Blocking the EGR Valve

[the ferret]

Mate, What motor you got?? I may be able to help you with some pics, doesn't sound right to me.
Cheers, the ferret.

Set aside a couple of hours to try and block off the EGR.
Took off all the peripheral bits first and located the flange.
I don't know if anyone else has encountered this, but there is a moulded metal heat shield/shroud fitted over the EGR flange on the GUIII 3.0 litre turbo
There are 4 bolts holding it place. but the bloody thing is totally jambed in between the flange and the manifold, it will need a lot more stripping down to get it out. I couldn't even get a grinder in to cut a piece out. The shroud is preventing access to the flange nuts.
So ended putting it all back.
Definitely will have another go, but will need more time.
I noticed when I took off the rubber tubes to the turbo, the insides were black and oily. Not really a good thing when it is meant to be a fresh air intake.

You’re trying to do it at the exhaust manifold! Way Too Hard….
Try blocking it at the top of the EGR pipe that goes to the inlet manifold…. Much easier and a 5 minute job.

Oily intake tubes…………. That’s why we fit a crankcase filter or Provent. All turbo diesels have oil in the intake – normal but not good. Remove the throttle body and see what a mess you’ll have in that!

Hi fellas, just thought I would add to this thread. I just put my EGR block plate in yesterday mine is an 08 crd ute & the difference was amazing, I have a scangauge & my EGTs dropped by 180 deg C from around 550c cruising to now being 380c or thereabouts which is huge.....The turbo spools up much quicker, the ute drives much easier as in does not seem to work near as hard now. The fuel has come down from 16l per hundred to 11l although I still need to go for a good long run in order to determine the real drop but for a 20km run to town that was the difference, and that has been a daily run for 3 years always getting 16l per hundred on the scangauge now shows 11 so must be something in it.
My only issue is the boost has gone from 14psi max to 19psi max however the max pressure now appears not be under load it maxes out now when just cruising at 100kph or so, a bit weird beacause if you accelerate from 100 when it has high boost the boost drops back instantly to about 12psi then when you back off to cruise again the boost comes back up to 17 or 19psi, any ideas why this happens & what I need to do to rectify it would be a great help.
The ferret told me to put in a bleed valve to bring down the boost to 14psi but I would like to hear of other people that have had this issue & how they dealt with it or if 19psi boost is ok to run with, I am no mechanic & dont know the tech stuff.
By the way if anyone needs an EGR block plate I can highly reccomend the ferret great service & good quality gear, plate is stainless steel & 30 bucks delivered why both making one for that.......

Thanks for the diagram ferret, Looking at some of the other pictures on the thread, I was totally on the wrong side.
the whole thing makes sense now.
as you said, it looks like an easy job....next weekend now.

Must say I am really enjoying this car. The more things you do on it, the better.I like to get to know all the ins and outs and quirks. makes you more confident when preparing for a trip

Cheers Mate.

Hi guys bought the ferret egr plate and the young bloke installed it yesterday, made a fair bit of difference especially in second gear, pulls really well and very happy with it, just need to clean the maf sensor to complete the first stage of setup. We now have the 3" dump and exhaust and the egr blocked and it certainly made a difference to the troll, thanks again Rod for the plate and instructions.

All good mate, glad to help.
Just heep an eye on the EGT's and max boost.
Cheers, the ferret.

do any of you fellas know anyone that has done this and noticed the cleaner oil? I do what I can to try to extend the life of my 2.8 (drop oil/filters 5k), and not flog it too hard.
The blanking plate looks to be a good idea if it keeps the recirc soot out of the engine.

um, sorry for a silly question, but how is the exhaust crud getting into the oil in the 1st place?
