By Bypassing the piston rings!

yeah, I get that part, so it looks to be a cheap fix/life extender for a tired engine. there was a couple of blokes with new-ish trucks looking at the bypass option,
why bother with a healthy engine? if, no real change in power/fuel consumption?
mate, I'm not a mechanic but I like my patrol just like any other bloke on this forum and I want my old 2.8 to keep kicking for a while longer so I will probs do this bypass option, but for a newish healthy truck I probs wouldn't bother
Mate, to be honest, If I bought a brand new nissan, the egr would be blocked before I took it out of the driveway, have you ever had a look inside the inlet manifold when EGR has not been blocked??
Well have a gander at the below pic>

Back in the old days, we would "port and pollish'' the inlet and exhaust manifolds, this was very painstaking and took hours to do.
It involved sanding and pollishing and buffing to get the smoothest finish.
Even the crankshaft would be removed and all of the sand casting marks would be pollished off, leaving a mirror like surface.
This was to reduce any friction between the sump oil and the crank.
for example, we had a Ford 10, 4 cylinder side valve motor pulling 7000 rpm.
So, an inlet manifold packed with 5mm of carbon/oil/ soot etc, is only going to cause over heating, and when the MAF get's the message after being coated with oily mist and dust, and then relaying the info to the ECU, you will end up over fueling and a hole in the piston due to high temps
The people who invented the EGR don't give a rats about how long your engine will last, all they care about is the environment.
So I block the EGR and grow ROSES!! not.

yep, got it. cheers Ferret.
by the sounds of this.... i need to block this up right away
ok guys this has been a great thread but let me get this right....
i have a CRD 3lt 08 gu...
1. get egt and boost gauges installed. ( would love some ideas on where to put said gauges )
2. mount egr plate. ( will be getting plate from ferret.)
3. Dawes valve to adjust boost.
4. get scan gauge to get rid of error code and to help monitor engine.
sounds easy.. ( time for piggy bank to meet hammer....)
am thinking also about a boost and egt gauge, have you seen the gauge mounting panels that replace the pillar trim on the drivers side, they are on ebay?
I'm going to pull the cover off mine next week to have a look, pretty sure it will look similar.
