I think that what SM25T describes is quite common. This was recently discussed here, but for open nuts. There is a rule of thumb that engaged thead length should be a minimum of 1.5 x bolt or stud diameter. (For closed nuts there's also the potential problem that the recess isn't deep enough for the length of stud.) Jonathan

Is there another indicator on the same side of the trailer? Check feed voltage at the towbar socket (while the indicator should be on). If that's OK check feed voltage (while the indicator should be on) at the lampholder, and earth from the lampholder by continuity testing. Jonathan

Water sitting in the plug recesses? There were a couple of reports of this, but I don't know which engines are susceptible. Jonathan

A cousin has a bike for sale. Dorset DT11. If you're interested please send me a Private Mail including your email address, and I'll put you in touch. "It is a full carbon fork & frame, Cannondale Synapse 105, 2010 Size 51 cms, sloping top tube, so probably suitable for 5ft 6 to 5ft 8 rider. The bike is in great condition, running as or better than new, it has triple chain rings. Price around £800." Jonathan

I've always understood that torque settings should be reduced (by maybe 30%) if the fastener is lubricated (say with copper grease), on the grounds that applying the specified (dry) torque would likely cause over-stretch. The important point for end users like us is that you don't change from the conditions used when the torque settings were specified and expect the same setting to remain appropriate. Changes that could affect the appropriate setting include lubrication, materials and fasteners such as washers. When I first used 75Nm, the next time I came to take the wheels off, a few of the nuts were alarmingly loose - barely more than finger tight! Since then I have gone to about 85Nm and not had the same issue That's very unusual. I'd have a good look at both threads. Open or closed nuts? What sort of wheels? How much stud do you have protruding from the hub? Jonathan

I've never had a problem (although it does remind me of an old joke). But when you say "bolts"... what's your set-up? Jonathan

Can I use a CBS 48 led light on my positive earth car just by "swapping the wiring"... From the pictures on their site it looks as if it has a two-core fly lead and you could just swap them. Jonathan

15 minutes, but that was an expert: instructions here. Jonathan

Have you got a photo of the chairs, please? Jonathan

If anyone else manages to mislay the washer bottle cap this one fits the bottle in a 1998 K. It even has a retaining ring to make it slightly more idiot-proof, although, as I now know, that term is only relative. http://i.ebayimg.com/00/s/MjAwWDIwMA==/z/DCgAAOxyKh5SALTO/%24T2eC16Z,!)EE9s2uiNc(BS!LTOckRg~~60_1.JPG Jonathan

The temperature protection against concentration is in this data sheet. The manufacturers recommend deionised water. I don't have any data on this but I suspect that many owners use tap water without any bad effects. The Haynes manual for the Rover engine doesn't mention the need for deionised water. Changing the coolant frequently is a good idea. Jonathan

Hmmm.... no bright ideas other than an insert. But there were some experts discussing which type for which job a few months ago... should be in the archives, and I think it included something about routine use in aluminium... Jonathan

Thanks. Do you have access to the other surface? Jonathan

I'm impressed, and hope your head won't be. :-) Jonathan

Could you add a photo... might give a few more options. Jonathan

Near Polysemy? ;-) Jonathan

:-) I must keep up! Jonathan

revilla's excellent analysis of what was happening with at least one Brise starter. Jonathan

On the upside I now have a ball bearing throttle pedal pivot, altered cable angle for improved smoothness, twin cable linkage and a new found willingness to have a go at most jobs on the car. Excellent: there's not enough zeugma on BlatChat! Jonathan

That Pipercross cleaner and oil kit is £13.86 including delivery from Caterham Parts, and £11.69 on eBay. Jonathan

What's the nominal size of the new one that doesn't fit? Jonathan

IIRC WD-40 is as good as proprietary removers... Jonathan
