Title: EGR valve blanking plate
Post by: MartinP on 19 December 2006, 22:31:19
I now have 1 dozen EGR valve blanking plates, made from 3mm mild steel as photo.

Anyone interested in one of these let me know. After I have posted the first one I may ask for postage to cover my costs.

OK mate but why would you need one?

Because some people remove this valve and blank the manifold off (not the valve as in the picture ::))

While I have never looked into this, I am aware that several people have cut up pop cans and various other tin recepticles to make a blanking plate.

As I have access to a laser cutter, I got the programmer to copy a gaskget I had spare, thus I have a few to dish out.

There is a disscussion on this subject here,

Worthwhile mod.....it does two things:

1) Improves throttle response slightly (no exhaust gases can no get into the system and dilute the fuel/air mix)

2) You never have to worry about a leaking EGR valve again.....

Just a quick one.....are the existing torx bolts long enough to accomodate the blank?

Does any one know if the physical dimensions of a V6 Omega's EGR is the same as that of a 16v 1.6 Astra G? Is an Astra 16v 1.6 basically the same as a 4 pot Omega?
I ask cos a certain 'tamed' Vx service manager has told my wife's Astra that it doesn't now have an EGR valve and it's now been unplugged for the last year or so.

I don't know if its similar to your wife Astra but Vx were modifying a lot of there small 4 pots up to 1800 cc to do away with the egr valve. I beleive there was even a technical bulletin on it, telling the dealers how to do it and reflash ecu with tech 2 to do away with egr software but like i say i don't know if it applies to the 2 ltr up engines :)

No, currently older Omega engines do not have option to remove egr from ecu, hence blanking trick....

So, if the valve is removed and blanked, do you get any fault codes/lights.
also will the car still get through the MOT?

Apparently no fault codes, and this is not MOT tested so no problem there either.

However, not possible on the 2.6/3.2, as they don't have a mechanical EGR valve, instead the EGR function is electronically controlled by the ECU. AFAIK the 2,2 still has a mechanical EGR though.

Ok, so PM is definitely working. All who would llike these plates PM your address and I'll bang them out asap.

I can get as many of these as is needed, as the program is saved at work, so there's no panic

Sorry issunaz, I'm in IT... you saved it on a computer ??? Now I'm worried....  ;D

Yes they are long enough as the plate is half the thickness of the valve flange. What I don't know is if the bolts are too long!

Are the holes in the maifold "blind", and what depth are they?

Or put a thick washeror two on the bolt.

I'd love one of these, but unfortunately that type won't fit my engine :(

Any chance of making one for the newer style EGR that is bolted on to an extension pipe thing? There are three torx bolts holding it onto the plenum. Mine is currently blanked off with an IRN-BRU can, and I'm pretty sure it's not airtight cos I've got a lumpy idle.

I don't have a picture here just now but can take one if you need it. I'm sure someone has a spare one or two of these lying around :)

Cheers!

You know how the saying goes;

Remember that you will need to keep the EGR valve to prevent error codes appearing...so it would be best to sandwich the plate between the EGR valve and the mounting flange.

as long as it can be cut out of flat steel,

Let me have a dimensioned sketch and it shouldn't be to hard.

may have been better with 1.5mm  :-/

Cool, cheers. Does anyone have one of these type of EGRs lying around off the car? It would be pretty easy to sketch that way, unfortunately I can't remove mine cos one of the bottom bolts won't budge - bent the teeth on a Torx socket trying! The ones on the manifold are no bother, hence the IRN-BRU can ;)

Just thinking, maybe I can just get a gasket to use as the outline and either trace that or send you one.

Gasket is good, thats how I did mine  :)

I hate sounding like a thicky but where would the EGR valve be on a 2litre engine ?

OK I was planning on buying a replacement gasket for mine to try and cure the poor idle so I'll pick up two instead and send you one. Probably next week I expect... will keep you posted.

Yes, you will get EML and stored code if egr unplugged electrically.

hey, sorry for bringing up an old post but will this fit the 4 pot (X20XEV)? if so, do you still have any and again if so, was there a postal charge? :y ;D

Haven't got a blinking clue, someone with a knowledge of the 2.0 will be along soon.
