I think the cheese-metal carb screws are intentional, tbh. The carbs are made of very soft cast aluminum or zinc, and even a tiny crack will ruin them, so it's better to strip the screw than risk overtorquing and breaking the carburetor body. I think. e: but yes definitely some of the reputation comes from using Philips bits on JIS screws. They are not truly compatible with each other and the difference in shape will exacerbate the Philips' designed-in tendency to cam out and strip.

That being said, the drivers for either will work with either. You do have to be careful with a phillips driver on a JIS screw, as they tend to chew them up in short order. I actually prefer a JIS tip for phillips head screws because the non-cam out action of the JIS tip gives you a touch more purchase on the screw.

Not common, but not super rare either, was the car that was towed in with the dash lit up like a christmas tree because someone had kicked the ECM connector hard enough to knock it loose.

I still think the award for worst ECU placement goes to the Isuzu D-Max/Holden Rodeo with the 6VE1 3.5L V6. Heat? Check. Vibration? Check. Premature failure? Check and mate.

I dunno, early 90's, I think. When they went to the style with the electronically controlled injection pump. They put the controller on the engine and, what would you know, they have issues with all those things! There's actually a factory relocation kit for them...

It would make it easier, but you can get access by just removing the boot on the side of the airbox where it connects to the fresh air intake. I always remember hating that thing, though, because you had to push and turn with a bellows duct against a flexible hose to put it back together, so it was like pushing one rope with another rope.

Dagen H posted:Issue #1: they're JIS. Get yourself the right tools for the job. Yeah, I know that now. 15 years ago when I first got it and started fixing it, I had no idea JIS existed. Why in the gently caress would you use a fastener head type exclusive to your country for a machine destined for export? Anyway, thanks to the impact driver, I'd wager that they're loving Phillips now. Thanks for reminding me to buy some JIS drivers and bits, though, since I have a whole pile of Mazda RX-7s and the AE86 that undoubtedly use them. Dagen H posted:JIS screws have a little dot on the head: Thanks. Did not know that. Also, apparently, while a Phillips will gently caress up a JIS, you can safely use a JIS driver on a Phillips. Geoj posted:That being said, the drivers for either will work with either. You do have to be careful with a phillips driver on a JIS screw, as they tend to chew them up in short order. Well, there you go. Well, now, this is interesting. This article says that JIS is extinct, quoting Vessel as saying so. Not sure what that's about.

Dagen H posted:JIS screws have a little dot on the head:  I had no idea. Are they all like that? Talking about soft bolts, ditto on the old UJMs. I once rounded the bolt head for the oil filter housing on my old Honda CX500 and I ended up saying gently caress it and kept the same oil filter in it for about 2 years before I got around to taking it off. I don't know what the hell they were thinking with those fasteners made out of surplus aluminum foil. I didn't even tighten it hard.

spog posted:How do you pronounce 'JIS'? It's "jay-eye-ess"  And one of the pieces of equipment I work on (Fuji DEVO) has T7 screws with reduced head depth. They strip so easily, the first instruction in the manual for removing the back cover is "order 20 new screws." InitialDave posted:Allen heads are the devil's work in anything needing more than minimal torque. Head depth matters alot too. Euro manufacturers love that poo poo though. The best is american companies who engineer all their machines to use SAE screws then use an OTS European or Japanese component that has Metric screws, and is secured by metric screws.

One benefit of allen head is that you can also use the pound-a-torx-into-it-to-get-it-out method after you completely strip it.

Simple leverage tells you the further out from the centre you apply your force the better. Also I found a new use for 12pt sockets, they hold square nuts nicely. As to why I'm using square nuts? Well I have no excuse there, they're crap.

If you use the right size 'screw', that wouldn't be too bad. Worst crime is building a device that requires screwing at an angle to reach but is designed as a flush mount. Tons of railings do this.
