tdci egr blanked now problems
hello
i blanked the egr valve off yesterday on my mondeo 2 litre tdci its an 03 reg
on a 40 mile round trip later i noticed a whine coming from the engine and it seamed like it was as i set off from stand still and truning the wheel .
when i got back home i looked under bonnet and found power steering fluid been leaking this only happened since i blanked egr valve off
anybody any ideas why this is ?
thank you

Yep. You're tryin to cut corners with an engine,designed with really tight tolerances. Im in same predicament with my gearbox synchros,but am spending a painful Ł1k to let ford do it,& get proper OEM parts. Dont like doing it, but i know i'll get another 100k out of this box,maybe more. Ive done the EGR blanking before,& about 4months later regretted it as it was only masking the real problem. Found that along with remapping & not havin upgraded icooler,there was bore-wash etc,& the engine was running at silly temps. Is your car remapped by the way?

Why not just get a second hand gearbox for a fraction of the cost? Even if you end up getting through three it will work out cheaper surely?

Erm, blanking the EGR does not cause bore wash.
EGR systems by their very nature recirculate shitty exhaust gasses back into the inlet manifold. Great when brand new for cutting emmisions but give it a few years and your egr valve, inlet manifold and inlet ports begin to block up with horrible deposits which causes a restriction, underperformance from teh engine and running problems.
To cure these problems you need to clean out the inlet system and blank the EGR off. This is then preventative for the future.
Simple.

"along with".not gonna argue
my point being you dont HAVE to blank your egr. Its the underlying problem thats causing it. I know about emissions blah blah. Believe me,your engine is worn,thats all

thats the reason folk end up spending twice as much. 2nd hand is false economy.Id rather pay 800-1000 and have a mint 100% running car with 100% working gearbox. Even some companies sellin refurbd boxes are fulla crap(just a 2nd hand box full stop) Same with egr blankin etc. Just get the fekin egr/manifold out n clean it. Ya's are all cutting corners,believe me

don't really want to get into a debate but blanking a egr valve isnt cutting corners.. and a engine rebuild isnt the solution either.
wulliegunn you've already admitted that you've sent your car to ford to get it sorted.. meaning you've never got your hands dirty and had a look at the effects the egr does to other components of the engine or taken the time to find out what the egr is?
my dad has the 2.2tdci and we had egr problems going into limp home mode.. we checked the codes of the car and it had a water temp sensor fault and a egr fault, as we'd just bought the car i fitted a new temp sensor and blanked of the egr so we could monitor the problem before paying for a new egr.
the blanked egr fixed the problems short term but as the cars ecu knew the egr was missing as soon as it realized there was no signal it would automatically put it back in limp mode.. on older models its a vacuum operated egr so limp mode shouldnt be affected.
in the end we changed the egr for a jaguar unit to save hassle of reseting limp mode, but when i changed it i removed the inlet manifold and the amount of carbon build up was horrible and realy shouldnt be in a inlet manifold and its only there due to the recycling of exhaust gases.. i gave every part a clean in the egr system to free up the solid carbon affecting components by restricting them from there intended size
ideally id like to blank the egr of and fit some sort of relay to trick the car into thinking its working.. saving the engine of being filled with carbon which will harm mpg and emissions more than a egr did to help them in the first place.. but no body has made that solution the closist you can get is this bypass kit but i believe limp home maystill be affected

apart from gearboxes I do 99% of my own work. I just choose to let the guy at ford strip my box n rebuild/refurb it wi new proper parts.Its about the only part of engine i WONT mess about with. This egr arguement aint goin anywhere as I cant prove that it is definitely not going to improve your smoke problem & i admit that,but at the same token,you cant prove either that its going to cure your smoke. I have a feeling it'll return,but hope youre right,as Ive owned a smokey 406 & it was embarrasing to drive at times,especially in summer at nights with headlights behind me
another thing,why not just clean it all out & refit?

Blanking the EGR isn't cutting corners. It's a way of preventing it from causing other issues with the engine. It's a badly designed component which works fine when new, but can quickly start to cause problems. It's more of a preventative, than a bodge.

100% agree I have been a mechanic for 25 years Vauxhall,saab,renault and fords suffer fron egr valves

On the earlier Euro3 Mondeos the EGR is vacuum operated, so not part of the ECU. I removed mine completely on the Mk3 I had. Got better MPG, better performance, and no downsides other than a slight increase the Hydrocarbon emissions.
On virtually all modern EGR-equipped diesels the EGR is best blanked off once the car gets past a couple of years of age.

I'm Finding My Feet Here Now
I blanked my EGR valve a couple of years ago. I have a 2007 ST TDCI. It runs much better and smoother. Only downside is engine management light on all of the time. I can live with that. To my mind, if there are cooling, or oil pressure problems or generator problems, these are covered by their own warning lights. , I would If the car seemed to be having another issue elsewhere I would have the codes read.
