Hi Gossy,

Never had to buy one myself but maybe try a shop that does turbo installations and modification. Some have dyno setups and do all sorts of performance work for diesels.

just checked and they don't do one for my engine. Looks like no-one does.

.

I just cut one from a discarded jam tin. Still OK after several years.

Interesting story went with it. The Camry had been 'hesitating' for some time and Toyota Service could not even notice it, let alone correct it. Then an ex-Toyota apprentice happened to visit and I quizzed him about the 'hesitation'. His prompt response was "faulty EGR valve". I blanked it off and no more problem. I do not use Toyota Service anymore!

I did find on the net that using tin is ok. My only concern with that was the heat (could it handle the heat)? One, I don't know how hot it gets in there and two, I don't know the heat tolerance of tin.

Well it's not actually tin Gossy. It is steel with a very thin coating of tin. However, being quite thin steel I did (and still do) have concerns as to its effective life. But then, it is easy to replace.

Hi Allan,

It begs the question, if the Toyota mechanics cannot get something as common as a Camry right how in the hell are they going to know what they are doing when it comes to 1HD FTE which are not that thick on the ground.

Imagine having them work on one of the new V8 diesels.
You would want to be sure you got their best bloke on the job.

Cheers, Bruce.

Hi guys,

I think the problem as Bruce said is get their best bloke.

Only thing, their "best bloke" has a keyboard and screen and if "he" can't give the right answer it's game over.

Well in my case, their "Best Bloke" no longer works for them!
I had a 6-year warranty on the Camry which is why I stayed, but no longer.
However the Camry is a great car. Six years and the only fault has been the EGR valve. The Camry before this one also did 4 years with no issues.
Mind you Toyota Service does not get their hands on the Troopy. I have a first-class independent bloke looking after that.

Incidentally, there is no need to shape the blank with holes for the studs. It is much easier to just cut it as a rectangular tab that sits between the studs to cover the hole. It will seal just as well and you can simply loosen the nuts and slide the blank in place.

Cheers
Allan

G'day mate, I'm not sure what state you're in, but Sprint Auto Parts are a good bet! Here in SA the store at Munno Para is the go to store for EGR blocking plates/chips etc.

I personally wouldn't even consider cutting one out of a jam tin lid. When it lets go, bits will find their way into places they shouldn't & bang! $$$ ;)

Cheers,

Kevin.

Good point about debris Kevin. Thanks. I'll review my setup. Soon make a new "blind" out of heavier gauge.

Gossy
If you remove the EGR valve body you can make a plate from sheet stainless steel.
Many people, drill a 10mm dia hole in the middle.
This allows some EGR flow when the valve opens but restricts the full flow.
This means the EGR valve mechanism runs cooler and the small flow allows modern ECU system to detect some flow and they usually don't put up an engine fault code.

The low flow of EGR mixes with the incoming airflow and even if there is some blowby oil mist, it is quantity and heat limited so doesn't turn the combination of the two into a build up of gunk in the inlet manifold and throttle valve area.

I don't like the square metal plate where the overhanging casting is unsupported. If tightened too much it can break the casting or distort the casting. Then to make it seal properly you have to "face" the valve assembly.

Gossy.

I made one last Saturday night while watching tele, for my GQ 96rd28T.

I used this site as a guide.

http://www.nissanpatrol.com.au/forums/showthread.php?40-Blocking-the-EGR-Valve

Took me about half an hour or so.

Seems to have a faster pickup when taking off. Turbo is kicking in earlier, and seems to be hanging in longer. This is in town. Have not been on the highway yet.

As the EGR is vacuum controlled and the wiring on the plugs on top just measuring it's performance all you have to do is blank off the vacuum line and the EGR stops working and stays closed.

Putting a plate between the EGR and manifold won't do the job better.

Also making a plate with a small hole on it might work but as the ECU measures the EGR flows of both High and Low it would be hard to get it exactly right enough to fool the ECU and not get the little engine light on the dash.

I have blanked off the vacc line and the eng light stays on and as long as the code reader in the Scangauge only reads 4010 I know it's only the EGR that is disabled.
