Wow! Somethings not right there. Mines around 13-15litres and thats flogging it.

If you have a boost gauge I wouldn't block the egr as your boost will be all over the shop and you be constantly looking at your gauge. Worse than pre egr. If you don't have a gauge then you won't...

Hey Bindi. the Scangauge wont show EGT's because there is no factory fitted pyrometer on the Patrols, same as for the oil temp gauge. Technically your EGT's should be lower when blocking the EGR as...

After more searching of forums and googling I am still a bit bamboozled.

I think for starters I'll fit a scangauge2 and see what is happening with turbo boost etc before any mods. Then I'll do an...

thanks, and just looking at the scan gauge 2 and the spec states that when connected to the obd2 port that it provides a monitor of turbo boost levels. It would be great if could also monitor EGR...

G'day Bindi. I'll tell you what I know and what I've done from my experience, as I've been in the exact position as you after I bought my CRD.
First thing I searched was, do CRD's need a EGR block....

Mudski,

Thanks heaps.......
EGR blocked, Needle and Dawes installed. Eventually managed to get the piping correct with your PM.
Max boost i am getting now is 16PSI, and temps look great. Need to...

The simple answer is that while all modern diesels do operate with some level EGR, the ZD30 uses very high levels. Peugot do have their problems also as do many other manufacturers, but the Nissan...

All I can tell you mate, is that the EGR system was introduced as an environmental thing.
Just about every modern engine is fitted with one, even the petrol motors.
Time will only tell if these...

Of course being a Nissan forum, it is forbidden to mention other brands that may or may not have better designs...

I would be interested in the answer too from someone with more authorita than...

Question; After reading all the negative comments on here regarding EGR, I find I must ask the question, are all DIESEL powered vehicles today fitted with this system ?
I KNOW, my 2006 ST I 3 liter...

You need to loosen the two bolts to the manifold and just check that it is blocked, there is a plate that looks like a blocking plate, but it's not!!
Cheers, the ferret.

When you block the EGR, the boost isn’t raised by the ECU, but it increases because the intake air pressure can’t escape out through the exhaust any longer and all the exhaust gasses are being used...
