EGR Blanking plate NW

[jkwpajero]

I have an EGR delete module and a Provent catch can fitted to my 2014 NW. I purchased the vehicle @ 44,500 ks and have covered about 3,000k's since fitment. I have been searching, trying to find any information on the long term effects of EGR delete modules on engine life. No luck yet. I have been whacked about the ears on a Pajero FB forum for questioning a poster who stated that EGR delete modules are rubbish and should not be fitted, and had my comments deleted. So without stiring a hornets nest could I politely request any true information of late model Pajero engine issues due to EGR delete modules. I am researching the parameters of how the EGR system operates at various throttle loads, and have some information from South Africa that makes sense.

I'd take the opposite approach. What reason was given for why an EGR block would reduce engine life?

Isn't it interesting how some people resent being questioned when they don't have the answer?

Once you've done your research, and understand why EGR is used and how it works, you can decide for yourself the implications of disabling it.

I didn't get an answer before my posts were deleted. I know there are both pro and con sides to the discussion and people get a little passionate about the side they are on, but all I am after is some simple facts about the pitfalls of EGR delete modules. And they seem hard to come by. I have started to investigate a custom ECU tune and have been quoted around $2000, however I believe that includes a intake manifold clean as well with all labour. I already have a Taipan XP exhaust so it would maximize the benefit of the exhaust. The ECU tune will turn off the EGR as well.

Perhaps you could post some of your "simple facts" here, for some further discussion?

Or post a new thread with a summary of the FB argument, and we'll see if anybody here can support it?

Here is a bit of light reading about egr,s in diesel engines...

I am the one after the facts My understanding is, as much as anyone else, the EGR delete module tricks the ECU into keeping the EGR motor closed. My ScangaugeII confirms this. With no recycled soot being mixed with the oil mist from the PVC ( Provent removes it) there is little to no buildup in the intake manifold. All good and well so far. The EGR on my motor also has a "cooler" which reduces the exhaust gas temps introduced into the intake manifold, but the EGR only works under certain throttle conditions. Still my question is "What are the long term ramifications of fitting an EGR module?" Personally, I think that it still uncharted waters over the long term. Pajero's have not suffered the same engine problems as Patrols, nor have any other brands I am aware of. Regular methodical maintenance is key to engine longevity, so maybe if that is adhered to all will be well. I have read quite a few previous posts in this thread and confusion reigns, but it is entertaining.

Well today I forked out just over one thousand dollars to have my intake manifold removed, cleaned and reinstalled also i had the rocker cover removed and had the valves adjusted and the top timing chain guard replaced. The Mitsubishi dealer wanted seven hundred dollars just to do the intake manifold so glad I didn't take it to them. For me the intake manifold will not have to be done again as I have fitted the adapter that plugs into the air flow sensor it's the same as the one that SPV industries make just much cheaper and also the crank case breather pipe has been done as well. No matter what you do with your vehicle if it's a diesel and has the EGR and crank case vapour running into the air intake they will slowly block up. They all do it. I've had the adapter on my Pajero for six months and the first thing I noticed was it idled faster and was more responsive. Today after having the intake and valves done i really havn't noticed any difference considering how blocked it was however the engine is quiter.

There has been a lot of discussion about the ill effects of an EGR blocking device - electronic of blanking plate. My opinion FWIW is that anything you can do to provide the engine with cleaner air and cleaner oil can only be beneficial. Having said this, I can see that under certain circumstances you may actually be getting more oxygen into the cylinders and then you can squirt more diesel in as well and this may make things run a bit hotter. Personally I don't see this as a problem because when you have your foot flat to the floor, the EGR is closed anyway and you are not recycling any exhaust gases (and soot) at that time. Also, you rarely drive for any length of time with the foot flat to the floor, so this is very much an intermittent event.

Question

Re:

3) BEST METHOD IMHO: The turbo, which at the cruise levels discussed here is boosting to around 3 -4 PSI, can supply pressure to the MAP. We need to get this pressure past the Throttle Plate (since it is closed) and onto the intake plenum and the MAP sensor.

Drill a 12mm hole into the throttle plate. That's it. The pressure from the turbo now satisfies the MAP Sensor.

If you employ the following method do you need to blank EGR also?
