comment Bent front fork on a bike
Personally, I'd steer well clear of it - if you know it has been in an accident and not repaired properly, what other damage might have been caused and missed? cracks in the frame etc...

comment Petrol vehicles, what are the advantages and disadvantages of a turbo charger?
@RoryAlsop Most UK market Diesels I can think of from the last 20 years have either been turbocharged or had a turbo option, except the smallest hatchbacks...

comment How to avoid having air bubbles in clutch line after cylinder replacement?
One trick I was once told - If the master and slave cylinders are both accessible from within the engine bay, attach a length of clear pipe to the slave cylinder bleed nipple, then stick the other side into the master cylinder reservoir, so that the fluid being bled out of the system goes straight back in, but without the air bubbles. Much less wastage... (Don't do this on brakes though, for safety reasons, and logical ones...)

comment Risks of “excess and lack” of Engine oil
If it is being burnt, it means the oil is getting past some of the seals, into the combustion chamber (cylinder). This means the seals are worn out. It's usually the valve stem seals that go first. Whether these can be replaced without dismantling the engine depends on the engine.

comment Risks of “excess and lack” of Engine oil
The oil sits in the engine sump, and is picked up by the pump, which forces it, under pressure, around the various moving parts of the engine, such as bearings and camshaft

comment Risks of “excess and lack” of Engine oil
The answer to "how long it will bear it without oil" is zero. The wear will start instantly - even in normal operation, the vast majority of the wear of an engine occurs in the couple of seconds it takes for the oil to start circulating properly.

comment Is it common for ECU's to maintain individual limit maps for each knock sensor?
The temperature profiles of each cylinder will be ever-so-slightly different too - the ones on the ends of each bank will have only one adjacent cylinder rather than two so will be a tiny bit cooler... They'd also be affected by differing coolant & lubricant paths and other items in the engine bay. I can't imagine it'd be a big enough difference to affect anything though - probably not even measurable with normal equipment!

comment Can I use a different size donut spare tire for my 97 Accord?
@NateEldredge indeed, that's why the donut spares always carry a "no more than 50mph for 50 miles" or similar warning, to reduce the risk of damaging the diff...

comment Can I break power steering by turning too far
Indeed - the handbook for my current car specifically says "Do not hold the steering wheel at full lock for more than 60 seconds as this can cause damage to the power steering system" (or words to that effect)

comment Noise when the engine is idle
This isn't really about maintenance or repair... That is normal behaviour, it is because the gearbox is turning when it's connected to the engine, and not when you disconnect it by pressing the clutch...

comment Adding aftermarket backup lights
As it's a pick-up, I'd stick a pair of LED work-lights on the back of the cab. That way, you can use them as worklights when loading and unloading the pickup, and as extra reversing lights when needed. I'd have them on a separate switch on the dash.
