made a few changes to the engine the main one being a new oil pump.

The new oil pump is a bigger unit which incorporates a balance shaft to reduce vibration.

And the oil pump drive belt now has a tensioner instead of being a push fit.

Are they more reliable?

Again like the earlier engines if they are well serviced using the correct oil they are fine.

If on the other hand you miss your service intervals or use the incorrect oil you will have problems!

Ford haven’t really done anything to prevent the rubber debris caused by the degrading belts from blocking the oil pump and starving the engines of oil.

This particular 2018 Fiesta Ecoboost with only 30,000 miles on it was brought into us because of a lack of power and the engine being noisy.

As you can see the wetbelt is in very poor condition and was breaking up.

Because bits of rubber had blocked the oil pump it caused the turbo to fail due to oil starvation.

Once all necessary parts had been replaced the car ran as sweet as a nut.

These problems could have been avoided if the car had been serviced properly and the correct oil had been used.

Ford EcoBoost Cam Pulley Failure

This Fiesta was recovered into us with its oil warning lamp on and a horrendous noise coming from its engine.

Once we had stripped the engine we could see the cause of the noise, the inlet cam pulley had been starved of oil which was allowing excessive free play (variable timing pulley) which as you can imagine is not great when the engine is running!

The cause of the oil starvation was quiet apparent when looking at the oil pump pick up, it was completely blocked with rubber debris from the failing wet belt.

The customer was very honest with us and admitted she had not had the car serviced regularly which would of allowed some of the rubber to be cleaned out with an oil change instead of blocking the oil pump.

Fiesta EcoBoost oil warning light on?

This Ford Fiesta 1.0 EcoBoost was brought into us with its oil pressure warning light on and its engine sounding a bit noisier than it should.

After stripping the engine our previous guesses turned out to be correct, the wetbelt had been degrading (as they do over time) leaving deposits of rubber in the oil which were being sucked into the oil pump pick up and causing it to block subsequently causing low oil pressure.

OIL PICK UP FULL OF RUBBER

If this problem is left to long it can cause serious engine damage as it is starving the engine of its lubrication.

On this EcoBoost engine we replaced its wetbelt kit and oil pump belt and also decided it would be a good idea to replace the oil pump itself rather than clean out the pick up (as it was so bad).

Once the job was completed it was time to see if the repair had worked and turn the engine over on the key!!

Success, the engine started, oil warning light went out and it purred like a kitten.

WETBELT DEGRADED AND SPLITTING

We think the biggest issue with this particular engine was caused by a lack of servicing, we know the wetbelts degrade over time leaving rubber deposits in the oil but with regular oil changes most of those deposits would be removed from the engine and not be allowed to block the oil pick up.
