Great job mate. Thanks for taking the time to document this for us all 👍
Thanks Jason
Great job and very detailed. Thanks for sharing
Most welcome and thanks for the comment 🙂
hello mate…ex pat Kiwi watching from over here in Oz…had the EGR and intake manifold decoked professionally on my 2004 Hilux Turbo Diesel…they used a pressure clean and solvent system…cost me a pretty penny but it was worth it…also had the EGR deleted at the ECU..(no blocking plate). One of the best mods you can do on these 1KZTE motors is a 3 inch exhaust…you don’t have to spend big on a stainless steel name brand…just go to any muffler shop and get a mild steel mandrel bent unit…does exactly the same thing as a high end system…a 3inch hole is a 3inch hole…they can do it in under 4hrs…$480 bucks…thats en extra 3hp right there …money well spent!
Thanks for the comment. Definitely goes better with that muck cleaned out of the intake and EGR blocked off.
Yes I have heard about upgrading the exhaust, especially the dump pipe off the back of the turbo is really good upgrade as the factory bend tightens causing a bit of a bottle kneck. Have been meaning to make a new exhaust up for quite sometime now, although my time seems to end up going into my other cars unfortunately.
Greetings from Sydney, Oz. Great video mate. Well done, great music in the background too !
Thanks Dave for the comment. Nice to document and help others. Hope all is going well over in Sydney
>>great music in the background too !
I found it really irritating, having the radio playing constantly in the background.
Great video and clear walkthrough of the job!
Thanks
@@4AGEEDGarage do these 1kzte engines have EGR coolers?
@@russellking9762 no they don't, hot exhaust gases flow through the engine which decreases performance, and obviously adds more heat which isn't good for the 1kz heads which commonly crack.
1KZ engines benefit from:
Opening up the spill valve a bit more
Bigger exhaust
Air filter upgrade
EGR system cleaned out
Bit more boost
Injector nozzles cleaned/replaced and opening pressures reset.
Factory ceramic glowplugs replaced with Italian made Twin-coil steel glowplugs.
Factory hose from intercooler to inlet replaced with quality silicone hose.
The small charcoal filter in the boost pressure line deleted and replaced with a tiny paper inline fuel filter.
Replacing EDC-V4 injector pump ( which really are uber reliable) with a 4M4O-T or a modified 2L,3L or 5L mechanical pump.
Thanks for the comment
Good job 0:35 0:37
Great. Im on the 11 am bolt reeeee
Did you end up getting the thing? If so how? I’m watching the video and I got my breaker bar but I have 0 clearance to do shit. The egr exhaust pipe is in the the way for a regular ratchet. I’m pretty hard stuck here
I started taking my intake off today but the EGR nuts are really seazed up so will soak it with penetrant and try again in a few days. I see you got your EGR nuts off the intake side. My intake looks about the same as yours for build up of crap. Doing the injectors, timing belt and install an EGT. Along with a list of other modes and upkeep. Thanks for showing me how it is done, what to expect and the confidence boost. Nice job and look forward to more.🇨🇦
Hey, not good your nuts are really seazed up. Mine were all fine besides the one on the exhaust side of the egr valve pipe. Sounds like your doing some good maintenance and welcome about my video helping.
I'm about to replace my injectors soon, looking forward to that. I'm getting more milage to a tank of diesel too since clearing out intake too.
@@4AGEEDGarage thanks for replying. We will get there, may take some time. I will definitely watch for the injector video in the future. I am sure it will be thumbs up worthy. Cheers!
Thanks for the thorough video! Have there been any downsides to blanking the EGR? Does it throw any error codes?
Welcome, no downsides at all or any error codes. I was expecting an engine light or something to appear, but nothing. All vacuum lines and electrical plug still connected to egr valve. Performance is better now without the exhaust gases going through the head and ports clean.
@@4AGEEDGarage Great to hear, I’ll be doing an intake cleaning on my Surf sometime in the next few weeks and I’m also planning on installing an EGR blanking plate. I have a ‘98 JDM Surf that was imported here to the States, so I’m sure it’s way overdue for some intake maintenance!
And will it be good if i block my egr with a plate i have recently overhauled my engine and my rpm doesn't go above 3 thousand rpm and it giving me average around 4 km per litre please help me with this problem
hey man nice video its helping me tons. Having a problem getting the injector fuel lines removed to get that last intake manifold bolt on back bottom. did you take the injector fuel lines out then remove the manifold or take out the manifold then the lines? Because the lines block me getting that last bolt out easy. its been a task thats for sure. thanks!
Hey mate. Thanks for the comment. Yes I removed the injector fuel lines to help. Unscrewed from injector pump and injector.
Thanks for sharing, what camera do you use for your videos?
Just use the camera on my phone which is Samsung s10. Just use basic settings 1080 and 30fps I think it is so it doesn't take up top much memory. Edit everything on my phone also
Hey man, I’m based in waikato and have just done the first half today.
Just wondering what you did with all of the vaccuum lines and sensors that went to the egr?
Awesome video by the way!
Hey Nick, thanks heaps. Sweet just over the hill. I'm in Tauranga. I left everything connected up as it was from factory but only fitted the blanking plates to stop the exhaust fumes from flowing around into the intake. Hope that helps
Awesome that sounds like the way to go. Bloody hell small world!
Keep up the videos man theyre great
Got a toyota carib as well and pretty keen on putting a 4age head on it! Probably easier on paper than in reality
If your going to attempt this bottom rh 12mm bolt is a bitch there is a big nut on the egr but good luck getting a spanner in there
how do you fit a trundle of flange on the throtle body connecting the intake going to tarbo charge ? please help a video
Just hose clamps. Very simple
hey man, did you removed the butterflies in the throttle body as well? i did blocked the EGR both ends today and just reading some forums saying it will have to remove the butterflies if not it will restrict air flow? how is your engine going so far? any issue after blocking them?
Hey mate. I cleaned the main intake manifold throttle body only, but not the egr valve butterfly as it on the otherside of the blanking plate, no gases flow through egr valve since being blocked off.
My Surf runs great and not one issue since blocking it off.
Hey So those two bolts on the exhaust manifold I got the top one, but the bottom is stripped and afraid I’ll snap it if I go any farther with a wrench extractor bit. So if I just disconnect the egr pipe from the intake manifold side where it runs into the egr itself 2 bolts there and block that side, will I have back pressure issues? Like higher egt’s as well? Since exhaust gas will still be able to move through the egr pipe before the manifold intake? Thanks from America 🇺🇸 great video.
Also did you have to bleed injector air or prime the fuel system as well, or does it all sort itself out once running for a bit.
@@SamFixesThings thanks for the message. No good about your stripped bolt. Unsure if it will disrupt flow if the exhaust side isn't removed. In my mind I think there would be some disruption but I'm no expert. The injector pump sorted itself out by itself for me, had to wind it over for a bit before the diesel reached the injectors.
@@4AGEEDGarageThanks!
I see that you made sure the valve was closed on every intake that you cleaned. But won't the leftover soot and crud still be able to fall into the cylinder when starting the engine?
Was flushed right out multiple times with brake cleaner after scraping, wiping the ports. Any possible crud would be minimal, if any, and no difference to the rest of the crud the engine has sucked through from the egr in the past.
@@4AGEEDGarage Allright! Thanks!
What material did you use for the EGR blanking plates?
Hey, just 1.5mm steel plate cut to same shape as gaskets on exhaust and intake sides
@@4AGEEDGarage Great, thanks!
Hello sir i recently owned 3rd gen 4 runner 1kz te when i put it on drive some times for 4 to 5 seconds it wont move but after 5 seconds when i accelerate it. It start moving kindly help me with it
I don't know the answer to your issue sorry.
And to your other comment yes block off your EGR to stop that carbon going into your intake.
How many miles had it done when you cleaned the inlet manifold.
270,000km, so converted I think it's around 167,000 miles
If you're based in Auckland would you be interested in doing that exact job on my 1KZTE Surf?
Hey mate. Not in Auckland sorry. Any diesel engine specialist or mechanic would probably be able to carry out the job if asked. Definitely worth it, runs so much nicer and about 80 more kms extra out of a tank of diesel.
Hey when you took your inlet manifold off did you remove the fuel lines first? I’m having trouble getting the last nut in the bottom corner. Also idk how you got the nuts off for the egr exhaust pipe. That’s footage I would pay for. I had to chop mine
I used a special tool to remove the fuel line nuts, same one as pictured on this link. www.supercheapauto.co.nz/p/toolpro-toolpro-spanner-set---3-8-drive-crows-foot-flare-nut-13-piece-metric/591843.html#start=42 .
Egr on exhaust side I brought a cheap socket and cut it down for one of the bolts and used a strong bar. The bottom bolt was the challenge, top one was fine and loosened straight away.
@@4AGEEDGarage I’m having a hard time getting that last nut holding the inlet manifold on. It’s right next to the oil filter, the very far bottom right nut. I had to remove the fuel lines first. I hit it with some pb blaster. Hoping it comes off. Not much clearance.
Im kinda screwed if I don’t get this manifold off because the EGR is stuck between the firewall and manifold.
Everyone’s videos made it look pretty chill. But the hilux surf has no clearance for any of this job. It’s been rough
@@N8_10 have you removed your oil filter to give you more room?
Mine was straight forward and they all came off reasonably easy. Might need to use a strong bar to help crack it without doing damage.
Must be very frustrating it hasn't been straight forward.
@@4AGEEDGarage I did remove the oil filter. I used a small 6 inch ratchet and threw my whole body into it. I finally got the Manifold off and now everything is ready to clean. Technically it was pretty straight forward. But the surf just felt like it wasn’t meant to do an egr block without lifting the engine.
did you see an improvement in fuel economy?
Hey, I just finished a full tank of town driving and I would estimate around 40-50 extra km from my tank. I'm looking forward to see how it goes on long distance.
