So, please, can our senior experts give us the benefit of their WTorque magazine, the last of which was published in experiences over the years, preferably in the form of Torque articles? autumn 2011. A lot has happened since then – especially to our cars. But, seemingly, not always written about! Please Now technology too has changed dramatically since the days of Jensen then, may I make a plea for you to give me some more Motors Ltd. – and not least with the advent of different compositions technical articles for a future Torque magazine? and grades of petrol, and a whole world of bewildering choices of lubricants. These do, of course, suit the modern car, but may not I try to put a variety of articles into the magazine, so that there’s always suit classic vehicles; hence the article from Chris Reed re something of interest to everybody. This issue hopefully satisfies the Engines and Oil Engineering, to try and help you find the correct oil for more technical requirement. your particular car and the way that it is used. Note that what would suit one Interceptor may not suit another – it depends greatly upon Torque magazine is intended to help pass on information between their engine’s condition, and how it’s used and the car driven – so JOC members so that everyone can benefit from hard-won knowledge please read the article thoroughly! – and sometimes bitter experiences too! The JOC Technical Advisors also play a role in this, and we should certainly make use of them if And if someone out there is able to write a definitive article about the we need help and advice. widespread use of Ethanol in our petrol (I gather that some super unleaded brands may have a minimum amount of ethanol in them The absence of a factory to issue Service Bulletins and updates is, already), what damage they may be doing to our cars’ engines and of course, sorely missed, as shown by all the data and information fuel systems, and what we should be doing to minimise that, then contained within Richard Calver’s Service Bulletins Vol. 1 (2004), please get writing! which makes fascinating reading. It certainly shows that you cannot rely on the Workshop Manual and Spare Parts Catalogues alone!

I suppose a long time ago, (when garages each other as much as we can. This isn’t always easy – and a little had grease bays and the like,) that each organisation had at least one knowledge can often be dangerous – and certainly one only has to suspension expert who would know from long experience how to set read the JOC Forum to see the occasional differences of opinion that such up properly, and the tricks of the trade. But now? Much of that often ensue (in the absence of the factory to issue official guidance knowledge has gone – unless owners and clubs such as the JOC keep based on correct engineering design, engineering knowledge and it all alive and updated. principals, engineering development and product testing). Otherwise, it’s back to trial and error again, which is always, always We do tend to learn by trial and error. So anything we can do to share very expensive... that knowledge and experience has got to be a good thing. So please – get writing! And here is a plea. We have a mixture of old and new members. Many of the older ones know the tricks of the trade, and have indeed already gone through the learning curve with their cars; they may even assume that newer members are equally aware of such.

Inside you will find many articles of interest. From an article on Just Married horns to one on oils, we can all learn something new. Torque is something that is a little extra for you the members and, as originally intended, it is a compilation of technical articles to help and assist you in keeping your car(s) on the road. We have all at one time or another looked at a particular task and thought ‘How will I ever do that?’ Some things are quite easy to take apart, but it is slightly different understanding how that part should work, or indeed how it all goes back together again. I wish I’d had the article on the Interceptor window frames to hand recently, particularly the bit that mentions looking at the spacers before you Our congratualtions go to the happy couple of Alex and Rachael take it apart... Waite – the lovely Interceptor convertible is owned by Alex’s father Mr Douglas Waite (photos courtesy Joab Woodger-Smith) The reason you haven’t had one of these magazines for a while is simply down to a lack of technical articles. The Editor has been working on this magazine for a while and despite many repeated requests for articles with photos I know he has had to persuade, cajole and plead. If you are contemplating doing a task on your car, could I please ask that you write it down and take some photos. Your article could be the next one to get published and will help a great many others My thanks go to Paul (the Editor) for his perseverance in making this magazine happen and also to those of you who have sent in articles.
