[@tootall5559]

to get a degree, all automotive engineers should have to work as a mechanic for four years or so before they're allowed to design a damn thing.

[@drmodestoesq]

Ah....but you're forgetting about the problem evil and greed. What if the mechanic knowingly designs the engine to fall apart right after the warranty expires in order to make him and his profession a lucrative income?

[@tootall5559]

@@drmodestoesq you think they're not already trying to do that? I swear they have program in the computer that tells the car when it's out of warranty and then the computer acts up and makes the car quit. At least if they had to do the work, they would probably make it at least easy access so they could turn a buck faster. I used to own a damn Chrysler the actual book on changing a starter was to pull the engine. I didn't of course, but I did have to loosen them up and jack the motor up a bit to wriggle the old starter out and the new one back in. That's just ridiculous to pull a motor to change a starter, especially on vehicles known for being hard on starters. The real Dodges, made by the Dodge brothers, had a noiseless starter. Some had starters that were starters when they needed to be, generators the rest of the time. All the so called advancements they have these days ain't shit.

[@drmodestoesq]

@@tootall5559 And why are the dealers up in arms about Tesla selling cars without the dealership model? Because instead of a car with 250 moving parts in the drive train and electric car has one. Well, that's probably a slight exaggeration but you get the idea.

[@tootall5559]

@@drmodestoesq Tesla may have well it's got to have more than one moving part... no way it can only have one and have four wheels... anyway, Tesla's are not all that. They take a long time to charge and really don't have all that much range for the time it takes them to charge. When they can get 4 or 5 hundred miles on a charge that takes about the same amount of time as it does to fill your tank, then they'll have it. The battery tech probably exists, but the oil companies keep it under wraps. They've gone so far as to buy out companies with any advances and then destroy the company, and any of the existing batteries.

The number of times we've had to tell 'architects' that their ideas were never going to work but were overruled by managers because the 'architect' has a higher level college degree than us programmers, only to be proven right that it was never going to work and then being blamed for 'not implementing the design properly' are legion.

[@CU08]

Nah, the engineer and the assembler are on the same team. It's the beancounter at HQ who looks at the plans and scraps most of them as being too expensive and puts it all together with the cheapest parts bidder available. Especially with GM of this era. Literally every car they put out in the early 2000's was absolute garbage. It's amazing that anyone buys their vehicles after being exposed to the absolute shit they made ... and mostly still make.

[@johncahill3644]

I was in a consulting situation when GM approached us with an early design problem for the Northstar (somewhere around 1993). Their issue was that plastic springs in the upper heads were vibrating through the magnesium valve cover very quickly (like in 24 hours!). They had used (heat-resistant but highly abrasive) glass-filled nylon for these springs and came to us for a better design (as we were the material supplier). My immediate take on it was that they were missing the bigger problem, that the plastic springs would relax over time (and not be springs anymore). I told them to rethink both the nylon springs and the magnesium valve cover. They resisted and paid one of my more eager colleagues $100,000 over a year to fix the issue (only to ultimately discover that yeah, the idea wouldn't work). Northstar sucked from the beginning, like most half-@ss GM designs. Maybe we should talk about the Quad4 plastic intake manifold next...

Many years ago a team were taken to the manufacture of emergency equipment. One demonstration that day was a new emergency flare. To cut a long story short it was a brilliant example of design. Compact and just so easy to use. One of the team went off and brought back a fire bucket (this is in winter) and asked the design team for a volunteer. One stepped forward, at which point they had their hands shoved into the bucket. After 10 minutes, they had their hands taken out and were given the flare to fire. At which point they could not even get through the wrapper, never mind actually use it. Lesson: design as if you're the person who will have to use it. Too many times car and engine design is predicated around the installation on the track, not down stream maintenance six years later.

[@TyphoidMarypatrick]

I'm not even sure it was a cost savings issue. I think some freshly minted young engineer specced the bolt and threads without regard to the materiel the block was cast out of. A steel bolt into a wrought or forged steel part is usually going to have the bolt be the weakest part of the fastener assembly. For this, fine threads are advantageous because it increases the minimum cross sectional area of the bolt, meaning the bolt is stronger. Fine threads actually have more holding power (in steel), but in aluminum it's a weaker fastener because even though the bolt itself is stronger, with fine threads it reefs the female threads right out of the base material. I think where the GM-itis is with the Northstar is that when they started having issues, instead of fixing it properly by using LS7 studs or revamping the northstar design to use larger coarse threaded bolts, they bandaged it with the threadserts to fix the issue just long enough for the warranty to expire.

[@d46512]

@@TyphoidMarypatrick Thank you for weighing in with an informed expert opinion. I didn't know the age old debate, fine vs coarse actually depends on the material. Can you explain what would have been a more robust alternative to a time-sert? Not familiar with LS7 head studs. Don't you need to repair the stripped block first?

[@TyphoidMarypatrick]

@@d46512 well for new production they could have revised the block castings to accommodate a better fastener, and to fix the already produced one, recall for a drill and tap job like in the video. It would have been brutally expensive but probably not too much more so then the timesert installation and you wouldn't have a fleet of cars blowing head gaskets and pissing off owners.
