I noticed from the recent posts concerning the blanking of the EGR Valve that there are those who advocate a blanking plate which would prohibit any air (or gases) from entering the intake manifold, as far as I can see on my TD, and others who use a blanking plug (coin or such) at the exhaust gas inlet, thus prohibiting only exhaust gases getting through.


Any thoughts on what is best.

PERSONALLY!!  I blank it at both ends !! main reason is you tend to forget just how hot the exhaust gases are, and just blanking it at the top end it tends to burn through, having said that i dont use a coin i use mild steel plate cut to size, note yours is an auto, you will lose some economy generally when you blank the egr, on the upsside you gain power and a cleaner running engine!!

on the transit, 10p fitted a treat. on the v6 i managed to over tighten and break the cast

what ever fits without mods is best

what engine does like warm air?

No concerns then about the reduced (non existance) of air
getting into the manifold.  I assume there has to be some other source of air for the fuel to burn.   :-?

When I did mine, I cut down part of the old EGR pipe, hammered the end flat and folded it a little to seal the end...  On the Valve end, I cut down a piece of tin and bolted it to the body (although in hindsight, I would have done better clamping it under the old flange from the pipe).  That said, I didn't at the time have anything more suitable available at the time...

It has passed its MOT since I blanked it and the car does seem to run reasonably well since it was blanked...

Sounds like butchery to a very high standard, I wonder why you have Psycho in your name.

Your all a bunch of pikeys!!!!lol,blanking egr valves off!!!while it's off,just clean it and spray some lube in it to get it working properly!it only takes 20mins if you take your time and it's sorted! :-?

shut yer face else wer cum round an burn ya parts list down.

Been there, done that,     So what's a 'pikey' ?? It better be nice or I'll be round there as well, with Tapper888.

Pikey/gippo/bodger/tinker.   We've all been there tho!!!the best I've done on my old metro was fibreglassing the sump.......it was only supposed to get me home.....3months later and still no leaks!!!!!

If it's the same setup as the petrol engine, you'll have an Idle control valve located seperately from the EGR that automatically regulates air intake at idle. As soon as you apply the throttle, the butterflies within the throttle body open.. allowing direct air intake to the manifold  I don't believe there is any relationship between the EGR and the air intake needed to burn the fuel. To my knowledge you could in theory, completely discard an EGR valve assembly.. block of the manifold intake port for it, and wouldn't reduce any air needed to run the engine.. Temporarily block it... if the engine starts then my theory is right  alternatively just ask any OOF member with a TD if you have a seperate ICV? if you do, then the EGR can be dealt with however you like

LOL the turbo shoves more than enough air into the inlet!!!

Thanks guys, that answers my question.      Just trying to understand how this whole thing works. I had wrongly assumed the torbo'd air was also going through the main body of the EGR at inlet 5 in the diagram.
