diesel egr issue
 

Evening all,

I have a slight problem with the EGR on my diesel ZT. Took the bypass off the other day to find the end part of the exhaust gas pipe (the one which gets blanked off by the EGR bypass) has broken off! The end bit which gets clamped to the egr bypass.

Anyone know if that pipe is replaceable and how far back it goes or where the closest joint is? Looking on rimmer bros it looks this this is the part I would need? https://rimmerbros.com/Item--i-WAP10...SABEgLRYvD_BwE

Cheers
Rick :)

Hi Rick
That part is a bit expensive mate, I could supply you with another for a auto for £18 if that helps mate

Take it to a local body shop and ask them to braze it back on

Just blank it off at the manifold end and be done with it Rick.

I have seen a few of these break especially on automatics when a bypass has been fitted.

Hi Andy.
I have read that also the Auto ones seem to fail after bypass, don't they have a water cooler attached though ? therefore if blanked off at manifold would this not effect said cooler, if not could a manual one be fitted ?

Taking mine off had no detrimental effect and there was no water cooling system... both autos on 00 , 03 and 04 plates...

I thought the heater/cooler, from the exhaust on an Auto as a drain screw on top as well, see photo's below.

Heater/cooler.

This also shows an hose fitted to the other part of the pipe work.

The same part can be seen with the manifold off.

As opposed to the manual exhaust pipes here below.

We are on about blanking it off at the back of this exhaust pipe, not removing the heater/cooler right?

I never removed past the initial flexi... the kits i had just capped off at the inlet just before the cooling and deleted the EGR valve and vacuum valve which was also capped.

Rik if it is for your Auto then I would do as klarzy says get it brazed and fit it back, then maybe do as Andy said blank it off at the rear, you need to make sure that the MOT man can not see it as been tampered with.

Cheers Mick, are the auto vs manual ones the same? My ZT is a manual.


Thanks for all the alternative suggestions all :) If i were to blank it off further back on my ZT what could I use to blank it off?

Yep, leave it all in place and put a piece of 2mm thick aluminium between the egr pipe and the exhaust manifold.

Use the gasket as a template and no one will ever know!

Make sure the flexi is connected to something solid at each end.
Ie, don’t blank and leave unconnected to the egr valve.
The result would be the flexi elongates and rupture.
How do I know this?🤔🤔🤔

Trikey, What’s the best way to access the exhaust manifold to do this?
From below?
Had a look from below a few months back, and access looked like I’d need double jointed flexi fingers to do this.🙄

I did mine from above, long 3/8 extension bars and yes, double jointed fingers help.

it's best to blank the manifold, think you have to take the battery / battery plate off for easy access. This is the one like I used:
