EGR help required MK5 transit

[Tony-1976]

Hi forum,

anyone know if my transit mk5 actually has an egr pipe worth blanking off?

what difference will it make to the general running of the van?

picture attached.

That pipe from the air intake to the manifold is the egr pipe blank that off and it will run better with more power

If you unbolt it at the manifold end, get it hot before you start and use a six point socket.
For some reason they are imperial size bolt heads (3/8" from memory).
Be patient and very careful taking them out, if they snap off it's a bit of a pain in the arse.
You can either make a blank using the gasket as a template or buy one from ebay for a few quid

Hi guys thanks for the info so far.

Should I blank both ends??

I have circled on the pic what I mean.

No just the end at the manifold

You need to be very careful with the bolts at the manifold

Your engine looks for engine with Bosch fuel system - is it?
In this fully mechanical system EGR has not position sensor. EGR is controlled by vacu actuator. If you blind vacu pipe between EGR actuator and inlet manifold, EGR will stay still closed. That this is the easiest way to blind EGR in 2,5D/Bosch. Ten minutes of work.
In 2,5TD/Lucas Epic EGR has position sensor - this method is wrong.

As above, don't struggle with the pipe, I simply disconnected the control rod, and cable tied the butterfly on the air intake, in the wide open position

Yes, it is effective way for EGR deactivation - but... easily visible.
If you insert metal ball into vacu pipe between inlet pipe and EGR actuator, no one will know that EGR is permanently closed.

Hi Guys,

im lost a little!!

do I need to find a metal ball which will fit into the egr metal pipe?

No, Heaven forbid...
EGR is controlled by vacu from inlet pipe, membrane actuator openes EGR with this. On idle, throttle in inlet pipe is closed, so vacu in this pipe is biggest and EGR is opened.
You should to blind thin rubber vacu pipe between inlet pipe and actuator. In this case membrane actuator doesn't work and EGR is still closed. Vacu rubber diameter is inside about 3-4mmm, so you need small ball or anythink similar, which will block vacu to actuator.

Altransit wrote about similar method - block throttle in wide open position, and that will make miss vacu - EGR is also still closed.

So finally got out to the van again today and in closer inspection it looks like someone has done some sort of bodge job already.
I will attach some pics so you guys can see what I mean. A pipe has been cut off and blanked off with a bit could this be the famous egr blanking off?! If so the bolt is loose as anything I will put a jubilee clip on it and keep it in place.

The egr pipe is the metal one in your first two pics at the back, it comes off the top of the exhaust manifold and connects to the inlet manifold.

Red arrow on photo below shows vacu pipe which should be blank. If this pipe is opened, dirty air is sucked into inlet manifold. Cuted pipe with screw can be opened. This screw is needless.
But: blanking EGR is not legal and in this method (with cuted pipe) you can immediately see that EGR is blank (doesn't work). I wrote to put into vacu pipe metal ball (or anything like that) and later connect pipe back. No one gets to see this. Best place - place where pipe is cuted now - between EGR spigot and plastic elbow.

EGR blanking is not illegal UK and is not an MOT fail either.
