Carbon Build Up, EGR Blank, Catch Can Information

[timbo0279]

Hi Guys,

My 07 ML Triton with 3.2L has had an attack of the EGR blues... Gunk has blocked the MAP sensor port (along with a fair chunk of the rest of the manifold) and the computer shut the turbo down...
Have had the manifolds off and sent for chemical clean, I am going to do the catch can when I put it back to gether.
Curious about the EGR Blank on a 3.2l... have seen some say to put it on the exhaust manifold before the feed pipe for the cooler.. anybody got proof of having it elsewhere??
Also wondering if the CEL limp modes may be caused by the EGR valve opening and backwards pressurising the egr cooler / pipework i.e loosing pressure in the main manifold... if this were the case, a blank between the EGR valve assembly and the upper manifold would make a lot of sense... effectively isolating the EGR system all together from the inlet manifold...
Keen for others thoughts... dont want to rush into this one.. catch can is a no brainer, but the EGR blank is causing second thoughts...

Without doing the EGR, you are going to end back to where you are sooner than later.
To me, the EGR blank is a no brainer - even before doing the catch can.

Thanks Macca, I think I will still do the blank, just want to make sure I understand it and have it in the right place before we set out across the nullabor at christmas time... dont want to have to keep stopping with limp modes all the time in the middle of nowhere...

Apparently the ML 'may' need a small holes drilled in the EGR blank to avoid CEL. Not 100% though, but this thread would probably have the answer.

[timbo0279]

So is the blanking plate on the exhaust manifold before any EGR equipment still the right call??

Hi mate don't need a hole in it ....keep reading till you find the long ranger mod mk 1.... Simple and effective way to not have a limpy.. Blank,catch can and longranger mod mk 1 = trouble and soot free motering.....happy reading...

[brodical]

Think the preferred spot on the ml was on the drivers side...blanking the egr pipe that goes to the pass side...

Yeah mate that's the spot..

[timbo0279]

Sweet!! thanks Brodical.. I will look the "long ranger mod mk 1" up...

[brodical]

Hmmmmmm inside information leak....lol

This is the solution that the Pajero guys were using, as with here on the 4M41. Now solid blank and 12-14mm hole in throttle plate. Works just fine except for slight running on (dieseling ) when turning off.

[brodical]

And also the lr mod mk1 is easier than it sounds...no welding required .. with the steel intake pipe through rad support panel remove it "10 min "drill a 10mm hole in it and fit a brass 4mm barb fitting with a 1/8 bsp thread or any thread doesnt matter in the hole and put a nut/ female coupling on the inside and do it up finish with a little sealant and then put it back together and connect it up...

Think he means the throttle butterfly..but yeah that wasn't appealing to me at all...

[NowForThe5th]

Yeah, in the throttle plate, not the blanking plate. Smaller hole in EGR blank is option but Tony's new mod beats them all.

[brodical]

What was that about Tony's new mod 5th?? Seems the last part of the explanation didn't come through on tapatalk..lol

All that information and more is in platinum area of the forum brodie. .

[brodical]

Yeah so I hear lol ..what else in this platinum thingy lol?? Nar seriously how does it work is it still connected with this / these topics and posts or is it a seperate forum..?couse I spend enough time on this one without having another lol..

[salt36]

Just another part of this forum, but you need to pay the $50 per year to help keep the site running.

Then you are granted permission to see the platinum area.

[NowForThe5th]

Separate forum, mate. Best $50 I ever spent though.

[brodical]

How many members are in there .....probly all the knowledgable ones haha..sorry to take this off topic...moving on ..

180 I think it is.

Hey guys,
Bit of an update, got the manifolds back from cleaning.. looking awesome, sat them in the electolysis tank for a day.. look brand new!! Harris Engines in Osbourne park her in Perth, very helpfull and great service...
Got all the gaskets and screwed it all back together, did the catch can, blanked it at the exhaust manifold and between the EGR valve / inlet manifold.
Took it for a test drive and man this thing has come back to life.. completely different car...

One problem, the reason all of this came about was the gunk build up blocking the MAP sensor port, which gave us a check engine light... after bolting it back together we still have the CEL... but most definately not in limp mode... the thing is a rocket ship now... I am assuming the CEL is left over from the original problem..
My question is , will the CEL clear itself after some time if no more problems exist?? or will I have to take it somewhere and put a diagnosis machine on it to clear the CEL???

If you can get hold of a scan gauge to plug in you will be able to clear the code,or you could try disconnecting the battery for a few minutes
