EGR blanking plate to block off or restrict?

[Toyo Junior Member Find all posts View Profile Close Toyo]

So you ended up removing the EGR plate because with the plate on the engine automatically opened the valve more to allow more exhaust air to be circulated back?
When i first read your post, i thought the same. If you install the plate and the ECU recognizes that the air flow is restricted and it automatically opens up the valve more then it kind of defeats the purpose of the plate in the first place.

Correct. Using Techstream to monitor , same temp, rpm. With the plate in with a 7mm hole it showed Actual EGR valve position 92.1%. No plate 49.0%. Never did test it with a full block.
Hopefully someone will come up with a plug and play job to block it but still open if it needs to dump excess boost.

Getting to be a bit of an expert at putting in and out blanking plates. Its out for good now. I was not happy with the EGR position being nearly fully open seems to be defeating the whole exercise. Also it was confirmed that excess boost does in fact go through the EGR so damage to the turbo could happen.
Also the car seems to run smoother.
A local car workshop offered me a plug and play version like the one for the Mits but it was for the Hilux and their Map is larger (Bugger). He is looking at the Prado 150

Yes it's like a teenager addicted to coke. You restrict it, & it try's to get more, it opens more.
But it's restricted! & it works! People have had this for years. It's not defeating the purpose, it can't get what it wants, that's all.
Boost can go through the cooler, but not much does. Think about it, if it did the egr cooler would get oil in it & block up, but they are dry & cleanish.
Don't try & figure it out, leave it to the 1kd expert. 7mm.

Stage 2 will be throttle butterfly mod, as the primary reason it's there is to create vacuum so engine will such egr.
Rougher shut down may be the only negative. Yet to r&d but the r&d team may be expanding, so soon........

Everything you wrote is correct. Except where you said "defeats the purpose".
Forget about the egr opening more. Yes it does, but It's restricted & it works!!!!!

Yes about 90% lol....... Silly thing isn't it?
Just can't get it's hit. But trying so hard. 13+ times less soot 13+ times less hot air.
Clean egr's, less valve recession, clean oil, cold air!
Saved engine!

They are not all badly blocked, so you have to check it.

A 2009 with 207,000k, hard to see, but very clean, quite acceptable for 200+k
The valve clearances were very good.
Maybe this is what mr Toyota though they would b like.





It will b even better now! More cold air!

I have found a direct relationship with abrasive soot & valve clearance reduction.
Dirty egr = bad clearances.
No.4 usually always worst, followed by 3.
To adjust the clearances it's quite a bit of work you want to avoid $$$$
Not selling you valve clearances, trying to save you $$$$

Damn for 207k that looks spotless.
I wonder what affects the soot build up?
Cars with 50K that look almost completely clogged and then there are 100k ones with some light build up only.

That's right. Nobody knows. If they do they are not telling. Toyota should be in the know, & care to share.
Another recall, re flash back to less open egr would be nice. But no! Enough winging maybe 7 years later like the copper seats.
Thats why I'm doing this, someone has to save the hundreds if thousands of 1kd's in oz.

Did this one have a blocking plate ?

No. Some stay clean.

Arise Sir Anthony. Off on your crusade you go with your trusty steed.

Recently noticed my 90,000km 150 was smokin'. Ran the gamut of Bluechem products through, oil flush, oil additive, fuel cleaner and Intake spray (that was traumatic). Stopped smoking and runs a bit crisper I reckon. Then popped in a catch can for good measure.

This is a cut n paste, I agree so thought I'd share.

"An EGR System is a simple emissions reducing system specifically introduced to reduce NOx emission. The EGR system allows recirculated exhaust gas back into the inlet side of the engine. This is a continuous process and the EGR valve remains open on cruise and all the way up to just before wide open throttle. At wide open throttle (WOT) emissions are not tested and so manufacturers close the valve and allow a full shot of fresh air to allow the engine to develop max power.

Mixing hot exhaust gasses with the intake air reduces engine efficiency. The sole reason for using an intercooler is to lower the intake air temps. This makes the air more dense, so we get more air into the combustion chamber. The EGR works effectively to negate the function of the intercooler.

So, the EGR will make you use more fuel, give you less power, cause carbon build-up in the intake manifold and ultimately reduce your engine life. But it does reduce NOx emissions, so we are expected to accept it. Blocking the EGR system gives us two main benefits
1) Blocking the EGR will certainly stop the soot from the exhaust clogging up the inlet manifold.
2) When blocking the EGR port you are redirecting the exhaust gases back out via the turbo, (where it was meant to go).

The turbo now has more pressure turning the blades and the turbo will spool quicker. Most people will even be able to feel this by the “seat of their pants” dyno. ie you will feel a marginal increase in performance and that’s a good thing.
There are many benefits to blocking the EGR port/pipe...
Cooler intake air temps.
More performance.
Less engine oil contamination.
Cleaner engine oil means increased engine life.
Cooler exhaust temps.
No Soot in intake which keeps vacuum / boost lines clean
Increase turbo response
Stop the carbon build-up in the manifold"

would it be possible to completely blank off the EGR and redirect clean to the upstream side of the EGR valve, maybe that way when it opens it will see airflow and think all is well, and hopefully not throw any codes?

Hi Ages Go down to the 120 Threads clever little MOZZ has done it complete with directions.
