What i did for the PCV Re-Route is use a 3/4 by 1/2" 90* copper fitting and 6' of 3/4" heater hose. I ran the hose by the frame rail and cut it off at an angle by the ABS in-between the doors.

Kade ,that looks good

mine was setup just like yours,but it would constantly drip a lil bit of oil...no matter how tight the hose clamp was

Kurt, there is some minor mods if you search through the dmax tech section
not many things in life are free and as for the PCV rerought i recomend this to anyone,next D-Max i buy it will be done as soon as i get off the lot
but its not for POWER its for cleanliness

do you have a blocker plate?

You can also get rid of your egr cooler and motor if you have a buddy that can weld, just remove all the egr mess, and where the egr motor connects to the intake, just weld covers over the holes. Install a 1/8" plate over where you have installed the egr blocker plate and put in a section of heater hose where the egr cooler was.......shouldnt cost you but $20.00 in parts for this one. you got a homemade egr delete kit.

You can also open up your turbo inlet pipe as described in this thread and plug the pcv and resonator inlets

Larry i already done the fuel rail fitting. I will look more into the re route and the egr delete. Simon the egr is blocked its got the ppe blocker plate. Now all i got to do is the cp3 mod and a cheetah charger.

the lly and new routes the PCV (positive crankcase ventialation) back into the intake.. good for emission

bad thing is it can lead to a runaway condition on a diesel and the is VERY bad

Not sure i'm following you Adam, are you saying the way the factory has it will create a runaway condition or when we re-route it the runaway condition can happen

say your crankcase floods with fuel. only opening is either gasket or the PCV.

if the PCV is routed like a gasser back into the intake were is the fuel going to go? back into the intake and the engine will burn it.

BTW when mine flooded i got fuel oil and coolant all under the truck..

PCV in a diesel is bad because it pumps oil into the intake, which is what can cause the runaway condition, aka you're pumping oil that will burn as fuel into the motor in an uncontrolled fashion.

Ditch the pcv and the issue goes away, as does coating your turbo, pipes, and IC with a layer of oil.
