Title: Blanking the EGR Valve on the V6 (Easy Way)
Post by: PaulW on 06 March 2009, 04:35:00
This only applies to Pre-Facelift V6 Engines (and very early Facelift Engines) prior to any of the DriveByWire setups

As a few people have said on here, blanking off the Exhaust Gas Recirculation Valve on the V6 can sometimes improve Idle, and in general, help relieve a few other problems which may spring up.

Now the usual way is to get a tincan and "Cut" a template to blank it, however, Vauxhall do actually supply a 'Blanking Plate' which will fit!  It's not listed on the Omega section of the EPC, and is only listed on other vehicles, but it will fit.

So, if you want to blank your EGR valve, you need to order the following parts:

90467547 - GASKET, EXHAUST GAS RECIRCULATION VALVE

12554606 - COVER, VALVE, EXHAUST GAS RECIRCULATION
(http://i130.photobucket.com/albums/p266/PaulW21781/My%20Cars/Omega%20Elite/New%20Engine%20-%20Z32SE/eb90bdc2.jpg)

Ensure the Engine is COLD

1) Unplug and Unbolt the EGR which is on the left hand side of the engine.

2) Clean any existing gasket or muck which may be left.

3) Fit the gasket and seal plate.  Place the gasket onto the EGR mounting bracket/pipe (which comes from the exhaust manifold & goes to the inlet), then place the sealing plate onto the gasket.

4) Position the EGR valve ontop of the sealing plate in the same position it was previously, put the bolts in and tighten them up.

5) Re-attach the plug to the EGR valve.

How on earth did you find that and how much was it?

Lol, I did know about this one as its a TIS mod for certain Astra engines etc.

Trouble is, it costs money!  ;D ;D

I much prefer the drinking a can of beer while un doing the bolts, finishing the beer, cutting it out and then opening a fresh beer to do it all up again.  Then have another beer to celebrate followed by a nap.  ;)

Let me add some cold water to the hot soup ;D

when the engine is starting to be hot  and EGR tries to open up from time to time it will pay with idle somehow :P

waiting for Marks DTM to break my head

Nope and for 2 reasons

1) EGR does not operate at all on idle or WOT.

2) The idle control loop is independent of everything but temperature and external loads requests (e.g. aircon).

Thanks for the lesson :y

£4.65 + VAT (Retail) for the blanking plate, and as Pete says, I'm a student bum with far too much time on my hands  ;D
