egr?

[meek.tv]

is this where the egr blanking plate would go if I was to buy one?


it seems as if there are two thin metal gaskets attached but both seem to be slipping and hanging at a funny angle.
what are peoples experience with the blanking plates? Is it worth doing? Is there any point doing it without cleaning out the whole inlet manifold etc?
I have limited skills and knowledge in this dept. but removing the inlet manifold looks a bit beyond me

It's better to block both ends of that pipe, but the end in the photo is the easiest. The gaskets you can see in the joint are designed to be slightly oversized and that shape, so that's totally normal. Allans in Plymouth do a good set of blanking plates that are properly machined to size. My previous Bongo was already blanked so I can't comment whether it made any difference.

I've blanked off both ends and taken the pipe off completely.
makes it so much easier to get at the glowplugs and bits on that side of the engine.



Its worth cleaning the manifold the manifold while you're at it, usually full of gunge.

cheers, I'll get around to it at some point I'm sure

Just be very careful!

Why? Well ...whilst changing mine, some of the small rubber hoses going to various solenoids broke ( all where hard / brittle although they were made out of solid plastic! ) as they are in the way so, I decided to replace all of them with silicone hose ( good quality can be purchased very cheap off eBay ) ....dremel cutting was required on a few but took my time and they have all been changed. Do not try to 'pull' the old hoses off the solenoids as you may well snap the plastic nipple then the solenoid is u/s! I physically removed all the solenoids to do this but again, bit of advice ....take some good photos 1st of the layout of the old hoses / solenoids as you will never remember where they all went once you have removed the old hoses. I did 1 at a time to avoid problems .....worth doing though!

I blanked mine off today but did several other things as well - the bongo felt a little fitter following but nothing ground breaking.
I would guess cleaning out the inlet manifold might help and with the EGR blanked off, it's less likely to get gunked up again.

but it may run a little hotter now so keep an eye on it.

and the engine oil may be changed to a different spec for non egr diesel engines, as it wont need the soot grabbing extras that egr oils have in them.

Thanks for the info
I have 3 engine coolant sensors
-A low coolant alarm
-A temperature sensor on the engine
-The outside of my left leg as it touches the centre console.

are they hard hoses as the are being used in a suck situation

and soft ones might collapse and close uo

When working on Bongo's near to the egr and the solenoids, especially when changing glowplugs I tend to always need to replace the vacuum hoses as one always "snaps".
I use the neoprene vacuum hose by Pearl.... PVH01C. Most Trade counters stock it (Bennetts) or you can get it online too. I like it because it's firm yet pliable.... Be careful removing old hose..... I have found too, a one way windscreen washer valve which I use on line which replaces the green jobby... you know the £45 one.... this one works fine and at 75p... a bargain

Hello Ady I guess that's a possibility.

It may be reassuring to know that Allan has been fitting and selling the Bongo EGR blanking plates for more than 5 years now, with no problems found.
He first fitted them to a bongo he owned, to test the plates and their effect.
He ran it for a year (and many miles) before he started to sell the blanking plates. The Bongo still has the plates fitted.

The only ocassional problem so far, is not the EGR, but the green valve that's near it. It can be knocked and broken when working on anything in that area. But the majority of people don't knock it, and if they do, there's an easy fix for it using a one way valve, as Mike says above. (Allan does also have valves, if people can get them anywhere).

Blissless ignorance.
What is EGR?

Mmmmm....interesting thought, didn't think of that! They were just so brittle ( snapped very very easily! ) that I assumed they had 'hardened up' so changed them all.

Anyone enlighten me please as to the make up of the small hoses all around the EGR solenoid area? Are they originally a hard plastic / rubber hose and have I possibly done wrong changing them for silicone hoses?

Thanks

Hi Jem
EGR stands for Extremely Greasy Rag...
Actually, Exhaust Gas Recirculation...part of the Emission Control system...you'll find this explains it:

I finally got around to ordering and having a go at fitting the blanking plates.
I started at the easy end (towards the front) and swapped the gasket over for a blanking plate with no problems but the one at the back looks a lot more fiddley and with all the talk of bits flying off and breaking I left well alone.
Will it still work blanked at only the end that did?
I was suprised at how much crud seemed to be attached tot he gasket alone, I''d hate to think what the inside of the inlet manifold looks like :S
