comment 92 Civic engine won't start after replacing head gasket
Well done. A compression test should be able to tell you if there is any damage (and if you can change a HG, a comp test should be a piece of cake for you), but a blowing exhaust and corroded plugs will definitely sap power. 90 degrees out is quite impressive though, I'd have thought that if it were an interference engine that's be enough to totally destroy the valves...

comment Peugeot 206 LX (2002), I have installed a cd player which works but it doesn't remember volume/clock settings
I think they're in the right place, just the wrong colours. Green&Yellow, for example, is the European standard for earth cables for mains wiring, so I suspect that is their logic for using it for ground cables in a car (despite everyone else using black or brown...) No idea why they're using sky blue for power though!

comment 92 Civic engine won't start after replacing head gasket
A timing problem can very easily cause a lack of compression, so that's probably your first suspect. Hopefully you didn't hear a nasty clattery noise the first time you tried to start it (valves open too late can easily hit pistons and bend...)

That's what standards are for isn't it ;) At least they've fitted the right plug...

I believe so - I think all new cars in Europe have had to have ISO connectors for the past decade or so.

comment Is it possible to lock wheels when ABS is working?
Brian, ABS isn't indended to lower the stopping distance - it is intended to help you keep steerage control while stopping, thus giving you the chance to steer around the hazard.

comment Oil spray against rust
IIRC Waxoil do two versions, either the thicker paint type that hardens, or a thinner oil that doesn't harden, but needs to be re-applied each winter

comment Does torque decrease mathematically?
Not necessarily, it would depend on things like the gear ratios, the size of the wheels, the torque curve of the engine and quite a few other factors... Torque as a number is purely a measure of how much turning force the engine can produce. It also depends on what you mean by faster - top speed or acceleration?

comment Does torque decrease mathematically?
I don't get what you're asking? Neither power nor torque bear any relationship to the vehicle weight, hence why we have a "power to weight ratio" so we can more realistically compare two vehicles.

comment How dangerous is it to carry oil/gasoil/gas at the back of one's car?
Siphoning fuel from your tank to power another device may not be such a good idea, as many modern cars now include an anti-siphon device in the fuel filler to reduce fuel theft. I'll agree with the rest of mike's comments though. Most filling stations (at least round here) sell approved containers for around the price of a gallon of fuel.

comment How can you tell the oil needs to be changed?
While this link may answer the question, it is better to include the essential parts of the answer here and provide the link for reference. Link-only answers can become invalid if the linked page changes.

comment Manual transmission at stop: 1st with clutch in, or neutral with clutch out? -OR- Throwout Bearing wear
+1 for using the parking brake - This also has the advantage of not dazzling the drivers behind you with your brake lights...

Have you checked the transmission fluid level?

comment Is it normal for the oil to be dark in color right after an “oil change” in a 10-year old diesel car?
Yeah, but it is fairly easy for an unscrupulous garage to clean the dust, oil etc off an old filter, hence adding a more permanent mark...

comment How to find ignition wire on mercedes truck
As the other reply says - check with a multimeter first to work out which is which! Looking at the link you posted below, I would expect the PSU to have two inputs, one expecting a permanent live feed and one taking a switched feed, so that it can send the 'power off' signal to the motherboard when you switch off the ignition. It'll draw more current from the permanent feed, so make sure you use a good feed, separately fused, for this.

comment How to find ignition wire on mercedes truck
Ah, in that case you want to look for the signal wire going to the stereo - Yellow according to the proper ISO colour code, but again this may very according to manufacturer. The best place to look for that would be behind the stereo.

comment How to reduce engine drag
If your car cannot maintain a constant speed with light throttle pressure, you are in the wrong gear. When you lift off the pedal completely, the car will decelerate through engine braking - If the car automatically disconnected the engine you'd lose the engine braking! In fact, in some jurisdictions, it is illegal to drive with the car out of gear (or the clutch held depressed) as you are not considered to be in full control of the vehicle

comment I bought a new radio. How difficult would it be for an amateur to install?
The one on the left, with a plug on one end and loose wires on the other, is the type described by Rory in his answer. The type I mean has a plug on both ends, with one end matching the stereo and the other end matching the car.

comment Sound system volume fades in/out erratically
The general rule of thumb tends to be "would you take it to a mechanic or automotive specialist if you couldn't fix it yourself" - you would with an electrical problem so I'd say this was on topic. I've added 'radio' and 'audio' tags.

agreed - check the fluid level quickly!
