Marty makes pretty good LS460 repair videos. He shows you just about every step, I think if I tried to do this same repair I'd have this video on my phone to refer to a little. One of the best things about DIY auto repair, is that you can accomplish several other things while everything is apart. For example, I always put some kind of anti-seize compound on the fasteners while they're removed. I always assume at some point I will have to take it apart again at some point, and even if I never do, the fasteners will not seize or rust. Same thing goes with electrical connections and o-rings, a little bit of silicone grease can make future repair work much easier - Also you can do some cleaning of the engine if you have the time, and desire. At least you can spray some foamy degreaser for times you don't want to be spraying water at the engine. Then just come along later once the engine's back together and rinse off the dried degreaser.

It's giving me anxiety just watching, bro! 😆 Those injectors look pretty suspicious. If it were me, I'd probably bite the bullet and buy a whole new set of OEMs. 🤷‍♂️

I have an 2008 LS600h. Had some noticeable random misfiring going on, only while decelerating. Also excessive grey smoke from the exhaust while idling, and poor mileage. Two DIs were tested dripping. Beyond repair, so they were replaced. I am lucky with a good Toyota Lexus specialist in my area. It took them 10 hours. These engines are very complicated. However, it seems to purr as a kitty again! Btw, for some reason all ls600h cars I drove, report some random misfires during decel. In some cars it's noticeable (vibrations), in some cars not. This seems to correspond to the amount of random misfires being reported. Lexus has no bulletin for this, but I just cant imagine this is not a known issue.

Kudos to you mate for taking this on, quite a big job. I really like this 460 especially because it’s AWD which we don’t get on the ones here. Looking forward to the next video.

Love the videos on the LS. I bought my wife a used 2013 this summer with 75k miles and Lexus gave it a clean bill of health after the purchase. But in past week Heater stopped working(easy fix) and now some of the Climate control lighting isn't working. (Why I am looking at LS fixes) Look forward to seeing your project continue.

I had this job done at the dealership for my LS460. They had my car for nearly 6 weeks. I was mad and pissed. After watching this video, now I know the big job that was done.

Keep working hard bro

Can wait to see it fixed

Cant wait to see what you do bro. I also got a 13 ls460. Dont know what to do with it though

I cant wait for the new videos on the ls im in the same boat on my gs460, 😅 like everything your doing i have to do thank you in advance for the content maybe a parts list with the numbers if you could , keep the videos coming !!!!!!

it will run like new when u put it back together 🤞

on my infiniti m56 (100% gdi), I was having some DI issues like a p0300 that I could not find the cause to. I ended up buying new Bosch injectors as a part of the parts cannon firing process. As I was pulling the old injectors out, I found that a couple of them came right out along with the rail. Turns out the seal on the tip was no longer good and was likely allowing air to enter the chamber....hopefully it,s something as easy as a bad seal in your case.

Yea jobs like this seem over whelming before doing it but ends up being not that bad, I had to do knock sensors on my ls430 which they are under the intake manifold similar to this car and I was overwhelmed as I never really dug into a car that far before but after doing it I realized it really wasn’t that bad

Big job

Currently in the process of changing a DI Fuel injector that was misfiring it’s a pain in the ass engine. Good news is I found the problem as soon as the air intake came off…A mouse chewed through the DI wire. Wish me luck when it’s buttoned back up

I just wonder if it isnt a wiring issue by the looks of the previous wiring repairs. Are you replacing the injector plug ends while you are in there? It certainly looks like whoever messed with the injectors before had some broken connectors and chose the cheap zip tie fix. I'm tuned in on this one, keep up the good work!

Hello, when you remove the bolts you should mark a zip lock bag & put the bolts in the bag different bags for each section of bolts you take out.

This video gave me anxiety LOL - I was thinking about getting a 460 but after watching this I don't think that is the car for me. I have a 430 and I can do most repairs but the 460 looks way more complex.

Do everything right while you've got everything torn apart.

ur gonna change all injectors and are they all same on LS460/600 part number? can u say at the end how long it all take 🫡

Nice

I remember seeing a video of lexus mechanic saying, these direct injection injectors cannot be mixed, they are numbered and have to be placed in there original location. Why didnt you just send out the injectors to be cleaned and tested instead of buying new?

Is that a starter under the intake manifold?

Hectic...

How did you diagnose the bad injector? I got a misfire on Cylinder 2 and changed the plug and coil still misfiring

did you have to buy a specific injector? im seeing that they have a main part number and each has a different part number above

Hey Marty you might want to get in touch with the Car care nut he has a youtube channel as well and he is a Toyota and Lexus specialist

Toyotas are easy to work on and never break down everyone knows that and don't depreciate there has never been one in a junk yard that's a fact

Did you get rid of the ISF for something slower ?

This engine looks like a pain to work on

What happened to Misfit Motoring ?

This cars a money pit you'll be working on this for years to come.

would you consider a dodge charger I hear the quality of a dodge is far superior to Toyota these days
