comment Tools needed for smooth Subaru head gasket job
Yes, the full system of coolant comes out the exhaust pipe within 30 minutes of driving. :-) When the leak was less serious I used a sealer product and it held for about 6 months, then progressively got worse to this stage.

comment My brake fluid all left on short notice. What gives?
If the fluid level got really low, you probably have air in the lines now. That would explain the softness and need to pump.

comment Why are drive by wire systems so unresponsive?
@Paulster2: An encyclopedia is never a valid reference, wikipedia or otherwise. However a proper encyclopedia cites references for all the non-obvious facts it includes, so you simply go to those sources for your citation.

@MDMoore313: No way, print encyclopedias were even more error-filled, biased (with different biases), etc. Wikipedia is a big step forward, but like all forms of democracy it requires vigilance to make it work.

@MDMoore313: That wikipedia article reads like a manufacturer's advertisement for the "feature"; someone should really fix it. Especially the claim of increasing safety is preposterous.

comment Getting the best results sealing head gasket leak with Blue Devil
For what it's worth, I need to revisit and update this answer. After 6 months it started failing, and by now it's undrivable. I've read up a lot more on the chemistry of HG sealing products and I'm left pretty skeptical that there's any benefit to the more expensive ones. I also don't think my guess at how it worked before fully makes sense, so I'd like to make a new shot at trying to explain it.

comment Extremely high then fluctuating idle at very cold temperatures
I've seen this symptom in various vehicles, but not temperature-dependent, where it was the IAC valve. I seafoamed my IAC valve in the past 6 months mainly as preventative maintenance, and it doesn't have this issue under normal temperatures, so I doubt this is the issue.

Very interesting. I hadn't even thought of this possibility. If you or anyone else can find a reference to substantiate this I'll consider the matter closed and accept this answer.

comment Juddering under load
Cleaning the idle air control valve might solve it. A decent cleaning can be performed with seafoam (spray version) without removing it, spraying into it from the throttle body next to the throttle plate.

comment How far can you drive with an empty radiator?
Keep in mind my comment was qualified with "if the weather is cold enough that freezing is a concern while the engine is running". I'm not actually sure how cold it would have to get for that to be an issue, so maybe I'm wrong, but my (reasonable, IMO) guess is that it's so cold that you'd have significant heat transfer rate from the engine block to the ambient outside air, regardless of any internal air in the system.

comment Is idling bad for your engine?
I would expect that running the engine at idle (no load except its own internal friction and accessories on the belts) puts a lot less wear on it than running it under load. "City miles" are not just "worse" in that there's wear that's not reflected on the odometer, but also in terms of load starting from a stop, varying throttle (with moments of suboptimal gas/air mix), etc. So I don't think this answer really settles the issue of how "bad for the engine" idling might be.
