Are the engines pre-broken in or not?

HAHA! That totally made my day, didn't even notice, good eye, sir!

 

Yep. Ones I am around do aviation parts.

 

Open your owners manual folks. It covers addresses the need for break-in. If Toyota thought it wasn’t important, they wouldn’t have spent the $0.01 on the extra ink to talk about the issue in every single manual sold w/ each truck. If changing your oil early warms your nuggets, than do it

I’m a structural engineer. Believe me, you’ll see it on the news if we fuck something up. There’s a good reason we’re all licensed.

Even still, accidents happen. I started my career in construction before going back to school for engineering and I learned early on that there are many, many people along the way to completing a project that can/will fuck something up for the end user. You’d don’t have to be an engineer to be one of those folks. Hell, I'd argue most good designs are thoroughly fucked by the bean counters on the project.

Haha I used to rip on the "dirt guys" until I started studying for the PE. Now I just rip on the unlicensed guys

 

Well that certainly explains all the posts over the last few years complaining of Toyota engines constantly blowing up by not changing the oil at 5k miles.
BTW, your frame will turn to rust long before the wheels fall off....remember: Rust Never Sleeps

 

ok, serious question. Just for discussion purposes. How many miles should you put on a Tacoma before towing a 2500 pound trailer?
Ready......Set........Go..........

 

trick question! no tacoma or toyota has the towing capacity of something ThAt HeAvY!

 

The Aholes at the docks brake them in plenty.

 

I miss the days before the Internet when there wasn't the ability to fret over shit that doesn't matter. Back then we just drove and enjoyed our vehicles

 

I like this and generally tend to agree but in this case, I'm running out of time. My truck is due to the dealer sometime between today and Monday. I'm leaving for vacation on Thursday, with a boat behind me. I'm just curious how many late night drives I need to take to pack on a few miles before hitching up.

 

Good point about construction can cause accidents, Hyatt Regency walkway collapse is one famous disaster that comes to mind.
While being a licensed P.E demonstrates a certain level of knowledge it doesn’t stop mistakes from happening and Id rather have an independent review any day than rely on a single Engineer with a PE stamp for critical high risk designs.
Disclaimer: I am a P.E. Lol
P.S. Totally agree bean counters are the most dangerous individuals to any project

 

Some engineer or engineers let the 3rd gen transmission firmware have a pass. It was good enough they figured and they need to get out on their Ranger boats for the weekend that were likely towed by a Tundra.

At the end of the day they all didn't graduate from the top of their class, have the same work ethic, for some it's risk vs. reward and some are under the gun to just push shit out like Windows Me

 

Unfortunately engineers work for Managers and CEOs often make decisions and requirements that engineers have to meet, and influence them in ways that can end in a poor product or even end in disaster. For the Tacoma it was a few tenths more MPG in the EPA tests vs good performance and MPG won. Guarantee that wasn’t an engineers choice.

 

Ok, so why was it necessary for the RC-62F equipped 3rd gens to go FAST in reverse?
I'd love to ask the engineer(s) responsible for that one lol

 

The pud knockers at the top aren't into the weeds or on the tools, if some bumble fuck can tune these trucks working out his garage, Toyota could have done better. The fact there was an update to the trans firmware showed that they weren't doing enough testing in the real world.

Should have kept the 4.0 if it was good enough for the 4Runner it's good enough for the Tacoma. I'm sure it looked great on paper and on numbers. We don't have to teach Karen and Kevin to assemble the 4.0 they can just build the same engine we stick in the Highlander, Sienna and Camry. The one engine fits all approach, a play from FCA.

 

You really think engineers make the decisions as to what engines to put into which vehicles? In my job I’ve seen managers and directors jump right down onto the weeds, hear a little information and make “management” decisions that are opposite of what we engineers would make.
You have a good point on the tuning issues though, engineers could have done better.

 

Well, at the end of the day the company needs to make as much money as possible right?
That's what the "suits" are paid to make happen.
I'm not saying it's right, just a reality.

 

I think the manual says 500 miles before you tow anything. Something to do with drive line and break in.

 

BMW suggested long oil drain intervals...it cost customers big bucks!, but I do agree that the oils have improved hugely, I'm sure the car manufacturers would love for us to buy another vehicle within 3 years or so.

 

Ah the Hyatt Regency collapse - that whole shitshow almost turned me off to structural engineering in school.

With that said, I totally agree w/ you regarding the independent review. Our firm actively pursues 3rd party review on our critical designs and we perform the service for other firms in the area (ha I'm having flashbacks to some of my first seismic designs). More eyes on a set of calcs, the better. I still have quite a few friends in the construction business, so I'll usually hit them up too to see if they see any big constructability issues while we're in the review stage.

I don't know that other industries have 3rd party review like structural engineering does - I'd be curious to hear about how that works from folks in the ME fields.
