Yeah, those original kit instructions were horrible; I vastly improved the instructions now and the pictures are in color with better contrast. I *really* appreciate your video because we're trying to make a kit specifically for 2nd-gen and this is a big help! Thanks from Lextreme
Super helpful video! I just did it on my LS400 because of a cracked EGR pipe causing a rattle. I’m now getting code “P0401 Insufficient EGR flow”. I don’t mind the check engine light, runs so smooth now it puts brand new cars to shame.
First of all thank you so much for this lovely vedio. I enjoyed each second ☺️. I have same car engine with same model . I appreciate the effort you did to make this vedio happen, fixing , filming and editing, it's not easy thing , I really know what's that mean . I have advice to you , and its very important, some times when i start my car ( when its cold ) a punch of white smoke comes like from 20 to 30 seconds, then disappear, not just only this , also I realize the feul consumption is very very bad . I changed so many things , but the problem still there 😢. Finally I discovered that the power steering upper air valve is broken, you can find it directly under the fluid filler ( rezevur) . Also the hose come out from the valve it self going to the air intake was have air leaking ( same spot you mentioned its broken , its very easy to broke. Simply I solve the issue by deleting the valve. Just stick a rubber pieces Inside the hoses and cover the outlet pipes with rubber covers . No more white smoke in early morning, no more insane fuel consumption. i owned my lexus LS 400 now for 18 years and it has 390K miles , around 630K kilometers. And still running smoothly. I am keeping it for ever . Nice thing to do : change the back plate lights with LED ones , it will look super amazing.
Great video man! Looking forward to more to come. Just removed cruise control from my 92. prefect time to remove slack from the gas pedal cable. Came in at 3.6 lbs removed
I did end up with a permanent “incorrect purge flow” code. Probably due to my charcoal canister and vacuum valves all “falling out” of the car during this. Other than that, no codes and no issues that I have seen from these mods.
Great info.... Thanks for sharing... Question for you is My SC400 when I first start is not doing what the normal high idle in the beginning of the day ..do I need to chance the cold injector valve ?
Hello , i am harry, i leave in France and I have problèm with my lexus ls400 96 ! Many smoge at the back of the car ! Do you k.ow very well this engine ? Thank you 'harry
Hi, I currently have a similar SC 400 (1992), and my Coolant Reservoir is leaking at the Low Coolant Sensor...I watched your video, and found out that your tank does not have this sensor, but it has a cover on top of it....is this an original resevoir tank ? or you modified to bypass that Sensor ? please let me know. Thanks.
Might be something they changed for the engine modification for the 96 model year. Mine did not have any sensors on the stock reservoir, and it was not modified until I removed it from the car for a different setup.
@@elementalcivik , I tried to look for the reservoir without the sensors same as the one installed in your car, but I can not find this one ... I searched on all websites, I only see the one with the hole where the Sensor is needed to install in there...The problem is this Low Coolant Sensor was discontinued from the Factory....😢😢
On mine I believe it went into the 2 wire connector with one brown, and one black with red stripe wire. I think it originally plugs into the temp sensor on the egr unit, been a bit since I did that though
Removing the front VCV doesn’t throw any codes? Just leave it unplugged? And did you need to use the small vacuum line that was with the kit? And what did you use to block off the back EGR pipe?
If I recall from back when I did it, I used vacuum line to basically bypass some of the components that were removed. Basically connecting vacuum straight over to other components without the VSV’s or anything in between them.
Thx , I will pay my mechanic to do mod or replace egr etc, because that is a lot for me & do not want my hand busted up. I wonder what was total hrs of time for job.
I bought it off of eBay. Listing title is: “Lexus (SC400 or LS400) 1UZFE EGR Delete Kit” It’s basically the same kit that used to sell on lextreme, in fact the instructions look identical to what you find in the old “how to” on the Lextreme website.
@@elementalcivik Someone had a few kits left and they're now gone. We only sell the kit on our website and have updated all the hardware, plates are now laser-cut and the instructions are vastly improved. www.lextreme.com/1uzfe-egr-delete-kit/
For me really, just simplifying and cleaning up the engine bay. The more space and ease of working on it, the better. That rear pipe on these is a known failure point and repairing the system gets expensive in a hurry. So basically just avoiding future repair bills and ditching the whole system.
@@diszruptiveent3634 Stock ECU should be able to compensate for any airflow differences. Other than a purge flow code, it hasn’t caused any issues with the computers.

Definitely took some pondering and interpretation, haha. Glad to hear they’re updated, and that my video could be of help!

Incredible! Thank you for taking the time to make this video. I look forward to doing this to my LS, as it also has the second generation 1UZFE.
So glad I have a ‘92 to do this on instead of a later model lol, thanks for the video!
Replaced starter, fuel pump, egr delete this weekend, effing hell, but she runs like a champ.
That’s quite a project, glad to hear it’s running proper!
Great video man! Looking forward to more to come.
Just removed cruise control from my 92.
prefect time to remove slack from the gas pedal cable. Came in at 3.6 lbs removed
Hey, thanks so much! Every pound counts! I need to tighten up my pedal as well I think. Got a lot of play in the pedal for sure
Appreciate the video, so look forward to getting the egr pipe in the back of the engine.
Really enjoyed your frustration. I can relate 🥹
😆 it never ends with the frustration
THANK YOU FOR THIS CONTENT!!
What terminals did you plug the resistor to
awesome video! great reroute to the throttle body, how has it worked so far? any diff codes?
I did end up with a permanent “incorrect purge flow” code. Probably due to my charcoal canister and vacuum valves all “falling out” of the car during this.
Other than that, no codes and no issues that I have seen from these mods.
@@elementalcivik haha right. What year is this ? 96
@@rustypotatos Yep, mine is a 96 model year
Was there a metal gasket on both sides of the egr pipe that’s came off the exhaust manifold ? If not which side was it on
How did you remove that connector from the valve
Did you replace the charcoal filter with anything or just link the hoses?
For now I just have a breather filter on the vent line, linked the other hoses
Great info.... Thanks for sharing...

I rounded the upper two bolts on the Egr pipe….
I just bought one
So did I. Done anything to it yet?
@@mattl1925 nope it's getting diagnosed last oil change sticker was in 06, it sat for a while, not running
@@dronetrucker yeah that's a long time. Easy motor to work on though. Clean body at least?
@@mattl1925 Yup zero tears on leather no rust, same owner since 1994, doctor owned.

Still in CO? Any parts to sell? I'm in the springs and I have a 98 sc400 needing done things

Where did you put the resistor in which cable? Because my light for the EGR coming up
On mine I believe it went into the 2 wire connector with one brown, and one black with red stripe wire.
I think it originally plugs into the temp sensor on the egr unit, been a bit since I did that though
is there a benefit to removing cruise control?
Not specifically. I just wanted the cables and module out of the engine bay. Just stripping anything “extra” that I don’t need.
Is the check engine light appears again after while?
Yep. It does not like the airflow
@@elementalcivik how 🤔 can you know the error cods in your car ? Which way you use ?
There seems to be more than one way
@@hussienabukhalil2012 I have a little wifi scanner that can pull the codes, app on my phone reads em off.
Removing the front VCV doesn’t throw any codes? Just leave it unplugged? And did you need to use the small vacuum line that was with the kit?
And what did you use to block off the back EGR pipe?
Since the pipe is now just an open pipe on both ends, I left it.
I do now have a permanent “incorrect flow” code, but it still runs happy as ever
If I recall from back when I did it, I used vacuum line to basically bypass some of the components that were removed. Basically connecting vacuum straight over to other components without the VSV’s or anything in between them.
Will removing cruise control system, Throw a code?
No codes, no. It just ceases to function. Dash light doesn’t even come on when I press the control stalk now.
Thx , I will pay my mechanic to do mod or replace egr etc, because that is a lot for me & do not want my hand busted up. I wonder what was total hrs of time for job.
Took me a couple evenings, I’d say 6-8 hours in total figuring it all out
Thank you at least I know labor is going to be $360. Is the delete kit on lextreme legitimate because there are fake ones circulation.
Do you have a video for head gasket replacement because I need to save money some how?
@@shaunadapettway3890 If you buy it straight from Lextreme, it should be their legit kit.
@@shaunadapettway3890 I don't, thankfully haven't had any head issues on mine so far.

That rear pipe on these is a known failure point and repairing the system gets expensive in a hurry. So basically just avoiding future repair bills and ditching the whole system.
@@elementalcivik thank u for the explanation and u got the point !
Yes, I believe this failure cause of bad gas fumes in my car
Are u running an aftermarket ecu?
Still running the stock ecu for now
@@elementalcivik stock ecu with egr delete? Isnt that bad for the ecu
@@diszruptiveent3634 Stock ECU should be able to compensate for any airflow differences. Other than a purge flow code, it hasn’t caused any issues with the computers.
@@elementalcivik and about the check engine light with the not existing egr
Btw catch can that shit
Someday I’ll do a follow up video. But, I do have a vacuum connected catch can on it
@@elementalcivik awesome. 👍
