What's new

engineering that makes you want to punch babies.

Watching this guy describe the Special Service Tool setup for correctly setting up the timing and installing the valve springs on this BMW I8 is pretty cool. He reviews the tools, sets up the engine, then uses the tools. The tool design, construction, and use is straight up tool porn. He starts around 6:42 - 7:50

Then skip the commercial to where they do the install, as it's a really cool setup. He puts the pin in the flywheel to secure it at TDC (although it turns out it also has the pin hole at 180 off that and has to go back and redo it later) and he uses this sexy as hell spring installation tool at 15:50 - 16:55.

Seriously, I can't even imagine trying to install those springs without that tool and it makes it looks super easy when done with that setup.

I have learned to buy the tools.

they're not hard to service when you have the right tools.

which is why if this motor ever pops it just gets another, cause there's thousands of dollars in special tools to put one back together.

does anyone need to borrow a $300 suspension bushing tool?
used once.
 
That's not a cheap job. :eek:

He's got a lot of cash in the specialized tooling alone. He made good on the deal though because nobody could sort out the overheating problem which turned out to be a bad head gasket and the dealerships wouldn't touch it unless he agreed to a full $10k engine swap out. He told them to pound sand, tooled up, got an ex-BMW tech who knew his business and got it done for under $6k. He's cleaning it up and flipping it, so he's going to come out pretty good on the deal.

I wouldn't touch an I8 with a 10' pole myself, but it's not a bad deal if you've "got a guy". Everyone needs to have a guy who knows his business and will do it for a reasonable price. I like to wrench on projects, but with some of these modern platforms, it really pays off to have a factory trained tech run the job.

Now that I know you have one....

lets you do the tension arm bushings on the car so you don't have to fuck with the balljoints.

also lets you squeeze the M3 bushings in there with some slight modifications to the bushing shell.
 
The rear control arm nut at the frame on a jeep wj Grand Cherokee has a nut spot welded to a metal tab that does absolutely nothing except try to cut your fingers off when you use an impact on the bolt. Also, because the nut is spot welded to the metal tab on each of the flats you can't get a wrench all the way down onto the nut, making it easy to slip off. That tab does nothing, it isn't a flag nut because there is nothing for that tab to go onto, and there is no reason for it as there is plenty of access to get a wrench on it. 2 minute job ended up over 1/2 hour! Ain't nobody got time for that!
 
Recently I had a pleasure of changing out an alternator on a ‘06 Sentra (on the side of the highway for extra points).

Pretty dang tight in some spots to get at the bolts - for one of the alternator bolts I had to use two boxed end wrenches (different offset on each), one to get the bolt started and other to finish it with.
Geniuses at Nissan put catalytic converter / heat shield alongside this area. No room to get socket/ratchet/extension in there at all.
Belt adjustment bolts were an afterthought as well. In comparison Honda/Toyota are much easier to service in my experience - fk Nissan.
 
today in hitler's revenge, sunroof drains that get clogged by a single leaf and ruin hundreds of dollars of electronics in the back.

Let's design a sunroof that doesn't seal, then will put a dam around it with four 1/4" drain tubes. What could go wrong?

Fun part is when you're blowing out the tube and you get a dust cloud going inside the cab. Then you have to take down the headliner and fish in new hoses to replace the shit rubber ones that have dry rotted. While you're at it you might as well replace all the vacuum lines on the engine too.
 
I just did the correct fix to my jetta's hole in the roof only an idiot would choose to equip their car with
urethane caulk

1st gen Tacoma rear O2 sensor... connector is inside the cab... and cable tie is on the top of the frame... 1” between frame abs body.
And body mounts.. why are 14mm bolts needed? Treaded from the top down? Pita.

unfortunately the fatherland hates north america and you could not buy a wagon without the sunroof.

because americans are dumb I guess. I fucking hate the thing. it's noisy, it's now leaked, it takes away like 2 inches of headroom and it's heavy.
fucking stupid.
 
Refrigerator access behind the shitter is shitty.

America's taste in long roof vehicles is shit.

That's possible.

I don't work for BMW, but I can tell you for sure that a lot of people at VW HQ in the US are looking at many metrics in order to come up with whatever option/feature combination that will sell the most in the USA and will make the most money for the company.

We've discussed carbon fiber pieces to replace it already.
 
I came up with a new hatred.

My wife thought we should buy a camper, and found a cheap one on the Facebook.

So far I've spent more time fixing it than camping, and I'm hoping she loses interest and sells the damn thing before long.

Everything I touch blows my mind. This thing is supposed to be towed down the road, and it's put together with toothpicks and dreams.

They call them "Sticks and staples" for a reason.
