I think it is a couple of engineers collective sense of humor showing through. However, it provides more coverage than the windshield wiper system they were using before it.

It's the engineering equivalent of dick-waving.
Just like the cast-aluminium removable tow hitch on my Audi, there's no point in it except to show off design skills, which I guess they chose to do because you can't really show-off the aluminium suspension components
easily.

Failure modes don't differ if the external loading is the same. The amount of load applied to cause failure will be different if all else except the material is kept constant. I'm sure that aluminum Audi tow hook was designed with a generous factor of safety.

well not really, higher grades of aluminium start to become brittle even though their yield strengths are vastly higher (some cases nearly 2x) to your run-of-the-mill carbon steel. Aluminium on the whole is also more prone to fatigue based failures

Aluminum is more prone to fatigue as it's nominal (Engineering) stress is lower than steel, and that is also lower than it's yield stress. Aluminum's yield stress is higher than steel generally since it is more brittle (it has a larger region of elastic deformation with respect to strain), but it's ultimate stress (the point at which the material breaks) is lower (because it's more brittle, which basically means it does not like plastic deformation as much).
That is not a difference in failure mode, that is a difference in material properties. If you axially load a bar, it's still going to snap more or less perpendicular to the loading axis.
Science bitches. :science101:

Well, engineering science.
It disgusts me as to what these filter companies and quick oil change companies do.
My SUS had an oil change ~500 miles ago at a 5 minute oil change shop.
They used an M1-108 filter, with 10w30 Castrol Edge.
The issue?
The 108 is a Honda filter. It is nearly half the size of the OEM Subaru one, and has a 13PSI bypass vs the OEM 23PSI.
Mobil 1 Recommends 108 filters for many Subarus, even though they don't meet OEM specs and are tiny.
The Edge oil; It's okay oil, but was overfilled by 2 quarts.
I changed it out for a Bosch filter (right size and bypass PSI) and Rotella T5 10w30. Car runs much better now.
Well yea, the only way to turn a profit on something as small as an oil change is to cut corners and get sleazy on shit. Its a completemy fucked industry that just shouldnt exist at all.

It's even more disgusting what Honda of America has done with their filters, the original PR3 filters designed for the B/D series platform have been superseded at least 4-5 times and now they have a one size fits all filter made by Fram which is a basic orange can Fram filter with a silicone ADBV and a better relief spring as well as a slight mod to the filter media to make it less shit. Those filters aren't good enough for the military either as they even use the higher quality Filtech power equipment filters which are a 15400-PLM-A01. However despite the A01 still being produced the A02 Fram can is the only one usually stocked. Every other country and market uses either the Filtechs or Toki Rokis. Only the NSX and S2000 still have filters made for them but the NSX was recently discontinued and the PLX S2000 is probably soon to be. I've recently switched to Bosch as the have a good cheap filter with a silicone ADBV with a design that is plenty good. The Mobil 1 filters overall are overpriced and not that great of a value.
I'm curious what Clutch uses for his NSX since from what I remember it was a bitch to find NSX application filters. Denso was making a proper NSX filter which was supposedly nearly identical to the Toki Roki filters but they recently just moved to China and their filters were all just redesigned.

The OEM price is twice that price, just for the head gasket.
Replaced my alternator and charged the battery in the Impreza and everything was great, until I realized the headlights and foglamps are dead. Turning signals, rear, everything else is fine. Fuses look good, dunno about the relays or bulbs. Is this a familiar problem to anyone?

brap.
Chicks, cops, and old people digg it.
Vacuumed all the rat shit out of the car and kicked out the remaining field mice. DP kindly gave us a huge bag of shop rags which we had to bury because the stench of rat piss was overwhelming. Sorry DP. :(
Purged the chocolate milk from the oil bath air filter and found all the parts to hook it back up to the engine. Catalogued remaining parts. Tried to cheap out on weather stripping, turns out it doesn't fit. Accidentally vacuumed up a live mouse but it was OK because we also accidentally vacuumed up a shop rag immediately prior to that which saved it from certain death.

What a piece of crap. That bumper made a hole in the floor.
Still not sure what the hell did that. The floor pan is sharply indented from beneath up into the cabin, it's about 4 inches above where it should be. The passenger seat is sitting at a weird angle as a result. Only thing I can think of is the car must've been dropped on a jack stand or something and it punched a hole in the floor. Luckily it didn't fuck up the frame.
So I went to the track and because of that, my front right tire is now corded. A couple guys and I didn't expect that small flat spot to become so bad. In search for a new tire now, hoping I can grab a new set of fronts from a friend he doesn't need anymore. Hoping to save up for maybe re-71rs next year, but not too sure.

This axle is weird.. doesn't seem to match the VIN lable. I dunno, I don't see many '70s or '80s Toyota SRAs with the removable rear cover on the axle. It's usually serviceable with a removable front pinion assembly. Hum.
So, now we have the shocks out and all the nuts loose on the control arm bolts. But take a wild guess if those control arms will come out. If you guessed "No fucking way in hell" that would be correct. Maybe with a bluetip wrench, but that I don't have. The bushing sleeves are all corroded to the bolts.
So I started with the Sawzall.

I used 1 blade per bolt.. not bad. They're still "good" but with grade 8 junk who wants to start cutting with a used blade? These are hopefully the only 2 sawzall cuts, the rest I think I can get the grinder in on with the cutting disc. 18 cuts total, if only 2 were going to be sawzall slow, I'll take it.
A buddy made this 'concept art' in Forza. Pretty close...

you need to look deeper than just "snapping". things can snap the same but be characteristically different, which comes down to its material properties yes, which goes back to my main point that different grades and different treatments can vary a material wildly, even simply where it was manufactured.
[QUOTE=The Decoy;51210531]Do diesel injection pumps knock if bled dry?[/QUOTE]
The diesel fuel is their sole source of lubrication, so it can damage them to run dry for extended periods.
But it depends on the exact type of diesel injection pump
