@SJC - Did you remove the AC pump....? What size aux belt did you use....? Im trying to use a non AC X20XEV aux belt as I thought that was the correct size, but it's too short...? I really don't want to re-install the AC pump if I don't have to...

Go into any factor, and ask for an Aux belt for your car, emphasising it has no A/C. There are 2 different lengths, 10mm difference, based on age I believe.

Thankyou

[minifreek]

Yeah, I removed all of the AC components and used a non-AC belt

Part # 93181718 ALTERNATOR DRIVE BELT (21.36 X 1900 MM)  W/O AirCon

Belt also has 6 PK 1900 marked on it which looks like a Gates part number to me.

Also thankyou

And yes it also looks like a Gates belt code to me too....

I only use Gates belts as they are OEM Vauxhall I believe, just a little bit cheaper...

[minifreek]

It turns out that the 6PK1900 is a reference number for a Contitech drivebelt for a 1999 Vx Vectra V6 without AC, so its been reserved and I go to collect 1 later this morning

Have also ordered an EGR cheater too, so the engine bay in my Omega should be a lot emptier when it all gets put back together, once the radiator gets replaced - again....

[minifreek]

Drivebelt collected and fitted - perfick

Just waiting on the cheater and radiator now....

[Diamond Black Geezer]

So, returning back to the orginal post, really - is this an EGR cheater for another engine or have you made a hack/mod, or otherwise? Very interested in both what SJC did and you're doing with this. 

[minifreek]

Iv ordered an EGR cheater for a Z22SE which 'should' work....

Have been meaning to delete the EGR itself for many months, and also the AC pump too. Coz I had half the engine stripped with replaceing the HG's I took the chance to do some other mods whilst I had access to them

Iv also changed the headers for later type, changed the inlet cams from G to A and given the breather system some much needed cleaning too....

Hopefully the cheater works as Im expecting, if not I'll reconnect the EGR and hide it somewhere....

[Diamond Black Geezer]

Look forward to the results. Daft question, fitting a ruddy great thick plate in the EGR and you know it's worked, but as for plugging in a magic black box - how can you tell it's doing its thing. Presumably a code reader will tell?

If all goes well I can see this being a very popular mod.

I cut up a coke can to make a gasket and put a hole where the plunger is so it can move freely,  no light comes on plus the valve is still in place to look nice

No need for the thick ebay plates

[Diamond Black Geezer]

Apparently the coke cans burn through - it's directly connected to the exhaust manifold, don't forget. Don't know how long it lasted, but I did find the remains of a burnt out coke can in the EGR when I took command of the Starship Omega, which had been fitted some years before. Might last tens of thousands of miles, might last weeks not sure.

There is a GM blanking plate, and official mod, as this EGR was used on several engines, apparently. This is a fairly thick affair, presumably for reasons of heat. 

[Bojan]

The EGR valve is removed, together with connecting pipes.
So there will be no exhaust gasses.

The reason why this plate should be thick, when discarding EGR, is to have enough riggidity to 'hold' a seal (either OEM seal can be used, or some sort of sealant) between blanking plate and intake plenum.

Without me taking the piss for a change DBG 

Have you cleaned the EGR out properly and re fitted it ?

I've owned 3 v6's with egr's and never had a problem 

[Diamond Black Geezer]

Mr Gonads - Never cleaned one out, I know it's a popular mod to blank it off. Didn't know there was any particular issue with them actually requiring cleaning, though. You saying worth me giving it a clean out? Surely something that can be safely blanked wouldnt matter if it were blocked by gunk instead?

To Bojan, sorry. I agree if you discard the EGR completely, then a thick plate will be helpful, yes, and no heat - But Frostbite said "plus the valve is still in place to look nice" In this case the common mod is to undo the EGR, put in a blanking plate, then refit the EGR. In such case theres exhaust gases hitting the blanking plate, and it would ideally do to be fairly thick.

I think some of us are talking about cars with completely removed EGRs, and some about EGRS still fitted, but with blanking plates in.

It seems so

I suspect that fitting the later manifolds is the main reason to blank EGR, as unlike Corsas the V6 ones don't fail and there is no apparent difference with it working or not.


Making a plate to blank it looked like hard work to me, so I turned a plug that fits instead of the pipe from the exhaust:





That's a small piece of steel, with an appropriate step turned in each end, painted satin black(aerosol from Poundland), and retained with the original nut:





Removing the valve and mounting lug, then  hiding the cheater in the cable tray seems like a good next step to me , as the valve is really bulky for something that is no longer required.
