My favorite data structure is the k-d tree.

comment Found this in my wheel
At first glance, it looks like a rotor's dust shield, but the picture is pretty unclear. Can you light it a bit better? Also, what do you mean by "inside" the wheel?

comment Batery is above 12 volts but car ignition fades
Get the battery load tested. It may be the right voltage but not be putting out enough current.

Is it possible for you to just air it out for several hours with the doors wide open?

"Oily coating" to the tires? Do you mean wax? Oil destroys rubber.

comment Nuts for 2008 VW Jetta SE 2.5L battery terminal bolts: 1/4" or M6?
Sounds like the pitch of the nuts you bought is wrong.

Does "heatbox" mean "heater core"?

comment Toyota Celica battery light on but alternator appears okay on visual/auditory inspection
Where are you getting your figure of 13.8v as the maximum charging-state voltage? It depends on the car, but that's near the minimum of what any functioning alternator should read -- at least a volt above the battery's nominal 12.6. My car's alternator is specified by the manufacturer to run in the 14.1 - 14.8 range, depending on temperature. Going over 13.8v while charging does not necessarily indicate a problem.

comment Can faulty O2 sensor cause omission check engine light?
Other things besides emission problems will turn on the CEL; without knowing what the code actually was, it's impossible to say why it turned on or off. (Also, it wasn't your timing belt that was replaced, as Paulster noted on your other question.)

Here's a pretty clear picture of the setup: subaruforester.org/vbulletin/f66/…

comment Vibrating sound and shaking when turning the wheel after changing timing belt?
There are two "accessory" belts on this car; if the arrows are pointing to the rear one in the picture, then the belt was for the A/C compressor, not the power steering pump, which is to the (car's) right of the alternator (just visible in the top left of this picture). The front belt drives the P/S and the alternator, and has no separate tensioner; the tension is adjusted via a bolt on the alternator. It's possible (even sensible) that both belts were replaced at the same time, but if tensioner was involved, that was the A/C belt's. @KingsInnerSoul

Also, if the cat failed within a year, something else is with your engine. I've heard people implicating failing head gaskets for that.

That's definitely the right ballpark. Catalytic converters are expensive. I'd think you could get a cheaper sensor, but I'm not positive.

The diagnostic code will indicate which it is. You should be able to get it read for free at your local parts store. There should be, as far as I know, three sections to your exhaust: first section includes the front cat and sensor, second section the rear pair, and the last goes back to the muffler. Unless somebody did something weird: my Forester had a piece of pipe welded across what should have been the joint for the two rear sections when I got it, so when I needed to do the rear cat, I had to do the end pipe as well.

Note that there's two cats and two sensors; you should double-check which are problematic.

comment Are there any double-DIN bluetooth stereo system that can connect to multiple devices at once?
The problem is that the result of "Are there any Xs that do Y?" and "Which X should I buy?" is the same: a speedily-obsolete list that's also a potential spam magnet. I don't think there's a good way to ask this on a Stack Exchange site.

comment Correct procedure and cost repair BMW timing chain (BMW 318ti)
My point in my comment -- which I don't seem to have expressed clearly -- was that there's no inherent reason for the previous owner to have replaced the chain at 86k. Thus, it's indicative of a possible problem, something the purchaser should be aware of and maybe investigate for related issues.

comment Correct procedure and cost repair BMW timing chain (BMW 318ti)
I don't seem to have spoken clearly. My thought was not that you should worry about replacing it again, but that there may be an important reason, which you need to know about, for the previous owner to have replaced the chain. There's no reason -- again, AFAIK -- under normal usage for him to have needed to do so; thus to my mind it's a suspicious detail in the car's history. There could be other problems that are related but either latent or just plain unfixed.

Find out why the chain was replaced. As far as I know, a BMW's timing chain shouldn't generally need replacement anywhere near 86k.

comment What material should I look for in an oil drain plug gasket?
The job of a washer that doesn't deform is just to spread load out over the workpiece. I don't know if that's necessary, and in any case it would only happen if the washer's outer diameter is larger than the plug's. Out of curiosity, what metal is the current washer?

comment AC Recharge- What did I do wrong?
This answer is not particularly useful given that the OP acknowledged in the question that DIY A/C service is generally fault-prone. The question asks specifically what the fault might be in this case.
