2JZ-GE VVT-i Spark Plug Change - Supra and IS/GS/SC

[@azndrgnboi34]

Great explanation! A couple things I learned in this video is that once you apply grease your torque values are different. I also learned that Toyota sells vacuum hoses by the feet! Regarding the harness you should of re-wrapped the entire Ignition Harness in High Temperature Loom. The zipties was a bit tacky and you should of used black if you just had to use them. My OCD was tweaking lol. Overall that was a very clean engine bay! Like the video and keep it up! If you do add a turbo, it would be great if you recorded the entire process step by step. I would watch it even if it was 10 episode long! Thanks!

Thanks for watching!

[@Pallidus_Rider]

Would be nice if you created a playlist for your Lexus gen 2 GS videos 🙏

[@mjhui90]

wow that bay is spotless the any tips on keeping it this clean? thanks for the video

[@redonKiLaus]

Believe it or not, I actually haven't had the time to do a full, in-depth cleaning on this car like I normally do after purchasing a vehicle. I did do a quick degrease and wipedown, but no dressings for rubbers or wax on the painted parts quite yet. I made a video a few years ago on general methods I use to clean an engine bay - some techniques have changed, but they are largely the same still. The video is here: kzbin.info/www/bejne/mIennaBjbcmpbJI Hope that helps, let me know if you have questions, and thanks for watching!

[@chaka9154]

You have any vídeos of your turbo build bro?

[@NwakpaSunday-oi1tf]

I want to confirm as how the range plug wire of this GS

[@McGyVer964]

Thanks for awesome knowledge video but don't forget to covered timing belt hollow with cloth to prevent accidentally dropping something and then air pressure to clear the dusty stuff.

Thanks for watching!

[@ryanchuc2165]

Awesome video. Helped me changed my 2002 Lexus GS300 spark plugs. Do you have a similar video on how to swap out the fuel injectors? My fuel injectors are probably due for a replacement after 15 years.

[@redonKiLaus]

I haven't yet had a need to replace the injectors in my GS - you really don't need to swap them unless you are encountering an issue caused by varnish buildup, but if you want to read through the procedure, here is one from my.is: my.is/forums/f114/fuel-rail-removal-injector-help-291063/ Hope that helps, and thanks for watching!

[@ketchupheadd]

arent the oem plugs denso?

[@pac8447]

Would these spark plugs still work on a stock engine?

[@redonKiLaus]

Technically they would, but I highly recommend buying the IFR6T11 plugs. BKR6EIX-11 are also compatible, but the IFR series are what I run in my stock N/A 2JZ engines. Thanks for watching!

[@Unit_live]

thank you for video, it really helped me

[@redonKiLaus]

Thank you for watching!

[@yourstruly_johnny5843]

Question: My Supra is NA-T on low boost. You recommend the NGK BKR6EIX-11 spark plugs for this setup. Should the plugs be specially gaped or is the preset gap setting fine? I'm currently experiencing misfires. I'd appreciate the help. Thanks!

[@redonKiLaus]

I recommend BKR7EIX plugs for a standard NA-T setup - they run a tighter gap (IIRC, .032") and are colder than stock. I recommend purchasing iridium plugs pre-gapped, as you can easily damage the tip if you try to gap yourself. Hope that helps point you in the right direction, and thanks for watching!

Any more videos!? I went to the channel and didn't see any, unless my phone app is bad again

[@redonKiLaus]

Sounds like the app is acting up then, I have quite a few videos on the Lexus and 2JZ engine. Search "redonkilaus lexus" on KZbin and most of them should pop up then. Thanks for watching!

[@alejandroreyes2200]

Great video, thanks for uploading it. Quick question. I'm getting ready to replace the spark plugs, wires, and maybe the ignition coils on my 2002 GS300. I see the wires are only 3, shouldn't there be 6 wires for a 6 cylinder car?

[@redonKiLaus]

There are only three wires because the other three cylinders get spark directly from the three coil packs, with the wires allowing two cylinders to be paired up off of the same coil pack. I would definitely do all of the items you mentioned, since there is a good bit of disassembly that you don't really want to repeat unnecessarily. Make sure to also replace things like the throttle body gasket. Hope that helps clarify, and thanks for watching!

[@alejandroreyes2200]

Got it. Thanks for the explanation.

[@alejandroreyes2200]

Hi, one more question. Do you also recommend replacing the 3 ignition coils? I see them here amzn.to/2qTJhEy for $76 each. My car has $160,000 miles and the coils are original.

[@ArmyofSeaturtles]

wasted spark system, plugs fire during compression and exhaust stroke

[@redonKiLaus]

Sorry for the slow response, for some reason KZbin flagged your comment so it didn't get to me in the usual manner. If you want to replace the coil packs for peace of mind or if you are getting weak spark in one or more cylinders, you can definitely do that, but if their plastic housings are not cracking and they test as working properly, there's not a huge need to replace them. I have had vehicles with over 200k miles on original coil packs that were treated properly, though if you don't know the full history of your car it may be wise to install some new OE or OEM units.

[@jeecee2001]

Can you please tell me what tools do we need to remove it thank you!

[@redonKiLaus]

All tools are listed in the video description along with links showing where you can purchase them. Not listed are more common items that anyone working on a vehicle should have, like socket sets. Hope that helps, and thanks for watching!

[@owusuguru1150]

What does it mean to cross red the plug?

[@redonKiLaus]

Crossthread - start threading in crooked and strip out the threads as the result. Thanks for watching!

[@BigMikeDeeSqGuy]

How much should I expect to pay for this job??

[@redonKiLaus]

I wouldn't be surprised at a couple hundred dollars depending on where you are shopping around and are located. Thanks for watching!

[@blanked_out_chin]

Got a GS300 and my god, this was ridiculously long to replace the spark plugs. Not to mention the E7 torx socket to use. damn 2jz!

[@redonKiLaus]

Indeed it is, definitely not as easy as on many other I6 engines. I am able to knock plugs out in about 45 minutes after having done a few 2JZ-GEs in the past, but there is a whole lot more disassembly required compared to other vehicles. Thanks for watching!

[@Singleturbo-sk9qp]

I replaced the gaskets and plugs in the same day it was crazy

[@carnaturelovers7072]

@@redonKiLaus And they say Jags are hard to work on apparently 🤣

[@mrNikko77]

Why didnt you show yourself changing the wires?

[@redonKiLaus]

For me it was a simple process since I was removing and reinstalling at the same time, just pull one wire and lay the new one down in the same orientation. Thanks for watching!

[@FernandoRodriguez-sm9vm]

Hi I’m new to the 2Jz community and have a question, is it normal that on the intake manifold side of the head by the spark plugs that there’s a small whole there thanks in advanced

[@redonKiLaus]

Not sure where exactly the hole is you're referring to - on the valve cover, on the head itself, etc?

[@FernandoRodriguez-sm9vm]

redonKiLaus Hi sorry or the late response is on the head itself next to the spark plug hole by the intake side

[@FernandoRodriguez-sm9vm]

I talk to an old friend of mine that work for Lexus for 15years and said it’s normal on this engine that people would go in thinking there car had a leak in the rear main seal and it was those holes on the head that it went to the back of the engine and leak down the back making it look like the rear main seal

[@santotraficante8075]

I'll give you 300 dollars for the engine cover?

[@cotybechtel3466]

I tried changing my plugs today and now my car will not even crank over

[@redonKiLaus]

I'd recommend checking coil pack connections if you're talking about not firing. If it's not cranking at all, something else in the engine bay was touched during the job causing that, as nothing in the vicinity of the spark plugs will cause a no-crank issue. Thanks for watching!

[@blueblinkz6413]

How to check coils if they’re working or not in this model ?!?

[@ketchupheadd]

arent the oem plugs denso?

[@redonKiLaus]

Toyota used both NGK and Denso - I believe they were NGK in the US market but I could be incorrect. Thanks for watching!

[@804MRMAN]

Definitely Denso Iridium.
