comment At what level does low oil prevent vtec from working?
Does vtec use an electrically actuated valve? I thought it was entirely based on oil pressure.

comment Why does my car sometimes blow cold air while the heater is on?
I suspect newer vehicles with thermostat-based climate control systems may shut off the heat when the AC is on, except of course in defrost mode. So this answer seems at least plausible.

Am I correct assuming you're talking about the situation where the transmission is in park?

comment Hyper-miling and stress on engine oil
Replacing oil is dirt cheap; determining if you need to costs a lot more, in terms of lab work, than just replacing it.

comment Brake fluid reservoir level drops fast to minimum but not below
Another possibility is that you just have a lot of air in the system (failure to properly bleed it). This happened to me - brakes were "mushy" and I kept "losing" fluid with no visible leak. Eventually, after enough top-offs, it stopped happening and the brakes got firm.

I've done this mod (just removing the belt) on an 88 Civic with no ill effects.

comment Easiest way to disable the A/C compressor
For a compressor, it's almost certainly not cheaper to replace the whole thing; just the cost of vacuuming out and refilling the system will be higher than the cost of the pulley.

comment LED tail lights flashing at ultra high speed
What kind of car was that, and are you sure? It's possible there are some really old, or non-mainstream-consumer vehicles which use 24v instead of 12v, but 24v output from the alternator would boil off a normal car battery in no time...

comment LED tail lights flashing at ultra high speed
The voltage in a car is always 12-15 volts. Any LED unit made for replacing automotive lights is going to expect this voltage, and I would guess they use a DC-DC converter to get a stable output voltage for the LEDs, though other approaches would also be possible.

comment LED tail lights flashing at ultra high speed
Huh? There's no reason to think you should need resistors between the LEDs and the power source to avoid burning out the LEDs. The correct solution is either to replace the flasher unit with one made for use with LEDs or replace the LED unit with one that goes out of its way to waste power and heat up the flasher unit like a normal incandescent bulb would do.

Apparently OP has the replacement and knows what it looks like, but can't find the old one in the vehicle.

comment 3 Questions related to fixing/replacing 2005 Toyota Prius bumpers?
Yeah, I'm aware of the general warnings, but found it odd that the bumper would apply. If removing and replacing the bumper puts you at risk for airbag deployment, I would think bumping another vehicle in a parking lot would be equally risky, and much more dangerous to the driver and passengers, since the seats are occupied.
