RichHorrocks Posted January 9, 2016 Share Posted January 9, 2016 Hi folks, I'm looking at blanking off the EGR valve on my Mark 2 Focus. Perhaps a silly question, but at which end of the EGR system is it best to do the blanking? At the valve end itself, which is at the top of the engine and easy to get to, or at the end where it comes off the exhaust manifold? If you blank the manifold end you bypass the whole cooler system, but does that matter? Thanks in advance. Quote Link to comment Share on other sites More sharing options...
MONDEO TXS 2.2 Posted January 9, 2016 Share Posted January 9, 2016 Either end will be ok - I have blanked my vehicles at the EGRV with no issues - more importantly make sure the blanking plate is solid 2 - 3 mm steel ( no holes in it ) Quote Link to comment Share on other sites More sharing options...
dezwez Posted January 9, 2016 Share Posted January 9, 2016 stainless steel if you can get it of eBay :) Quote Link to comment Share on other sites More sharing options...
joe bloggs Posted January 9, 2016 Share Posted January 9, 2016 ok, enlighten me please, what are the benefits of blanking off the egr? Quote Link to comment Share on other sites More sharing options...
MONDEO TXS 2.2 Posted January 9, 2016 Share Posted January 9, 2016 ok, enlighten me please, what are the benefits of blanking off the egr? You'll prevent the recirculated exhaust gases clogging up your EGRV & intake manifold with a congealed gunk of oil & carbon which will kill your engine & turbo sooner rather than later. Other benefits include a cleaner diesel burn, improved mpg & power output :) Quote Link to comment Share on other sites More sharing options...
biff55 Posted January 9, 2016 Share Posted January 9, 2016 ok, enlighten me please, what are the benefits of blanking off the egr? you will deny your local ford dealers the opportunity to empty your wallet when it needs changing cos its full of sludge...... :-D 2 Quote Link to comment Share on other sites More sharing options...
ajzetecs Posted January 9, 2016 Share Posted January 9, 2016 turbo will kick in quicker than before fitted, my 18 tdci is very jerky under steady speed under 2k revs when havnt got blank fitted, dont know why but is better and smoother with it fitted Quote Link to comment Share on other sites More sharing options...

MONDEO TXS 2.2 Posted January 10, 2016 Share Posted January 10, 2016 ok, enlighten me please, what are the benefits of blanking off the egr? To add - it's not worth doing on a petrol engine & could actually do more harm than good due to increased combustion temperatures 1 Quote Link to comment Share on other sites More sharing options...
biff55 Posted January 10, 2016 Share Posted January 10, 2016 To add - it's not worth doing on a petrol engine & could actually do more harm than good due to increased combustion temperatures plus the egr valve is rarely a problem on petrol engines as petrol burns much more cleanly than diesel with significantly less oil and carbon build up on the intake components. 1 Quote Link to comment Share on other sites More sharing options...

RichHorrocks Posted January 11, 2016 Author Share Posted January 11, 2016 Okay, so the consensus seems to be to block things off at the valve itself, and not worry about the connection to the exhaust manifold. Thanks folks :) Quote Link to comment Share on other sites More sharing options...
Dee_82 Posted January 11, 2016 Share Posted January 11, 2016 id have thought blocking an EGR on a petrol might have a noticeable effect on emissions as well? Quote Link to comment Share on other sites More sharing options...
