comment Do pistons keep moving when the car stops?
You can of course do it manually with the key in older cars, but whether it's worthwhile depends on how efficiently the starter can restart the engine. I suspect newer cars with this feature have the necessary sensors and variable-output starter needed to turn the engine with the minimal necessary electrical power so that you don't lose all your savings from the alternator recharging the battery.

comment Should Multiple Coolant Hose Leaks in a Short Time Worry Me?
If the system returns to normal pressure after cooling down, this is unlikely to be the problem. A HG leak doesn't always mean you'll see oil transfer, though.

comment Shutting off fans at highway speeds
Interesting. If that's the case then you actually want the fans to be "always-on" at speeds above ~35mph so that you can harvest the generated power (to take load off the alternator) rather than wasted, right?

comment What are the Advantages & Disadvantages of a Boxer engine?
If you want to see the disadvantages just try changing a head gasket (or rather 2 head gaskets). Or even just changing the spark plugs... ;-)

comment What are the Advantages & Disadvantages of a Boxer engine?
@IhavenoideawhatI'mdoing: it's a key part of their AWD design, and the low center of gravity is probably nice for the handling/feel of the vehicle.

+1 this is a great tip in general even if it doesn't apply to OP's specific model.

comment Tools needed for smooth Subaru head gasket job
@seth: As for the torque wrench requirements, I'd check the head bolt tightening instructions to be sure about what you need. It's been a while and I don't remember the details right off. I lacked the right torque wrench for the crank pulley nut, so I just took at as far as my torque wrench could then gave it a heavy yank with an ordinary wrench and my "breaker bar" that's just a long (about 4 feet?) pipe that fits around the wrench handle.

comment Tools needed for smooth Subaru head gasket job
@seth: I didn't have the flat ratcheting wrenches for the job, but I think the size that would have helped the most was around 10mm, for the valve covers. My basic toolkit was a full set of regular and deep metric sockets up to 17mm, open-end and 12-point plain wrenches in the same sizes, screwdrivers.

comment 2 Volts on Car Battery
@Nick: Most batteries I've purchased have pro-rated warranties even after the full warranty expires. You might be able to get a replacement for only 30% or so of the cost if it's just a few months out of warranty.

comment Is shifting to neutral on a decline more fuel efficient than keeping the gear engaged?
OK you got me there. I agree my comment isn't relevant as an answer.

comment Is shifting to neutral on a decline more fuel efficient than keeping the gear engaged?
I don't think it's quite so clear-cut. Unless the hill is steep enough to maintain speed with the transmission engaged, you're going to have to give it fuel to maintain (or get back up to) the desired speed. There are plenty of situations where coasting can maintain speed but engine braking can't. I suspect you're still better off engine braking than coasting with the engine idling, but if you shut off the engine while coasting, coasting is the clear winner.

comment Why don't car manufacturers treat rust-prone parts of a car with rust converter?
Rust converter is a treatment that reacts chemically with rust. It's not a preventive measure except insomuch as, by eliminating existing rust, you prevent it from spreading. Other preventive coatings are already used where appropriate.

comment Front left controller arm corroded and broke on my 2002 Hyundai Elantra
In terms of danger, you've probably understated it. Without the control arms in the proper place, the axle CV joints can come apart; at even moderate speeds their components are potentially dangerous projectiles. I had a separated CV joint blow a hole in an oil pan when it popped out of place. As long as there's not more damage the LCA should not be an expensive repair (I'd guess $70 in parts and 1-2 hours in labor) but please get a tow to the shop.

comment Extremely high then fluctuating idle at very cold temperatures
Thanks. My car's intake system does not appear to be that advanced (separate valves/regulators), but it seems plausible the ECU could be controlling the IAC valve to get this behavior intentionally.

Craftsman and Gearwrench now both have versions with an open-ended ratchet on one end. No idea if it really works.

Yeah, I really think I should get some of those. Do yours have the open end ratchet too or just the flat socket type?

Other head came out easily too. Posted an answer with info on additional tools I used or would have liked.

comment What to do with damaged alignment dowels in block?
It came out easily with vise grips and some gentle turning back and forth. Got the heads machined and almost ready to put it back together. :-)

comment What to do with damaged alignment dowels in block?
Thanks. I just got back from the Subaru dealership with a replacement part (for free, even) and the technician who helped me there basically confirmed what you said, and also that the new part can be hammered in with a block of wood. As for the head, I don't think it's damaged from the pin, but I suspect it may be a bit warped and I'm going to get it checked out and possibly machined.
