EGR stuff

[Mont]

Hi All
Ive just got my new rig Patrol Wagon 2004 3.0l !!! Stoked im sure this issue has been discussed many times before but apparently the catch can is the go to keep exhaust gasses away from rear cylinder (i want to do everything possible to avoid the grenade!!) although by 2004 hopefully these issues were addressed somewhat. Also boost gauge ? EGT gauges ? also intercooler seems a bit loose im guessing the rubber bushes just need replacing but any other issues around this area?

O.k. Sorry for the late reply. Missed this one. A catch can is used to filter the engine crankcase vapours. There is a hose from the top of the motor to the intake hose just before the turbo. The catch can goes "inline" on this hose. The EGR block. There is a plate that goes on the cast EGR pipe on the intake manifold side which blocks the exhaust gases from re-entering your intake.
But before you do this mod I highly advise you instal a dawes and needle valve first. Blocking the EGR will result in slightly higher EGT's and make your boost levels go crazy.
Blocking the EGR is the last thing you should do on the Mod's list.

G'day Monty,Muddy and all,
Reckon I've seen this kweschun a coupla times before. Could that be??
At the top of the forum page there are a few 'highlit' threads which are there because they're so fundamental to owners of 'trolls.
Someone, somewhere, somewhen with lots more knowledge than me must surely have written/answered this type of thread before.
I think it would be appropriate to include a comprehensive list of mods. in order of priority and put it firmly, permanently up there. Love to have my name on it but that's not a goer, knowledgewise.
Thoughts everyone
Col

Hey Col. What the hell is a kweschun?
In order for these mods on a 3Ltr Patrol I would do it in this order...

1. Instal Boost gauge. This has to be installed first as you need to pick up boost pressure and then measure boost pressure to set the Dawes.
2. Instal EGT gauge
3. Instal Dawes and needle valve and set your max boost on the dawes
4. Set the needle valve at 10psi @100k's. (starting point)
5. Instal EGR plate (You may need to re adjust the Dawes after this)
6. Instal Catch can
7. Have beer.

Err. Nevermind about my question on your, kweschun. I got it.

All sounds easy when you list it like that !! Best place and brand of boost gauge EGT probably get what you pay for ?

Better brands are up to you, autometer, autron to name a couple, plenty of others out there as well depending on your budget can spend 100 each to hundreds each hahaha, always pays to shop around once you decide on the brand you like.


Cheers,
Eric.

Cheers Eric and mudski will look around gather my thoughts and parts for the mods to be done hopefully in the near future

Where is the bet location to mount the extra gauges saw a picture of the Gauges midway up the A pillar is that an accepted spot ?

[mudski]

The most popular spot for two gauges in on the A pillar. I have a single 2 in 1 McNally gauge and this sits in a gauge cup in between the speedo and tacho.

I'd put catch can higher up on the list not the last. I'd also not bother with Dawes valve without doing needle valve at the same time, you gotta take turbo control away from ECU.
Intercooler is probably cracked already and leaking, any dark patches spreading about the fins near the end tanks? Don't forget that glow plugs timer mod should be high on the list too.
The ridiculous post glow time Nissan has set (5 mins) leads to all sort of problems.
