EGR Blanking, is it recommended or not.

[kevinworld]

when oil consumption is up, blowby ang engine. sometimes, clog Lang yung breather hose adapter from engine to the hose

Main reason people blank their EGR is to prevent soot/sludge build up in the egr and intake manifolds ..... But this build up takes years to accumulate ... Also isuzu engines aren't notorious for sludge problems. Bago pa MUX no hurry for an egr blank. Read more about then decide wether to do it or not.

Sir not to ba a scare monger but soot does build up quickly at least in my case. 14 thousand kms from new 2012 montero. That is more or less a year of driving for me pag bukas ng egr meron nang significant build but not enough to throw a code. Used to gas up with petron diesel max then. Now it's unioil or shell fuel save.

20yrs in business all my isuzu trucks never had any engine sludge related problems nor the L300s i had and have.

Common rail engines are entirely different animals compared to old-school diesels. EGR issues afflicted the Alterra back when they delayed the implementation of Euro IV, I believe... which forced Isuzu to switch back to the older EGR systems. (this is secondhand info from Alterra club members during one of our Shell events... so I am not quite sure which years were affected).

EGR gunking is a common issue with newer diesels like the ones in the Montero Sport / Strada and the Navara.

Sir referring to soot build up in the egr valve of crdi engines. But I agree sa intake manifold assuming well maintained hinde ganun kabilis.dumumi

Naka EGR blank ka sir?

[Tediber Ang]

EGR shouldn't be an issue if you do a lot of highway miles and drive it like you stole it when you can. A friend's EGR was remarkably clean when they opened it. It had 130TKm on the odo, most of them run on the NLEX/SCTEX. That engine lived all its life on Euro 2 diesel.

With Euro 4 diesel I'm not sure if it will still be an issue even if you do mostly city kms.

I had mine blanked. If any, I simply don't like the idea of my car breathing its own fart.

[Tediber Ang]

Fully blanked ba sya ?

Yes. Removed the EGR cooling pipe and covered the two open ports with thick aluminum blanking plates. The EGR valve itself is untouched and the computer thinks it's still working. But the port has been sealed and no exhaust gasses are passing through.

I'm wondering if opening it up and connect it to a 2nd air filter would help reduce pumping losses. So, the idea is to allow filtered air to enter whenever the EGR valve opens up. There's a sort of 'proportioning' butterfly/throttle valve in the D4D that supposedly increases EGR ingestion whenever the EGR valve is open. Opening this port up should reduce pumping losses and further increase fuel economy. Haven't seen anybody do it.

[Tediber Ang]

Thanks for the response ..... Removing the pipe seems a much much easier job than accessing the egr valve itself.

see video posted by bro zix888 (gtv2011 ph) 2 yrs ago regarding the actual behavior of egr valve of a montero diesel engine during idle and when gas pedal is pressed. its in normally closed position during ignition then around 8 secs of idling, it will open and stay in normally open position. it will closed and open as the gas pedal is press.

it's interesting to see those mappings and reference documents

I guess I don't need to graph out a friend's mux then. The video shows how the egr operates on a diesel engine.

[oj88]

Thank you for the video. It's no wonder then why those Diesels produce a lot of black exhaust. And just the thought of the engine ingesting that in, it's just, well, tragic.

I'm now even more glad I've blanked mine.

Same here, bro.

I planted a couple of trees for each of the rides we've blanked... hehehe

I have a wifi obd2 but my egr readings seems always 0% ... I got my 2014 dmax 2nd hand but i don't think it's egr blanked as i do not see any modifications. Anyway i wanted to blank it myself ... And just needed an easy way to do it.

Does it show 0% under any driving condition? It should typically open up while cruising at a constant speed.

[Tediber Ang]

I noticed it was at 0% even at idle ..... Anyway i'll check it again. Don't like keeping the obd2 device connected always as it seems to heat up. And as i know the egr should be open at idle speeds and closes at higher revs.
