Which engine protection/longevity mods first?

[insect_eater]

Hi all,

I'm excitedly awaiting the arrival of my NX in late May, apparently one of the last manuals to be delivered to Australia (I'm told that the dealer code has been deleted, and manuals can't be ordered). It will be the family tourer and explorer and I plan to keep it for 10 years or more.

I'm dreaming of the normal list of bushskinz, winchbar, suspension lift, snorkel/breathers, LRA fuel tank, rhino platform, and dual battery. I've already bought 5 second hand genuine steel wheels (17s) that I hope will fit (the soccer mum thread suggest they will), to which I'll fit some A/Ts.

As it will be a keeper, I'm keen to give the engine as much chance of longevity as possible, but I'm confused as to which mod first and which combination gives best protective value .

In order of priority for engine protection/lonegity does the following make sense? What am I missing?

Fuel filter/water trap (eg. dobinsons/WW/fuelmaster)
SPV EGR controller (I'm assuming this negates the need for a blanking plate
Scanguage (no direct benefit, but allows early problem identification)
oil catch can (eg. provent)
turbo timer (is this even needed on a Paj?)

I've read many threads on each of these - but couldn't find discussions that compared their relative benefits or identified which first.

Any suggestions relating to extra servicing that would really make a difference to longevity would also be appreciated

Newbie - so apologies if covering old ground

You have got them covered mate. I wouldn,t waste my money on a turbo timer. I,ve lived in the top end for over 20 years and all my turbo cars have never had a timer. Good oil takes care of the heat. If it is a particularly hot highway run, before turning motor off..let idle for 30 seconds. This wouldn't occur very often.

I would use the MM oils as your vehicle is under warranty and they use full synthetic anyway.

Scan gauge or ultragauge..ultragauge doesn't show your auto transmission temp BUT I bout an engine watchdog that has 2 temp sensors..1 for engine block and 1 for the auto.

I have the dobinson 3 micron that I installed as the secondary unit. Also have installed the provent catch can. Have aux battery mounted in rear 3rd row seat tub as I wouldn't use the 3rd row anyway.

Make sure you take the car back at 1500 klms for an inspection at the MM dealer you purchased from.

cheers

Thanks Dicko - good to have the need for the T-timer clarified.

Is it possible to fit an aux battery and a provent and extra filter under the bonnet, or do I have to do as you have and put the battery elsewhere?

Which engine protection/longevity mods first?

1. EGR mod
2 Regular oil and filter changes. Consider 7.5k- 10k intervals and good quality oil.
3 Second fuel filter - minimum 3 micron 95% efficiency eg Donaldson
4. Jury is still out on oil catch can if EGR plate or electronic block is filtted
5. Tappet adjustment a must at 30k - by the book during capped price servicing and perhaps max 60k intervals thereafter

The jury may be out on the provent but even after 4000 klms I had a filter full of clean oil that would have made its way to the inlet manifold...Jury has ruled for me...guilty of a good thing..

HI Dicko,

My comments were related to a brand new vehicle fitted with EGR block.

Out of interest how many km has your Pajero done.

Mine has just clocked over 4500. 3 months old. Oil is as new. I reckon about a teaspoon of oil was in filter. Had provent on since new. Had new suspension put on last week by a mate of mine who is a marine/diesel mechanic. Very smart cookie actually. He did comment that although not necessary, the pro vent will minimise oil getting into intake. I also have the SPV plug and play module. I just reckon that at around $230 it cant hurt and will help some.

And into the combustion chamber where it would have been burnt.
If you have the egr blocked an oil catch can is a waste of money IMO.
Just something else to look after.

1. Fuel filter. 2 µm mounted before the factory one.
2. SPV EGR mod.

Nothing else is necessary. SPV mod means no exhaust in inlet system so a little oil is no problem.

Later, when you crave more power, a Dominator 3 chip from SPV with EGT gauge and Dawes valve to control boost.

Thanks Guys - I acknowledge that this is a question about priority and that everyone has their own threshold about what is worth doing. I appreciate all the comments and explanations of why you think each mod is worthwhile or not! Simon

PLEASE NOTE:

NOT ALL MM DEALERS USE FULL SYNTHETIC OIL

My local MM dealer uses Valvoline Semi Synthetic.

I would most certainly be using full synthetic.

No worries Ticky. My advice is that whilst you have a reasonably new vehicle under warranty I,d use the original MM oil. There can be no nasty surprises if anything goes pear shaped. Don't forget hundreds of thousands of heavy machinery are simply using shell rimula x as their oil of choice..

Rubbish.

If the oil meets the specs required by MM use it. You can bring your own oil to
a warrenty service and get them to use it.
It will not effect your warrenty at all.

On the NW Pajero a solid egr blanking plate can be used and it wont cause any check engine light issues.
So no egr resistor mod is needed.

As far as im aware, no one has tried the blanking plate on the NX and let us know if it doesn't cause any codes.

For my money I would be trying the blank plate first and see what happens.

It may free up some money to go towards other mods like the fuel filter.


The Torque android app is a far cheaper alternative to a Scangauge.
Any gauge a scangauge can read the torque app can too.

The Torque interface is far superior to the scangauge in my opinion.

I had a phone holder and incar charger set up for my old phone to run torque in my old ute.

When I updated my phone, my old phone lived in the ute primarily to run torque.
I took it out of the holder and put it in the glove box if I was parking somewhere I thought might be a bit dodgy.

There is a similar app for iphones but I dont know what its called.

As someone else has said, no need for a turbo timer on oil and water cooled turbos, just take it easy for the last couple of kms' before you get home or just sit and let it idle while you finish listening to a song on the radio when you pull up, before shutting the engine down, if you have been driving hard.

Matt, what else is needed for the android Torque app to work? Also, I plan to get the blanking plate to try on my NX. Anyone in Adelaide care to lend a hand to help me install it? I plan to do it after the school holidays.
