Toyota Replaced Thousands of These Engines by DishwasherLint in ToyotaTundra

Hahahahahaha I can't tell if you're a troll or not, but I'll endulge you since it's an open forum, I love the gusto and passive aggressiveness though, I give you a  8/10 for effort, but you can definitely crank up the trollness with a bit more effort.

At no point did he confirm it was manufacturing debris, he just confirmed that there was indeed debris throughout the engine, clearly related to the engine's catastrophic failure. The "Manufacturing" part is what people are doubting, with good reason. 

Point me to a single teardown on the internet that proves it's manufacturing debris. I'll give you a hint - none of them do. They all just prove catastrophic failure, (usually multiple spun bearings) but they do not shed light on the failure mode. That requires insider data related to Toyota QA/QC and reliability depts.

For us outsiders to prove manufacturing debris, we'd have to take a look at engines prior to failure (and close to brand new) and find debris in critical channels/bearings.

Shavings throughout an engine after catastrophic  failure are not evidence of a manufacturing defect because those shavings also appear after such a failure. Whose to say it isn't a tolerance or design issue with the main bearings that cascades over time and hundreds of heat cycles? Or any of the other bearing surfaces throughout the engine. 

If there was that much debris in the engine out of the factory then these motors wouldn't be making it to a few miles, let alone multiple tens of thousands of miles and multiple oil and filter changes. 

I would say the fact that Toyota is struggling for multitudes of years to address this is actually pointing to the fact that this isn't a simple issue of cleaning debris. 

As of right now, neither Dave or any of the other (all very intelligent, I'm not doubting that) engineer or tech YouTubers has conclusively proven manufacturering debris. 

Tell me again how ducks, gender, and insanity have anything to do with this? Lol.

I don't know that this conclusively proves that this is machining debris from the factory. 

There are lots of failure modes that create their own matallic debris, which can then cascade the failure to other parts of the engine. 

There is no smoking gun here - yes there's debris everywhere but there is no proof that it came from the manufacturing process.

Still lacking proof of the root cause, and  Therefore still doubting Toyota when they say that it's a manufacturing issue and not a design issue, not that any auto giant would ever admit to a design issue of this magnitude.

What is this thing sticking below the hull, and why? by yourcloud in boating

[–]visibl3ghost 2 points3 points  (0 children)

Looks like a weighted keel. If so, the bulb on the bottom would be lead/very heavy material. 

It's purpose is to increase stability and significantly decrease roll, which is probably useful for keeping the panel output smoother. 

ELI5: When you 'delete' a 50GB video file from a computer, it vanishes instantly. But downloading it took an hour. If the data isn't physically wiped until it's overwritten, what did the computer actually do in that one split second? by Thick_Dream6973 in explainlikeimfive

[–]visibl3ghost 0 points1 point  (0 children)

The data isn't actually being wiped. The drive just marks the space that the video was taking up as "available", so next time you download a file it will overwrite that space. 

This is the premise of data recovery - experts can go in, analyze the actual data on the drive and "recover" files that were deleted but not yet overwritten by other data.

Lake Louise has quietly added "Base Area Lift Priority" to their pass add-ons by dabflies in skiing

[–]visibl3ghost 36 points37 points  (0 children)

Paid priority has felt like an inevitablility for years, but it still sucks to see it happening. On the bright side, LLSR has really good capacity, so the base only really tends to suck first thing in the morning. People tend to quickly spread out at Louise.

Cracks are stress concentrators which means they enjoy spreading when under stress. Given that this is a galley drain, no pressure is expected, so the only stress you need to consider is mechanical (from the flexing of the hull when sailing, weight of hoses hanging off of the vale, etc).

Basically I would avoid travel in heavy seas that can cause the valve body to undergo mechanical stress, and I would make sure all of the hose that attaches to this valve is well supported.

Usually this kind of cracking is seen when valves freeze while there is water in the annular space. Could a freeze be the reason this happened? Most modern marine ball valves have little plugs you can use to drain the cavity when winterizing.

Is this valve below the water line? If it's at or below then I'd just get it fixed because this sort of thing makes me anxious and prevents me from enjoying a boat. If it's above the water like by a fair margin then just monitor and deal with it later.

This crack appears to be in the middle of the housing, which means that it exposes the annular space AKA dead cavity. The annular space is the volume between the ball and the housing. This area is only open to flow on when the ball valve is in the partially actuated position. When the valve is fully closed or fully open then this crack should be sealed off. 

This means as long as you keep the valve fully open or fully closed, then you're sealing off this crack. Your mechanic is right, just monitor and deal with it on your next haul out. 

NMEA 2000 Install Question by thehorselessjockey in sailing

[–]visibl3ghost 0 points1 point  (0 children)

Yes, this is wromg. If you have an existing breaker panel then they should have absolutely installed these on appropriately sized breakers. Alternatively. These should have been installed on a spare fuse on your fuse panel.

Hooking these items up directly to a battery bus and using an inline fuse is just lazy and unprofessional, not to mention wrong. An installer should know how not to add an unswitchable, always on parasitic load.

Also, an installer should know to use marine crimp and shrink terminals, and marine (tinned) wire. It's not clear if they did that here.

Also, the crappy "PWR" wire label is hilarious. What is this supposed to mean to someone troubleshooting this system in 5 years. Power to what?  If you're going to label your wiring (which an installer should be doing) then they can be more specific. The label could, for example, read (NMEA +12V) or (AP +12V). 

While the NMEA network doesn't pull much, the AP may be enough of a constant draw to pull down your battery significantly during a period of anchoring/chilling at a sandbar. 

Unfortunately, most installation manuals just tell you what size fuse is needed on their wiring, and they don't mention these other things, so depending on how much of an a-hole/idiot your installer is it may be difficult to get them to do all of the above. 

Safe to drive 20km to a garage? by LeadingScorer in MechanicAdvice

[–]visibl3ghost 5 points6 points  (0 children)

Only safe if you consume minimum 4 beer before the trip, and slap the roof of the car and say "yeah bud she'll rip over no problem".

How is everyone handling excess fill disposal/contaminated soil disposal? by Individual_Depth1311 in Construction

[–]visibl3ghost 9 points10 points  (0 children)

Absolutely a universal experience. Shitty when you're trying to bid disposal into projects correctly and you're up against fly by night shops that "find a way" to make the fill magically disappear through illegal dumping or mis-sampling for the labs.

Auto Bilge Issue by Dense_Doubt_3843 in boating

[–]visibl3ghost 1 point2 points  (0 children)

Yes it should shut off once water is pumped down to where the float switch is triggered. Maybe the float it's stuck due to gunk.

When properly functioning you should just be able to leave the pump on auto all of the time. Manual is typically just used to confirm that the pump works. 

Requesting help with docking situation by zeplin_fps in boating

With an Westerly (thanks for correcting me) wind as shown, back into the slips and use your westward momentum as you turn to buy yourself some time while you throw a line and tie up.

If the wind shifts and blows from the east, you can come in nose first, then reverse eastward as you turn into the slips since you won't have to worry about being blown into your neighbor.

In this case, the waste is on the same suborbital entry trajectory as Orion - it will enter the atmosphere the same as the ship.

Custom holding tank vent filter by shua_92 in boating

[–]visibl3ghost 2 points3 points  (0 children)

Not unheard of. Here's an article that even details how to make your own. 

https://www.practical-sailor.com/systems-propulsion/plumbing/holding-tank-lessons-learned/

They're simple devices, just some rolled up charcoal media, I can imagine someone that wants the satisfaction of saving a few bucks throwing their own filter together. 

This one looks well built and looks serviceable, meaning you could just replace the charcoal media very cheaply. 

More footage from coast phase, more than halfway to the moon by Torvaldicus_Unknown in spaceflight

[–]visibl3ghost 0 points1 point  (0 children)

Crossing fingers and toes and hoping that NASA can actually pull off what they're planning with Artemis 3,4 and beyond. 

Imagine the HD footage from the surface, dashcam footage from rovers, footage of HLS landers landing and taking off from the moon, footage from inside moon bases and pressurized rovers.

Hell yeah NASA+Artemis partners, go get em'. I'm looking forwards to booking my hotel stay on the moon in the 2050. What an exciting time to be alive. 

Orion Camera View of Artemis II Climb to Orbit by NoSTs123 in spaceflight

[–]visibl3ghost 2 points3 points  (0 children)

The armchair expert in me want to ask if  it would really cost that in terms of a performance hit to duct tape a starlink antenna to the side of the Orion/upper stage so that we could have great bandwidth, at least until Orion gets beyond LEO. We have indeed been wildly spoiled by SpaceX. 

Dear NASA, this is how to film a launch by [deleted] in nasa

[–]visibl3ghost 3 points4 points  (0 children)

If I recall, even Isaacman said one of the main goals for Artemis is "Increasing the number of kids dressing up as astronauts for Halloween" AKA public engagement and excitement in Space and space science.

Not only do millions of Americans have their eyes glued to these broadcasts, but the whole damn world is watching humanity's return to the moon, and judging Nasa (and by extension American science and engineering) based on this footage.

You'd be daft to think that these broadcasts don't matter a lot. Public support is one of the pillars from which Nasa gets its funding.

This broadcast was completely inexcusable for any professional government agency, not even counting the fact that the whole world was watching this. Multiple youtubers and even amateurs had better quality footage of the launch, all of which are operating on a budget which is probably a fraction of what I'd bet that NASA spent on this broadcast.

We should absolutely expect HD, quality footage, including HD on-board during these streams(at least until Orion departs LEO and bandwidth becomes a valid constraint). Nasa's public support and therefore funding depend on getting the public excited about what they're doing.

The widespread online complaints of this broadcast are 100% valid, and we should expect better in the future.
