Tundra engine recall - interesting news

I am not a lawyer either but what if this happens to someone whose vehicle is outside the recall window and investigation proves the root cause was engine bearing failure. Not going to look to good for Toyota.

 

I was ridiculed and had virtual tomatoes and booos thrown my way for suggesting the one piece main bearing girdle was the cause of the issue.

 

Pure guess, but as long as it isn’t debris….i think they are good….??? Not the customer but Toyotas butt is covered???

 

@Matt2015Tundra did Ryan release information on the upcoming engine changes? I didn’t see anything on Facebook today. Did he state it somewhere else? I thought today, Sept. 1, was the day he was off sabbatical and going to release a bunch of info per his replies on Facebook posts and per the YouTube video interview.

 

No, Ryan hasn't officially posted anything about the redesigned parts that I'm aware of. I suspect he's trying to protect his inside sources, as well as cover his butt against potential liability.

You have to read between the lines, to come to the conclusion the crank girdle and block are being redesigned.

If you happened to watch the Car Care Nut video in which he dissected a Gen 3 engine that had failed, he clearly pointed out several problems with the girdle/block design. The most glaring problem to me was the fact that there isn't anything preventing the #1 main bearing from walking out the front of the girdle.

I also questioned why there was such drastic differences in how tight the girdle bolts had been torqued. He actually had to cut one of bolts, after attempting to loosen it with a 4 foot breaker bar. I suppose that could have been due to excessive heat from whatever caused the engine to fail, but I still found it suspect.

Again, the rumors of redesigned parts are unconfirmed, but it would not surprise me in the least.

 

There was a post on the FB group about a month ago that said a design change was coming and that it would be the oil pump. The source didn’t seem very solid, someone knew someone at Toyota they said was a good source. Not saying that is correct just passing along in case someone is interested.

 

that wouldn't surprise me either, the low pressure reading has concerned some for a while now, there was a TSB about the gauge, etc at one time I think as well.

but the speculation wagon rolls on.

what perplexes me is IF this problem is bad enough to warrant a design change , that seems odd to me given so few failures overall.

 

Toyota V35A Oil Pump
Yes, the Toyota V35A-FTS engine uses a variable oil pump. The pump is chain-driven and features an electrically controlled solenoid valve that regulates oil pressure based on engine temperature, speed, and other parameters. This system allows for variable oil flow and pressure, improving efficiency and ensuring adequate lubrication under varying operating conditions. The pump's operation is managed by the Engine Control Module (ECM), which controls the pump via an oil pressure control valve to maintain optimal pressure

This all just sounds like a really bad idea to me, and I agree, it's all emissions and fuel saving related. The engineers are trying to provide the bare minimum oil pressure that they *believe* will be adequate, all to just save a little bit of friction losses from maintaining constant oil pressure??? Someone needs to write a Forscan for Toyotas that allows users some control over this nonsense and just let the damn oil pump, pump oil.

 

I firmly believe that just about all new vehicle problems are caused by all this Cafe and emissions bullshit.

I don't want to get the ban hammer so Im leaving politics out , just talking regulatory wise.

 

It's been happening since the mid '70s when the EPA began regulating emissions under the authority from the Clean Air Act, and it's been getting worse ever since.

I'll never forget when I first looked at my Father's 1982 Jeep CJ7's engine. I had a 1979 CJ5 at the time. I could not believe the maze of hoses, sensors, switches, wires, and other crude emissions contraptions in my Father's Jeep compared to mine. It was like I was staring at a different engine even though they were both the same 4.2L I6 engines.

One of the most popular modifications on those '80s era CJs, with all the problematic emissions crap, was called the Nutter Bypass. It bypassed the crude computer and all the trouble-prone emissions systems by cutting and splicing 2 wires. There's probably only a handful of CJs on the road that still have that garbage in place and operational.

 

Nope.

And let me guess, it was in the 2023-2025 Toyota Tundra Owners group?
