Toyota V35A-FTS Engine Teardown (15 Viewers)

I just ran across this video on YouTube that I thought you would find interesting. It’s an engine teardown of a V35A-FTS engine from a Toyota Tundra.

Plastic hoses/pipes for coolant (around 13:30 mark) reminds me of my 958.1 that I traded in for the GX. Porsche had also used plastic piping that were notorious for cracking, believe they either had a recall or updated the part to metal ones...luckily I had the metal version.

Seeing the intake valves makes me wonder if it's worth getting a catch can but think I'll hold off on any engine related mods atm.

I found his comments at 50:26 of the video to be interesting. He questions Toyota attributing the root cause of the main bearing failure mode to machining debris. He asks why the rod bearings weren’t also damaged as they share the same “oiling circuit” as the main bearings. He also notes there was no debris in the top of the engine and no damage to cams, cam caps, cam towers, etc.

All that said, he also notes that there’s a lot to like about this engine.

Hopefully Toyota has found the root cause of this issue, and the engines that went into vehicles after that point in time (as well as the engines that replaced recalled engines) will perform well and not be subject to the same failures.

Without question it's interesting video.

This guy has a great job, earning a living tearing down failed engines and making videos showing every step in the process.

I've been reading the comments (2700 in two days), and just took a break from doing so. From what I've read so far, commenters agree with him on the point it's not machining debris.

Curious to see if Toyota will change their tune. I’m sure they have watched the video. I would think they have performed their own tear downs already,

The problem is that Toyota is replacing engines with the same defective engines.

Agree. It would raise incompetency to a new high if they haven't already done so.

I've watched the last 10 -12 minutes of that video twice so far, and it leaves me with a deflated feeling of 'did I buy the right vehicle'?

Well maybe since our version has less hp and torque we will be safe. That being said , uncertainty has crossed my mind too, especially after dropping 90k+ cash for my Lux+.

Seems like mostly tundras , not many LXs GXs and Sequoias that share that Motor.

Maybe I misunderstand your wording. That V35A-FTS engine is in all GX 550s.

But there is a specific data range into which Lexus has supposedly narrowed down the issue. The first post in a thread on here named '2024 Engine Recall' has all the details.

My Lux falls well outside (well past) the end date. But that video raises a tiny bit of doubt.

I’m talking how Toyota does recalls , they do it in batches … I wouldn’t doubt if the 2025s end up on the recal

The comments in that video are flat-out great reading, to me. I'm a sample of one, so YMMV.

One comment that caught my attention compares The Car Care Nut and I Do Cars (this video). The main points are TCCN has to put his cars and engines back together, where IDCs strips down a failed engine and parts it out, example where he just throws the head gaskets on the floor. I don't fully comprehend all the back forth in the 30 replies, ... yet.

I never would have guessed there could be so many ASE Master Technicians with 30, 35 or 45 years experience commenting on one YT video.

According to the car care nut the main bearing part number was changed sometime around April 2024 which is the date of cutoff for the recall. This teardown makes it seem like it’s more than the main bearing but I’m no technician, just a schmuck who finally splurged on a car that may have major engine issues.

Would like to see solid evidence in this regard, i.e. the main bearings failed on the replacements. It could also be the technicians did a poor job with the swaps.

 

[JoeRob]

If the replacement engines are "the same defective engine" Toyota/Lexus must have made a whole lot of them and stashed them in a warehouse somewhere.
I give some credit to Lexus knowing not to swap out a bad engine for a - bad engine.
But hey, even GM knows better than that..... Naw - they don't either.
So far, my '24 GX is not included in the recall as it was manufactured in December, '24. I don't have any idea when the engine was built but.....
