Gets a mention in this older thread, too: https://www.fordownersclub.com/forums/topic/98500-ecoboost-low-oil-pressure/ It would be helpful for clarity to see a diagram of the oil circulation. There seem to be loads on the web for engines of all kinds, but I've not found one for the 1.0 ecoboost. 1 Quote Link to comment Share on other sites More sharing options...

Tizer Posted April 11 Share Posted April 11 1 hour ago, TomsFocus said: That information came from Wilco...so I would generally trust it. Thanks Tom, I thought you meant the Pump was designed to completely bypass the Filter. oil Filters have always had Bypass Valves incorporated in them for as long as I remember, even the Canisters of replaceable paper ones and judging by the strength of their Springs, the Filter would need to be very clogged up for them to open and there would still be a degree of filtration of the oil because the paper extends to to outside of the canister, it is not a complete bypass. 2 Quote Link to comment Share on other sites More sharing options...
Tizer Posted April 11 Share Posted April 11 Further to an earlier post and for any doubters, here is a photo of the Servo Vacuum Sensor on my car. I don't know if the 1.0 Engined cars are the same. It’s the white connector at the bottom of the Servo. Quote Link to comment Share on other sites More sharing options...
dontpannic Posted April 12 Share Posted April 12 So please indulge my ignorance - how is the vacuum pump powered? Is it spun by oil pressure? I would have thought that it was only lubricated by engine oil, so would need to be run for a fairly significant amount of time with a blocked oil feed for it to seize and stop generating vacuum? Unless I'm wrong and it's powered by pressurised oil. If it's the former then I heavily suspect that other symptoms would rear their heads first before the vacuum pump seizes and stops the brake assistance...

RayC333 Posted April 13 Share Posted April 13 Couple of photos of debris. One of vacuum pump gauze blockage (not mine, but of one that failed) and one of the debris I removed from my own turbocharger gauze filter (wrecked the turbo). 1 2 Quote Link to comment Share on other sites More sharing options...
Botus Posted April 13 Share Posted April 13 I blame the American's and their dam consumer rights and class action annoyance - otherwise all the designed to fail stuff would be making Ford Europe the money just like the accountants expected - no wonder they have to move to budget suspension these days Quote Link to comment Share on other sites More sharing options...
Tizer Posted April 13 Share Posted April 13 On the subject of Gauze Filters getting blocked, it is not just cars with Wet Belts that suffer from this. The early1.6 TDCI Turbos had a high failure rate because the Gauze got blocked. Ford's official fix for this was to remove the Gauze after replacing Turbo and Pipework and the Gauze was never fitted to later Engines - These Engines did not have Wet Belts. 1 Quote Link to comment Share on other sites More sharing options...

Awesome, so I guess my next query is if it’s mechanically driven by the camshaft and lubricated by the oil, if shredded parts of the belt get through the sump pickup and the gauze on the pump feed gets blocked then surely it’ll start exhibiting symptoms of failure well in advance of it failing to produce vacuum. Unless of course I’m being really dim and missing something obvious. 1 Quote Link to comment Share on other sites More sharing options...

Yes. I was checking mine the other day, still nice and clean after its 12 month service at an official Ford dealer using the correct oil according to the invoice. I've used them for years, and am pretty confident they use the right stuff, but how do you really know, particularly if using a non-franchise garage?

Given that you get a warning for not combing your hair (joking but you know what I mean) you would think so, but I've been having a search out of curiosity and only seen mention on VW, Audi, Skoda, etc forums. I have experienced servo failure on a Ford years ago (leak in vacuum pipe) but that was obviously long before all this warning stuff. Anyone know the answer to this one? 1 Quote Link to comment Share on other sites More sharing options...
TomsFocus Posted April 22 Share Posted April 22 It only takes two seconds to pull the vac pipe off and test it... Although I must admit I don't think I've ever seen a servo warning on a Ford, or even a fault code for it. Tizer's photo was the first I'd heard of them on the Mk4 Focus. 1 Quote Link to comment Share on other sites More sharing options...

I haven't pulled the Vacuum Pipe off to prove a point but when I last had FORScan running I did check the Vacuum in the Servo and it sits in the high 90's constantly and drops about 20 when braking. 1 Quote Link to comment Share on other sites More sharing options...
iantt Posted April 22 Share Posted April 22 Know there's a warning message to stop safely. 🤣🤣. shows on transit when one of the vacuum sensors fail electrically or looses vacuum. Guess other models similar message. 1 1 Quote Link to comment Share on other sites More sharing options...
