After looking how the last owner has blanked the egr and removed all the pipes i have noticed at the back under the EGR here the bottom pipe went to is open?

is it a breather? or for the gasses? is it ok and what would people advise on doing?

Shes in for two new tyres and abit of tracking tomorrow aswel!

Paul

that's definitely not a breather, its part of the EGR system - ive blanked mine, left the pipes in place, and that part you have open is blanked.


I'm no expert, but I'd say it needs blanking!!

Thanks Clivvy, when i blanked my m/w i left the pipes in place. the ebay search is on! or an diy job. im not sure if it ejects gasses or sucks gasses.

that looks like the outlet end of the egr cooler, think of it like a heat exchanger.
if the turbo has a thick blank on the manifold the other pipe is probably off also corregated tube 20-30mm in a 90 bend
its connected in the cooling circuit of the engine coolant and comes off the thermostat housing and probably joins back on just above the turbo manifold egr port.
garage just removed mine while he was in there doing some big jobs and i supplied some 16mm silicone blank ends

it can be left on indefinately but i was worried i was loosing too much heat in reverse and losing mpg from extended coolant heat up time, but ive not noticed much difference now its gone, biggest difference came with new thermostat
even logged and graphed before and after on journy to work

the only risk may be if tubes inside fracture and you loose coolant , but risk is lower now as its not getting hot with egr gas anymore.

arrgghhh!! my is blanked by the turbo/manifold, i know the little 90angle piep you mean, so is yours under the egr got the silicone cap on like above the turbo?

mine is now removed completely off car(egr cooler heat exchanger chamber that is) and then the outlet on the thermostat housing(picture is upside down but if you see where temp sensor is its opposite side) has a silicone cap that was originally feeding to the cooler and then another cap on that rail aabove turbo.
i drove for a couple of years as yoiurs is , just blanked at turbo manifold and at inlet manifold and had no issues.
its only cause garage was doing cambelts,waterpump ,thermostat and inlet manifold and already breaking into coolant system i asked them to whip it off.

ok, so i need to put a cap on the cooler (thats what is open on mine?) where did you get the silicone cap from?.

ok thank you

Paul

take alook at this ebay ad, i take it the big tank thing is the cooler which stands up. i need to blank the top.

not really, you can leave it as it is if its got blanks at manifold and egr valve.
the open pipe is now redundant but wont do any harm still being open, the engine coolantis sealed inside the cooler as the egr gas passes through small bore pipes inside.
there will be nothing coming out or going into that open end.
when i get chance ill post some better pics of the inside of the cooler, to help explain.

Spot on thanks Sussexa,

just got her back from getting new tryes and tracking! nice to go in a straight line!

many thanks for the help

Paul

heres some better pics for you to see whats in there






as said at the minute you have a sealed heat exchanger with engine coolant passing around those tubes inside, the egr gas is no longer passing through those tubes so if open both sides its open to ambient engine bay air temperature.
I can confirm its not really worth the cost or effort to remove the cooler ,as far as expecting quicker warm up times.

Great, thanks for the pictures. it can stay on if its a pain in the bum!

nice one SussexA, that's clearly explained things a lot, ive learned something, and this is appreciated, thank you!
