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!! :y

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. ;D ;D ;D :y

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, ;D ;D 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!!!!! :D ;) :D ;D ;D

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 :y 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 :y 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!!! :y

Thanks guys, that answers my question. :y :y 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. :-[
-
so what exactly happens when you floor the throttle in the TD, what happens within the EGR? does the flap completely seal and stop any exhaust gases from entering, if this is true it seems that mine must not close somtimes when i floor the throttle because i get no power at all, then i back off and then on again and the power is back , its bloody annoying

You need to check the small braided vacuum pipe that goes from the egr solenoid thingy (next to the power steering fluid bottle) to the underside of the inlet manifold this tube gets blocked, or as in my case the inner tube was split just at the union, repairing this made a temendous difference. :y
-
thanks, do you or anybody happen to have a picture of which one you mean, at the egr assembly, number 1 on your picture i have a braided hose that connects to another part of the egr assembly, i will have a look for the other hose you mean, so its from the powersteering area to the underside of the inlet manifold, how long is this hose, maybe that will help me to find it

I'm very confused why nobody has said this.. Point 5 is the only way air is going in to your engine! Put a blanking plate where you have the red line and your engine will not run as no air can get in.
-
I re-connected mine as the cruise control was all over the place on the M-way.
Also make sure you don't kink the 2 vac pipes that runs from the manifold to the solinoid below the alarm switch on the PAS resevoir.
Im battling at the moment to solve the code 96 egr valve out of range ive cleaned everything and changed egr.
And we call pikeys yannies in Falkirk ;) :y

Not that one but if you follow that you will come to the other one that goes onto a union sticking down from the underside of the manifold about mid point. that's where it blocks or splits.

That's what I've been thinking. I went out and looked at it again and came to that conclusion.
So a 1 pence piece filed slightly made a perfect plug for the exhaust gas inlet.

Then again, how can you explain Omegatoy's post who has both orifices blanked. [smiley=huh.gif]

AAAARRRGGGGHHHH sorry guys i didnt look at the picture,
no no no i block both ends of the egr pipe!!! one at the inlet plate and one at the exhaust manifold, lol sorry for the confusion i tend to just assume everyone knows thier own engines!! :'(

Your conscience will let you know when you've been punished enough. ;D ;D ;D

sorry here too kneepad. didn't know that the egr on the TD is a combined unit.. on the petrol engine you can blank it, remove it or even blow it up inside a caravan & it won't affect your intake ;D I've looked at the diagram properly and you are right to only block No.6 exhaust gas inlet :y I now understand the importance of the turbo on a diesel, if the intake for combustion is so small :o well done for sorting it out, you can drive with peace of mind knowing you've just got rid of the nasty stuff :y

Right you go to the corner as well. ;D
No, the more I looked at it the more obvious it became that it had to be a different setup from yours. I still appreciate everyones input. We can all learn from each other's comments.
