agreed - check the fluid level quickly!

comment how a car engine can get accustomed on some behavior?
Indeed, this then leads to the concept of the 'Italian tune-up' - giving an under-used car a good blast to clear out all the deposits that have built up. This is especially true of a car that does lots of short journeys, as deposits build up more if the engine does not have a chance to warm up properly.

comment What may be wrong with my central locking?
It could be that the signal wire going to the right front is broken - i.e. both front doors tell the system to open, but only the left front and right rear actually work. The right front is only unlocked by the mechanical linkage from its own keyhole.

comment In what order does it make sense to upgrade suspension components?
I agree. The other advantage of having a second set of wheels is that you can switch back to your normal road tyres before leaving - very handy if you're at an abrasive venue and have trashed the rubber you were using!

comment Proper Jack Location
@Patrick - the tyre trick is also useful when changing a tyre 'in the field'. Sling the new wheel under the car while you remove the old one, and vice versa.

comment Advantages of getting your car's oil changed at the dealer
I would add, avoid anywhere that leaves oil on your seats or carpet - that just reeks of a mechanic who doesn't care about the job he's doing!

comment Oil change with front wheels on ramps?
You'll never get all the oil out anyway - a lot of it is left coating the innards of the engine! I'll second the "don't worry about it" comments.

comment C-clamp stuck in brake caliper
You do indeed have air in the system - air compresses fairly easily, so as you have found, you don't get any pressure. Yes, I would recommend getting a specialist to bleed them, if you are at all unsure about what you are doing - get them to check over the rest of the system as well to make sure it it all safe and secure.

comment Nissan Pulsar ST1.8 oil filter change
@Krom - No, oil filters should only ever be done up by hand, and the OP has said he can get a hand on the filter

comment C-clamp stuck in brake caliper
Be very careful not to snap any of the bleed screws in the process - they can easily sieze and break, which will wreck the caliper. A small quantity of penetrating fluid can help here. I'd also sling that c-clamp and get a new one, it looks fairly ruined!

comment C-clamp stuck in brake caliper
Ok, so now you need to clean up the exposed part of the piston, then carefully wind the piston back in (using, as you noted, an old pad to protect it). Refit using the same pads as the other side (i.e. new if the other side has new ones), then fully bleed the system.

comment Horn / hooter works when car is off, not when car is on?
aah, the old bodge trick... In that case, look for traces of hacked-together wiring to see if you can work out what he did to it, and you'll probably find it has been connected in the wrong place - You might find it easier to rip out his bodges and re-do it properly, rather than trying to diagnose what changes he has made...

comment How Does a Person End Up With Their Timing “180 Out”?
The thing to remember is that one cycle of a 4-stroke engine takes two revolutions of the crankshaft (and thus the pistons), but only one revolution of the camshaft. Therefore #1 piston is at TDC (closest point to the spark plug) twice in the cycle, and you need the spark to occur the second time - at the end of the compression stroke.

comment How to generate involute gear milling Gcode
I can't answer the question, but just remember that if the gears are to be used in an automotive application, they would need to be case hardened - this process causes the metal to shrink, meaning they have to be cut slightly larger to end up the right size. I've heard it described as "an art, not a science"!

comment Squeaky steering?
PAS fluid is something that is changed, but on a much more infrequent basis - more like brake fluid. Your car's handbook should tell you where to look, there should be a small cap somewhere in the engine bay you can open and check the level of the fluid inside - the handbook will also specify the type of fluid to top it up with.

comment What parts are required to replace a clutch?
I've only ever had the first three listed items in a clutch kit. Alignment tools aren't that expensive though, and as you say, they're a reusable tool.

comment Wear on inner of rear tyres
Cost is very dependant on where you are. In the UK, I'd estimate it at around £20-40 per corner for standard springs, plus half a day or so labour, and £20-40 for alignment - probably somewhere in the region of £2-500 total. That is assuming your dampers are in good condition - if they are old it would be worth replacing them at the same time to save on labour costs - add another £30-40 per corner at a guess. You could do it cheaper by buying secondhand springs, but only if you are confident the source can be trusted.

comment Power vampire in car. Where do I start looking?
It is generally best to disconnect the negative, as this removes the risk of a loose positive cable touching any part of the (negative) bodyshell.

comment Just HOW urgently should I replace this tire? Is it safe to drive on at all?
@Bob, that is the point I was trying to make - a full size spare is just as good as any other wheel, but very few cars in the past 10 years or so have had one.
