blanking off the egr valve

[steven240374]

Hi i have bought an egr blanking plate and wondered if its safe to use on a car i use everyday i should have asked before i bought it but thats me all over, jump then think lol.

[Robsey]

Yes it is perfectly safe to fit the blanking plate, as long as you also fit the gasket.

The EGR is allegedly only used to meet certain emissions criteria before the vehicle leaves the factory.
It is not required to be in place for any tests (MOT etc), once it has left the factory.

When removing your EGR, be careful not to knock any accumulated soot into the inlet manifold.

I assume it is a Mk3 Astra C16NZ blanking plate, as I believe there is no number on EPC for a Cavalier C18NZ item - but before you panic, it does fit the C18NZ manifold.

My girlfiends corsa 1.4 8v wasnt running too well, jerking allot and holding back allot.

So i thought i'd try blobking off the egr valve, i used a dr pepper can, cut it the right shape and stuck sum sealant on there too. Stuck it on and what a differance!

It now drives perfect, no jerking, plenty more power and doesn't hold back at all.

Get it done!

Anything particularly special about Dr Pepper cans, or will any do??

Never heard any bad comments after others have done this, so yes - go for it!!

[steven240374]

Hi typical the one i bought doesnt fit so i am currently drinking a can of dr pepper to make my own lol

[steven240374]

Job done made it out of some nice shiney metal feels more responsive now

[Robsey]

Good simple job.

I thought about this a while, and wondered to my self,
"A tin can is made from a very thin gauge metal, surely the thin metal would deform, and not sit flat down, apart from where it is held by the bolt heads"

Did you not find this to be the case?
I presume not, looking at your comments.

Hmmm, approx £8 for a blanking plate, or 65p for a can of Dr Pepper...
I suddenly feel thirsty for a can of cherry coke

[Envoy CDX]

Robsey, depends if hes running a 1.8 or 2litre. If its a 16v 2litre the EGR is a different design and the coke can works well, however you could get some corking gasket and use that too

It's just our c18nz engines that require a steel plate for blanking. Speaking of which, have you made yours yet?

Robsey,

Now, you know me Gary,

I take forever to do anything..
Took me 6 months to fix a running fault,
Took 3 years to wash the car,

I will get round to this some time soon-ish.
Will have to change my fuel filter too - it hasn't been done since 1995 (I think it is a K&N unit fitted by the previous owner).
Personally I didn't know K&N did them, but it is stamped on the casing.

I keep finding new things to do, because the old girl has been neglected for the last 194,000 miles... (all my fault).

[steven240374]

I helped a friend of mine change his front wing on his pug so i used a bit of his old wing,i couldnt get the can to stay flat enough, i just run a 1.8 ls so not sure of engine code though

[Robsey]

It is more than like a single point injection unit, referred to as a C18NZ.

It is Vauxhall's "Economy" engine, but only gives about 89 bhp.

Here is my rather mucky engine, which is also a C18NZ.
Yours will be 1000 times cleaner than this!!

I'm starting too
Aye, theres a plate sold by Vauxhall for the task Steve, Full kit comes to less than £10 with gasket and new (slightly shorter bolts).

Why? mine isn't any cleaner

[Robsey]

I take it then, you didn't look at my embarrassingly oily cam housing.

It isn't leaking now, but it is still caked in oil and dirt.

The rest is quite clean-ish apart from an oil leak at the bottom of my bell housing - leaking rear crank seal.

And if you look at the cam-belt change How 2 that I did, then there is oil spattered on the wishbones / subframe.

The parts for the C16NZ2 and C18NZ EGR Blanking modification are as follows: -

Blanking Plate = 92 065 430

Gasket = 92 061 674

Shorter bolts (2x) =11 051 927 code is each.

Price all in, is in the region of approx £8.60.

Subframe won't rot then will it

[Robsey]

That's a good thought...now then....Hmmmmm

I'm just thinking of putting in some extra plumbing to feed the stray oil into my sills.

The car would be fine then

Pop sill covers off, nice big funnel, feed it trough the slits on the inner sill and drive up a hill

I only used a dr pepper can as thats all i had in my hand at the time lol.

And lets face it if it blows again you can just get another can.

Looking back at Gary's comments, I assume then you don't have a C18NZ or C16NZ2. As he says, the EGR flange is a different shape.

he he, iv gone one better, iv got 2 egr valves so when one gets coked up i swap them over & clean up the one iv taken off ready to swap over next time....works every time & as it happens iv just swapped it over today

Well if that is the case, then all you need to do is just clean the thing, and refit it, when running goes a bit cack.

I assume you do change the gasket though, or is it not damaged, when you remove the valve.?

Having a spare though, does mean you can clean the clogged one at your leisure.
