Egr blanking plate 4.2 non turbo cruiser ,

“May be technically illegal”

No maybe about it, it is definitely illegal & something to fail a roadworthy on. If a car is fitted with the anti polution gear from new you are not allowed to remove it or disable it........ possibly unless the vehicle is for use off road only I believe.

If so why it’s ok to pollute our planet when not travelling on a gazetted road I don’t know.

My car is of course for off road use only, is a turbo diesel & recently had it’s EGR valve blocked & I’m a hypocrite.

Unlike others here, I have found, that it further enhanced the improvements in smoothness & drivability that were gained by fitting a 3” exhaust a few weeks before the egr block. Makes sense because the cylinders are now filled with a higher proportion of combustible air (oxygen), rather than semi combustible exhaust gases.

Totally useful information. Not!

So gbc your telling everyone on here that you cannot fit a catch can to a 1 hz motor ? Yet others have fitted them.....

How does that work?

My apologies. So toyota put an egr system in for the last 4 years of a 17 year production run? No surprises there I suppose. Last 1hz I had was 1995. This one is evidently post 2003.

GBC..You can bet it was a result of the greenie laws. I have it in my Pajero and immediately bought an electronic device to negate its operation. The amount of trouble and expense involved in maintain this ridiculous piece of gadgetry is insane.
Catch can works well on any vehicle with breather to air intake.

As I understand it, the primary role of a catch can is to keep the oil and crud out of your intercooler, thereby keeping it clean and maintaining its efficiency.
May be wrong, but can't really see a use for it on a non intercooled engine.

It did from 09/2002,jamesw...the update model. Changed pump, inlet manifold, more fuel consumption..and an EGR system.

Use of an oil catch can is more beneficial in a positive atmosphere crankcase, a turbo engine, particularly a post manufacture turbo-ed 1HZ. Its gunna die an early death anyway..but limiting the rebreathing of crankcase mist helps a little bit.

I was unaware that a EGR system was fitted to newer 1HZ engines, so thanks for the info. As they are not a power house anyway, it could only be detrimental to the small amount of performance they have. I have a factory turbo 1HDT with a hi flow turbo fitted plus a Provent 200. It works very well and I would consider it a must on newer turbo engines to cut down on the build up. Another product to consider is Cost Effective Maintainance I use it and can verify it really works.

You can see what I was talking about with the development of goo in the system - doesn't actually hurt the engine itself but has got to upset breathing and any sensors in the inlet system.

So a lot of supposed experts on the forum say you do not have egrs on your engine but here you are playing around with them on your engine.

If your EGRs have been playing up and not opening and closing when they should - eg open when power is required - you might even find a bit of extra zoom zoom but if they were working fine then there will not be any difference.

All good mate ,been doing a lot of research ,and I hope I get rid of a few issues etc blacksmoke under load,flat spots,done the injectors a few months ago,might go for a exhaust next well see how this goes.
Thanks again Garry ,

Jonesy1, sounds like yours is a post 09/2002 1HZ.

Good luck eliminating the black soot under load. The only way you will do that is to flip the anti tamper cap and wind back the fuel pump fuel stop...and in the process restrict your very mediocre performance as well.

They are a dog in the 105 or 79/78 Landcruiser, and Toyota should have been taken out the back and shot like a mangy dog for having introduced the update 1HZ, and not just fitted the 1HDFTE to all models.

Your wasting your time mate, just eliminate the EGR, and enjoy your miniature performance post 09/2002 1HZ, excessive fuel consumption and sooted back doors.

Don't mince ya words ol wholehog sounds like you've had a bad experience ,thanks for the positive comments ,,,,,mine is a 2005 ,not sure if that means much to you though,

Wholehogs right. I drove more than enough of those late model 79s on the highway. They went faster in 4th than 5th. Many couldnt top 120kph.
at the time the v8 was introduced the 1hz was the slowest mass produced vehicle on sale in Australia
