I find it hilarious how people run around criticising soviet tanks for lack of crew safety and other stuff like that but somehow 1 in 4 chance of death from using the death prevention device is totally ok.

Apparently there isn't. I saw a documentary which looked into it and they couldn't find any evidence of such laws anywhere. It's usually corporate policy, made under the false assertion that such laws exist.

Not quite. Most parts retain their existing fastener type and size until they are phased out, and/or are chosen by whatever company designed that particular part of the car. Which is why you get weird poo poo like:
- on a jeep 4.0L, every single bolt threaded into the block itself is SAE, because it was an ancient 258ci i6 dimensionally on the outside. But every single bolt threaded into the intake manifold is metric because it was redesigned in the 80s for the new motor. Except for the pipe threads, those are NPT because we're in America god damnit we don't want none of your loving BSP or metric straight thread + O-ring nonsense.
- all the bolts holding the bellhousing to the engine are SAE because again, it's designed to fit where a 258 did, EXCEPT the two crank position sensor mounting bolts which are metric (and have an 11mm head!) because that was introduced with the EFI system at the same time as the new intake manifold etc.
- the bolt that goes through the starter into the bellhousing is SAE, because the bellhousing pattern is again, the same, and SAE, BUT the bolt that goes the other way through the bellhousing into the starter is metric, because they introduced a new starter at the same time and it was made by Nippon-Denso so it's metric.
- the studs that hold the (metric-native, designed in the 80s by New Venture Gear) transfer case to the (metric native, designed in the 80s by Aisin Warner) transmission are all SAE, because the pattern was pre-existing and each side of it was designed to be compatible with earlier components.
- All the body hardware is metric EXCEPT the things (like fuel tank J-bolts, connector hold-down bolts, and selftapping sheetmetal screws) that were borrowed from existing products or were standard hardware purchased in the states for assembly and were therefore cheaper to get in SAE than metric.
- all the nuts and bolts in the axle assemblies are SAE because they were existing legacy Dana/Spicer designs from previous decades, except the suspension link hardware and anything related to the calipers and unit bearings, which were new designs and thus metric.
- the steering box has SAE bolts holding it to the frame, a metric pinch bolt keeping the steering column shaft hooked to it, metric O-ringed hydraulic fittings, and an SAE thread on the sector shaft to the pitman arm, because it was designed by GM to work with existing chassis parts, but new body and powertrain equipment.

I think my favorites are the two starter bolts and the tcase to tranny pattern. They really throw people off.


Seriously? That's hosed. I've never seen GM do that (sure seems like they stick with metric for everything I've worked on except SBC stuff), but Ford I wouldn't be surprised by. The Rover hermaphroditic bolts amuse me every time you mention them.

As for horrible failures, here's a 1/4" wall frame rail after a friend's flywheel exploded and went right through the bellhousing, since it was just cast aluminum:

Front of transmission:

Clutch and transmission input shaft:

Everything else:

looking up from under the truck before the engine was pulled: (if you look up from where the flywheel should be, you will see the clutch disc and what's left of the pressure plate!)

Aftermath in the engine compartment: (hi again, clutch disc)


Total damage list:
engine block
crank
bellhousing
input shaft of transmission
everything inside the bellhousing
exhaust
fuel lines
brake lines
frame rail
a 40" offroad tire
the impact at the front of the transmission was so severe that it broke the transmission tailhousing in between the trans and the transfer case, at the back of the transmission
wiring harness
firewall
the DBW throttle pedal

oh and a big chunk of the flywheel hit the asphalt so hard it was embedded 2" deep.

Most concerningly, it set the leaking fuel on fire and destroyed the throttle pedal while he had it floored, wearing only tennis shoes. He walked away without a scratch.

When he rebuilt it, he put an SFI rated blowproof spun steel bellhousing in for some odd reason.

Yep, that's the big six bolt pattern from 2.5 ton rockwells not the little one from yota and half ton chevy/FSJ axles. He probably snapped the kingpins or knuckles, that happens when you abuse those axles too much.

As for ripping off the chassis... time to find a YouTube video

Walked into my mechanic a couple of months back, he's my bosses brother so I kinda trust him. We saw a couple of huge slicks sitting in ther corner, I asked him about them. Turns out they aren't slicks, they came off the back of an X5. The owner so was shocked that 335 35 r20 (?) cost HEAPS even when you buy lovely Chinese knock offs she balked at replacing them. She was failed on local inspection and had to replace them. Imagine her repsonse when he suggested the fronts were also terrible and they needed replacing too...

I think someone on these forums explained it prety well - An X5 is an aspirational car and now people who are wrapped up in "I own a BMW X5" can own one for cheap. They just don't understand that the luxury car that makes them look like they own the world on the school run comes with high service costs.

People mock me for my 20002 grandma Corolla. Guess what, I can afford it. And the service costs.

Probably old age, maybe abuse or a manufacturing defect.

Radiator hoses are basically made in three layers, a bit like tires: an water/air-tight inner liner, a structured carcass that supports the hose against internal pressure, and an outer protective layer. If the inner layer is compromised because of old age, abuse, or a defect, then pressurized coolant will work its way through the reinforced carcass and create a bubble under the outer protective layer. That outer layer isn't really designed to hold pressure, so it'll eventually burst, but in the mean time you see that huge swollen bubble.
