Yes, engine should turn with car in park (you start em in park....)
No, you can't bumpstart an auto (bad idea to tow em more than a mile or two as well unless you take the prop off)

another thing with the diesel engines is there often based on existing petrol designs and to get the compression required and make full use of the longer burn of heavy oil the stroke is increased, thus normally adding 100-300cc but generaly not a nice whole number. which leads to things like the bmw m20b25 and the m21b27 (b number is the capacity m number is the engine type, in this case its the same engine with a long stroke and funny head) i mean who the hell sets out to build a 2.7 litre engine?

Some autos cant be towed at all with the driving wheels on the road and connected t the box depending on how the box is configured internally, refer to your owners manual is the answer I'm afraid, also you can tow start some autos but you have to get em up to 30mph or so and its not always succesfull, far better to jump start the car, if it wont start on a jump then fix the reason for that first.

I have a REALLY daft question... Who the hell did I sell a set of 17" steels to, late last year? They were on my truck before I fitted some billet Alloys (and sold the truck). I used to know where all my bits 'n' bobs went - this is really frustrating me!

That certainly sounds plausible we did that in A level physics with an ali tube and a magnet. One way and it drops straight down normally. The other it will generate eddy currents in the ali that oppose the magnets fall meaning it takes about 10 seconds to fall through rather than 1. I wouldn't of thought it would of provided enough force to slow down a truck but if the magnet is powerful enough I guess it would. This sounds to me like you're describing a Retarder. A lot of buses and coaches have these, and I assume trucks do as well. The retarder as I know it is some kind of electro-magnetic brake, which is normally used to lengthen the life of the normal brake linings. On automatic buses, these are often built into the transmission in some way, and is activated when you press the brake pedal lightly (i.e. before the wheel brakes actually engage). They are normally more useful on automatics because there isn't as much engine braking, although they are fitted to manuals as well. A lot of modern coach retarders are quite powerful. Some have a small lever so that you can control the retarder by hand. On one of our Volvo's, you can pretty much bring the coach to a standstill on the retarder alone. They are also useful for descending long hills with heavy loads, as you can slow the vehicle down with the retarder and save boiling the brakes!! IIRC it was originally called a TELMAR retarder, brought into use in the 60s after several bad coach crashes where the brakes failed on hills

Re INERTIA fuel cut off switch, A steel ball held in place by a magnet on a spring plunger, enough inertia to move the ball from the spring breaks the magnetic hold on the plunger and the two part company and break the circuit, [most of the time] I ended taking mine out of the cortina, giving my car welly and the ball would come off its seat and cut fuel long enough to drop the ECU, then as the car slowed slightly the ball would reseat, and we would be off again, bit of a Kangeroo style of driving, Fookin PIA

If i recall correctly i've heard/read somewhere that it says in older merc manuals that they can be bump-started if towed fast enough.

^ I heard that too, it's the basis behind the urban myth..
Stranded motorist with auto car asks passer by with truck for help, explains that he needs pushing up to 30mph as car is an auto, truck driver nods, reverses up the road, then drives into car at 30mph....

OK a question from me:- How much -ve camber can you get away with (for road use) before:- a) you actually make matters worse and b) you star wearing tyres out at an alarming rate? difficult question as it depends on car and sus system, and ones in particular? I'm thinking Morris Minor and torsion bars I can answer this if you like. There's no realy way to know for sure without accurate computer modelling. An educated guess depends on the OEM positions and any modifications. Generally lower and stiffer allows more static negative camber but I have no idea of the suspension layout of a moggy. As a rough rule of thumb I wouldn't add more than about one third/half a degree negative (assuming a fast road set-up, as apposed to trackday, race, rally etc).

I have a daft question! ;D Can you Mig weld stainless steel with wire intended for mild steel? I need to repair my stainless exhaust box which has split due to clouting speed bumps - but I don't want to buy stainless wire (if such a thing exists) for about 3" of weld. I don't really care about losing the stainless qualities of the exhaust box as it really needs replacing! cheers folks

Yes, normal mild steel mig wire can weld stainless perfectly....but (as you point out) the weld will be liable to rust. Not really an issue by the sound of it.
Just treat the welding the same as you would with mild steel.

ooo. i think my b4 passat has one of those blocks. makes sense cos its got a rattly diesel

Can someone please explain the exact purpose of these mudflaps? the Mini has such a short front overhang that if you go headlong into a large puddle the wave pushed forwards and up isn't normally stopped by anything and will fly up into the windscreen if you're going quick enough, dramatically limiting vision as it's usually muddy puddles, with grit in...

Great, cheers mate! Wouldn't have guessed that.

Range Rover Classics are the same, no front overhang so when you hit a puddle the water goes straight up and you drive into it, not that i would use a Rangey to go charging into massive puddles just for a laugh of course.

Any problem replacing 45W bulbs with 60W? It's for an AX. The fuse seems to be 5A so 60W should be too powerful or am I wrong? I tried them and it works but I've got a country drive during the night tomorrow and don't want to take risks. But the extra light would be welcome.
