Ecoboost low oil pressure

Recommended Posts

Hi 

thanks for the reply. 

The since I have changed the oil and filter the fault has now cleared the cam shaft sensor, strange.. on start up from cold it sound ok but as the oil gets hotter and thinner it sounds a bit noisy, the engine light keeps going on and off more so on when you rev it up. Do you know which one the cam shaft sensor is as from looking at the top of the engine it has two. From past experience on my zetec that engine only has one sensor on the inlet cam side.

 

regards

Well the car is now back on the road. I took the sump off the engine, and found the oil pump looking like this:

The inlet has a mesh which is completely clogged up with some form of black debris. This is some of what I removed from the pump inlet:

It's not magnetic. My best guess is that the previous owner used either the wrong oil or didn't change the oil as frequently as they should - odd as I bought the car with a full history. My other theory is that it is some RTV silicone broken off from overspill from the sump gasket.

Having fitted a new pump, the car now drives normally. Oil pressure builds straightaway - noticeably faster than it used to. The turbocharger is still delivering plenty of boost having monitored the inlet manifold pressure during a short drive. I did find about 50ml of oil in the intercooler pipe, so the seals may have degraded - I'll keep an eye on it.

Having had this issue, I'm tempted to get a fibre-scope to check the condition of the oil pump inlet through the sump plug at future service intervals. Given its proximity to the sump plug, I'm toying with the idea of making a thin tube up to facilitate cleaning of the pump inlet without having to drop the sump.

Learning points:

1) Based on the crud I found, it's possible that these engines are not very tolerant to being poorly maintained. Regular oil changes with manufacturers spec oil probably the way to go to prevent this!

2) If your engine oil pressure light doesn't go out immediately, and if the low oil pressure alarm occasionally comes on momentarily when starting the engine, then this is indicative of the oil pump becoming clogged up. Get it sorted before it gets worse

The turbocharger water pipes cleaned up ok with a wire brush on a die grinder:

I've now coated the pipes with some VHT enamel paint, so I'm expecting further corrosion will be prevented.

Hi all,

 I'm new here..( brought here by a search of low oil pressure in a 2013 Fiesta. - its a far from common failure..)

I've inherited the car from my niece,

 owned from new with (FSH) .. at least bills for regular servicing,

it flagged up STOP on m-way. was limped into services.. sounded awfual after a 30 min "rest" .. so was recovered.

recovery garage quoted £4k for a new engine ( value of car..)

 

 so it's over to me..

 

oil is BLACK .. considering it's supposedly well cared for ..and been stood fo a while

so the CRUD blocking the strainer /pick-up sounds plausible.

 

 OK so how much work is dropping the sump?,

 seems worth doing..maybe even a £35 ebay pump whilst it's apart..

refill with warm oil from another car, crank - see what occurrs

 

access to the car is a tad awkward.. so would like something I could achieve in a morning..

 

any comments most welcome ,

 my FORD experience went through  KENT , Pinto to CVH..  ( not a fan of Japanese stuff)

so have done Italian for a couple of decades.. ( thought this fiesta was a Ka with a Fiat FIRE engine..)

 

cheers.

See above comment for the amount of work involved. Mainly it's removing all the exhaust components which I found quite awkward. I would say a day is more like it than a morning, but maybe I'm a slow mechanic!

I'm looking at doing a fairly thorough job..

 but feel I've a slim chance of success.. too long run with low pressure  :(

but I may as well try this before paying somebody to change to a good used engine.

 

is there a parts fische I can access..?   looking at what seals the sump .. a proper gasket.. or essentially BONDED in place  ;)

as Importantly,

 has your ecoboost behaved in the months since your post?

Yes, had no oil pressure problems since. The auto stop/start has a mind of its own and it's totally gutless, but neither related to the oil I suspect!

good to hear.

 

the RTV debris comment helped know what sump sealant is required.

 

may be weeks before I get to do this job.. but great to have  a walk-through and good pics.

 

anybody got a link to an online parts list / manual.. checking bits I buy will actually fit,

 

Cheers.

UPDATE -  Spoke to an RAC recovery tech.

 apparently this is a well known issue,  brought on by the extra-fine mesh . not coping with poor oil quality in neglegted engines.

 

so definitely my 1st port of call.
