Title: EGR delete worth it?
Post by: mrapoc on 04 January 2012, 15:01: Hello

Firstly, are they worth it in gains?

Also what about MOT emissions test (UK)?

Lastly, insurance companies...they probably add an extra premium?

Would I be better off blocking the end of the EGR?

Thanks!! :laugh:

When you remove it you can get rid of a lot of vacuum hoses which makes your engine look tidier...that's about it I think :undecided:

6 of one, half a dozen of another.

As the EGR is vomiting your already burnt exhaust gases back into the inlet tract deleting it is unlikely to be a bad thing - they're there to improve emissions.

The big thing, as alluded to by Scarr is that it stops sh*t going back through your inlet manifold. When you go to delete your EGR you will probably find it's all furred up with soot. Deleting this will have a positive impact!

Post by: mrapoc on 04 January 2012, 19:50: I could always clean and keep the EGR intact and block off the vac lines to it?

That way insurance wont be any difference, it can be reversed for MOT and theres no crap going back in?

In short: don't do it.

+1.

Either get rid totally or leave it as.

Also passed MOT's without issue (even with a de-cat) because derv's are only smoke tested. Older ones like the PD130 anyway.

Post by: mrapoc on 05 January 2012, 16:29: Are there any downsides? Engine run-off sounds serious!

What have you done with the vacuum leads? I've got my EGR off today to clean and its quite a ballache! I don't fancy doing it again really lol

Post by: olliemk3 on 07 January 2012, 19:37: egr is a crap system, im an iveco technician and there vans are always needing egr valves because they coke up, youd be surprised on how much s**te builds up due to egr, its well worth getting rid of, on some vehicles there a nightmare to change when they cease to work, ive been in a few vehicles before egr delete and after and it does make a difference, better off without

Post by: mrapoc on 08 January 2012, 21:00: I'm guessing they all perform the same and the same to fit. Which is the best to buy/fit and cheapest?

My main concern is insurance companies...Anybody have any knowledge on the matter?
