On the 4Runner, you CANNOT reach the back (lower) bolts for the air injection valves. We were able to remove the side bolts that connect those valves to the exhaust tubes with a 1/4" socket, wobble joint and a combination of extensions. We zip-tied the wire harness up to the windshield wiper and taped the bolt to the socket and taped the wobble joint. It was not easy, but we were able to do it. The 2 air injection valves were removed WITH the rear coolant bypass and installed WITH the rear coolant bypass. Hardest part of the job, hands down.
I really appreciate this video you made. Probably have to do this to my 04 Tundra... I did a timing belt replacement and I think the o-ring at the water pump connected to the crossover pipe isn't working. I'm hoping it's the bypass gaskets and it's unrelated to the work I did 😢
Same! I have an 07 4Runner. Did the timing belt/water pump. I cleaned everything up, that part seems to be good but then I found out about this new leak. Have coolant running from the back of the engine near the bell-housing (transmission) & engine. Hoping that this bypass/crossover rear pipe will solve the problem!
@@michaelmagaruh7767 My leak actually ended up being from a different place. I'm Glad I didn't go tearing things apart again, check the lines towards the rear of the engine at the top of the firewall. I had a loose clamp And a damaged hose so I had to cut it and reclamp it.
@@dmamrenko12 So yours was coming from the heater core lines? I tried my best to thoroughly check everything from all angles and mine seems to be coming from the intake valley.
Did you replace the Knock sensors? It would be great if you could just update the video description with all the parts#s of the components you changed.
You dont happen to have a complete list of parts with part numbers from this job? If not I can go through the video and get them from what you showed. I have a GX470 which is leaking coolant similar to this so would like to do the same job and change the started while I'm at it. Should be all the same since its the same engine right?
Hi, great video. A bit late asking this question. Do you think a gasket sealant could be applied to the pitted area? Did you consider it? And, if yes, what was the reason deciding against it? Thank you 👍
Can the switching valves be installed on the crossover pipes before it's reinstalled? In other words, install the crossover pipe with the valves installed?
Great video! I appreciate the detail. I’m about to tackle this same job myself On a 2003 LX. Where did you get the creeper? It looks like the one I’m considering from Amazon.
That's a bit of a logistical challenge. My main goal with most these videos is to do the job properly. I try to catch what I can, but there's about 10 hours of undocumented stuff in these big jobs. I'm only one dude with a cell phone so I'm definitely going to miss some steps in the filming.
I know it’s a lot to ask of you but I am about to do the exact same job and is there anyway that you can actually copy and paste all of the part numbers for the gaskets and miscellaneous seals and bolts that you have ordered?
Definitely not where the orings go. I think there's a spot in the front timing cover area (unsure if I touched that in this job) where some fipg is used, but not on the orings. That's a big no-no.
The Lexus manual (commonly called the "FSM") for repair procedures. For parts, I use ToyoDIY. Register for an account and you get the full parts diagrams. Once you learn to speak the "Toyota parts language" it's immensely powerful and will save you a ton of time on the phone with the parts folks. If that doesn't answer your question, let me know.
Thank you. Went to the dealer earlier this week to order parts and gaskets for the Teardown and ordered some incorrect items that I needed up needed but missed some. Way more gaskets them I thought when I removed the Manifold earlier today. Great video!
Got everything back together and ended with a misfire in 6,7and 8. Thinking cause I skipped getting the fuel injectors cleaned. I know #8 and 6# are having a hard time. I should have followed all of your steps 😫

This is exactly what I need to do with my '00 Tundra. 360k on the starter.
Thanks for the video, Dig your vibe!
Awesome video, the way you explain everything really helps. I have an 01 LX 470 and your video's are a great reference. Thank you.
Wow, that was a ton of work! Thanks for sharing.
Big job!
Great you make it look so easy , so many Tips awesome . Superb Video.
wholly Jesus, I watched this whole thing! I think I have a problem.
LMAO! I feel for ya. When I edit these I am very ready to not hear myself talk by the end of it. Thanks for watching though!
The pitting is caused by electrolysis. This can be greatly reduced by replacing your coolant at proper intervals.
Very good video. Would be very interested in parts list as I have the same coolant leak on my GX470 with the same VVTI 2UZ

Only thing I don’t like is the cut scenes something in then it’s how without showing how you actually managed to get the dam thing out

48:58 what’s the part number please ? It’s a hose.
How did you get to the rear nut on the driver side with the wire harness in the way?
If I remember correctly, you can unbolt the harness to move it slightly out of the way.
Any FIPG used in coolant by pass gaskets?
Definitely not where the orings go. I think there's a spot in the front timing cover area (unsure if I touched that in this job) where some fipg is used, but not on the orings. That's a big no-no.
What book are you referencing and what’s the part number for the bypass pipe o-ring. Going crazy trying to find it online.

@@jerryallday That's a bummer! multiple misfires seem like an unlikely problem from dirty injectors unless you had that same problem before the job.
