salsheikh Posted July 16, 2012 Share Posted July 16, 2012 Guys, where is the dump valve on the TDCI's. I saw a few Mondeo TDCI's and they had all changed their dump valves and it sounded rather nice but I didnt get a chance to ask what they had changed it to and how difficult it was. any ideas?

oilburner79 Posted July 16, 2012 Share Posted July 16, 2012 I wouldn't bother as a dump valve on a diesel actually makes the car slower as it purges charged air from the intake 1 Quote Link to comment Share on other sites More sharing options...
raskL Posted July 16, 2012 Share Posted July 16, 2012 diesels dont have dump valves as standard the ford focus diesels use a recirculation valve infact all diesels do so fitting a dump valve would only cause issues i.e engine management lights , and drops in performance. i think they sell aftermarket recirc valves that are louder etc but im no expert on them , have a search around 1 Quote Link to comment Share on other sites More sharing options...
stef123 Posted July 16, 2012 Share Posted July 16, 2012 as above, it wont have a dump valve as diesels are free breathers. 1 Quote Link to comment Share on other sites More sharing options...
salsheikh Posted July 16, 2012 Author Share Posted July 16, 2012 sorry my bad. i should have put Blow Off Valve (BOV). I need to do some research....but feel free to share any info you may have. Quote Link to comment Share on other sites More sharing options...
raskL Posted July 16, 2012 Share Posted July 16, 2012 its the same thing mate, basically the pressure is released to atmosphere when foot comes off accelaretor, as i said id look for a recirculation valve that makes a noise if you do some exhaust work youll hear that sound your looking for quite clearly downpipe / silencer replacement with a straight pipe, check : http://www.european-parts.net/catalog/index.php/cPath/58_82 1 Quote Link to comment Share on other sites More sharing options...
welshwizard Posted December 10, 2017 Share Posted December 10, 2017 hi the bov will work on any turbo engine as all turbo's need the lag taken away, it's a question of right dump valve in the right place the same goes for boost valve.

Lenny Posted November 26, 2019 Share Posted November 26, 2019 In an economical world of variable vain turbos through there design; theres very little excess pressure to be expelled through a blow off valve I'm not a mechanic nor do I want to be 😅 I make more money as a pharmaceutical technician 1 Quote Link to comment Share on other sites More sharing options...

Thanks Isetta...now I've got 'Lets do the time warp again' going round my head... It was definitely worth signing up just to bump a 2012 thread arguing against someone who hasn't been here for years. Interesting first and only post anyway! 2 Quote Link to comment Share on other sites More sharing options...

teamduck92 Posted January 28, 2023 Share Posted January 28, 2023 I have a ford focus 1.6 sport and for some reason the turbo has turned into a dump valve as every time I realise the pedal the car dumps pressure into the air... What could be broken or damaged that I need to locate and replace Quote Link to comment Share on other sites More sharing options...
