Removing/Destroying DHY EGR piping - silverzx - 09-01-2012 My EGR plug has been disconnected a while but I'd like to do something with the actual pipe so that if and when I swap to my non EGR Xantia manifold I don't have to mess about changing the EGR exhaust manifold. I think I remember reading somewhere that it isn't that strong and that you can squish it closed with some pliers and then put sealant over either end? Does anyone have any simple methods which can be done with everyday tools (e.g. not a welder)? Many thanks! Re: Removing/Destroying DHY EGR piping - mark_airey - 09-01-2012 take the valve out of the exhaust manifold, weld it shut and bolt back into place, once you have changed the inlet manifold remove the pipe from the valve, job done ![]() Re: Removing/Destroying DHY EGR piping - silverzx - 09-01-2012 mark_airey Wrote:take the valve out of the exhaust manifold, weld it shut and bolt back into place, once you have changed the inlet manifold remove the pipe from the valve, job done No welder available Mark! Re: Removing/Destroying DHY EGR piping - Ruan - 09-01-2012 Take the valve off and somehow lamper it in a high temp adhesive so it's stuck closed... Should be OK that way. If it releases it makes a horrific noise though, hissing crackling noise under boost and the cabin fills with coal. Make sure you do it well enough first time round.

I don't quite understand what you mean Ruan? And when you say take the valve off are we talking inlet end?

The 'valve' is on the exhaust manifold. The only thing on the inlet end it the hard metal tube (~1" thick) which comes from the valve on the exhaust mani.

Lol cheers Dan, I'm a bit of a spanner when it comes to anything I've not looked into before. ![]() Is it easy to get off? I'm guessing getting underneath would be the best route? Also, when I remove my inlet should I block/crush/seal/etc the 1" pipe as best as I can? Sorry if I'm testing anyones patience but it doesn't really make all that much sense to me as to how it works! Edit: http://www.youtube.com/watch?v=cRprG7nXPTk Errr. ![]() Re: Removing/Destroying DHY EGR piping - Dan! - 09-01-2012 Im too nice..... ![]() Make a bit more sense? ![]() ![]() Re: Removing/Destroying DHY EGR piping - mark_airey - 09-01-2012 The valve is held in by 2 x allen bolts and is on the top of the exhaust manifold, once the valve is sealed shut just remove the pipe from the valve after you change the manifold, otherwise you will have a big hole in your inlet manifold and it won't hold boost too well. As for how they work, basicly the valve lets exhaust gasses back into the inlet manifold (via the metal pipe) to soot up all the inlet side of things.

Wrote::dance: Its probably clearer than my description though :roll: Re: Removing/Destroying DHY EGR piping - silverzx - 09-01-2012 Na that's brilliant boys! :-) Nice one Dan! I presume this is the valve in the "closed" position. So it would be a matter of squirting a load of silicone sealant over and around it? ![]() Blue ring: area to apply sealant. Red ring: doesn't need to be blocked providing the blue ring area is sealed tight/correctly? ![]() Please correct me if I'm wrong! Thanks Dan and Mark. ![]() Re: Removing/Destroying DHY EGR piping - Dan! - 09-01-2012 Correctomundo ![]() Re: Removing/Destroying DHY EGR piping - silverzx - 09-01-2012 I would rep you if I could but we haven't got that implemented yet right? That little area I ringed with blue looks so small and also as its a flat surface so the sealant won't have much to grip to. Is this tried and tested method? I imagine the EGR shouldn't move anyway seeing as its unplugged so it shouldn't be that much of an issue? That brings me back to Ruans comment, if this did for some reason blow upon from boost then it would just be causing a major leak from the hot side of the turbo correct? Which in effect would still be drivable but would require immediate attention. Re: Removing/Destroying DHY EGR piping - mark_airey - 09-01-2012 As above, this is correct, but don't remove the metal pipe until you swap your inlet manifold as I said in my last post or you will have an epic boost leak ![]() Edit:- and I wouldn't use silicone, it needs to be heat resistant epoxy stuff if you can't weld it, also if it was to open again its after the turbo so just a massive exhaust leak and a cabin full of coal, you would know about it!! Another alternative is to make a metal plate the same size as the bottom of the valve and bolt it on in place of the valve with some instant gasket ![]() Re: Removing/Destroying DHY EGR piping - silverzx - 09-01-2012 mark_airey Wrote:As above, this is correct, but don't remove the metal pipe until you swap your inlet manifold as I said in my last post or you will have an epic boost leak I thought this black silicone stuff is supposed to be super heat resistant. I'll check the box later.. epoxy looks cheap enough though if you vouch for it then I could buy a tube! ![]() A palte would defiantly be a better solution which I suppose I could do if I got a spare EGR from a scrappy.. :think: Re: Removing/Destroying DHY EGR piping - mark_airey - 09-01-2012 I'm vouching for nothing, mine was welded ![]() Just get some steel plate, when you change your inlet manifold unbolt the egr valve and cut out a plate roughly the same size as the valve and drill 2 holes in it in the same place as the EGR and bolt into place ![]() Thinking about it my old manifold might be lying around in my workshop, I will have a look later, you can always have the plate off that if its there!
