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.

A Citroen DS3 with its Wetbelt Failing!

When your engine oil warning light comes on most people just think the “the engine just needs a bit of oil!” but in some cases it can be a little more serious.

Imagine somebody restricting the the blood flow around your body and how that will affect your performance?

The same goes for your cars engine, if you restrict its oil flow you are causing un-necessary wear and stress on its moving parts!

In the case of any Wetbelt failure what happens is the rubber debris from the Wetbelt collects in the oil and gets sucked up by the oil pump and trapped in the oil pump strainer – watch the video to see what we mean.

Over time the oil pump strainer starts to become blocked causing less oil to be pumped around the engine and the oil pressure to drop.

Most cases the oil warning light does exactly what its supposed to do and warn you before its to late.

That was the case for this Citroen DS3, we got to it just in time before the belt failed completely.

The owner of this car has kept up with its service schedule as required (with another Garage) so all we can suspect is that the wrong oil has been used as it only has 53,000 miles on it.

2019 Ford Ranger 3.2 Low Oil Pressure Light On After Service

We recently came across a problem in the Garage which we have not come across before, which was the ‘Low Oil Pressure’ warning light coming on after replacing the Oil and Filter on a 2019 Ford Ranger 3.2.

After searching on a couple of the Motor Trade platforms we use it seemed that we were not the first to come across this problem, but we spoke to our local Ford Dealer and they said they knew nothing about it.

There was apparently a technical bulletin which had gone out to dealers saying that if the oil and filter change was not completed within fifteen minutes this problem would occur due to the oil pump draining and not being able to re-bleed itself.

Personally we believe this is a poor design, when we drain the old oil from your car we want to remove as much of the old oil as possible (obviously some oil will stay in certain places of the engine) allowing the new oil not to be diluted with it.

In this particular case the only way we could bleed the oil pump was to flood it, we added five litres more oil than specified to bring the level inside the sump up to the bottom of the oil pump meaning it didn’t have to pull the oil up but just push it.

Once we had got the oil pressure up we drained off the extra five litres of oil, road tested the car and then re-checked the level.
