Re: E-type market - are cars selling?

I really don't think that the engine change is likely to be a feature which makes the difference between a sale or no sale, although it might make a moderate difference to the price achieved . There is a fair amount of uncertainty about at the moment , and perhaps more to the point the big supply of...

Re: E-type market - are cars selling?

My trade contacts seem to think the market for all classics is quite difficult at the moment . This seems to be borne out by the number of unsold cars there have been at recent auctions, and E types in particular seem to have been quite hard hit . I think patience is called for . Certainly, the wide...

Re: Sweating Brake Fluid Hose

I think Steve is perhaps being pessimistic : provided you do not operate any part of the system while you are changing the hoses, you should not introduce air to the high pressure part of the system. So , siphon the old fluid out of the reservoirs and the down pipes one at a time, change the down ho...

Re: S1 4.2 Diff noise

Very likely indeed to be the diff . You need to get the rear cover off and see the marks on the crown wheel which show the tooth engagement. If you look in the knowledge base in the final drive section of the workshop manual, it has useful diagrams showing the significance of the tooth marks ( you p...

Re: Duff VR?

You need to make sure what it is which drives your ignition warning light . Some were relay driven from the charging system , but there was a period from about 1965 on ( end uncertain ) when the "ignition" light was actually operated by an oil pressure switch plugged into the right hand gallery just...

I never have been able to find out why Christopher and his friends have had such horrible luck with the 123.

Re: The Great MoT Confusion

AFAIK, all you have to do when the MOT has run out but there is still a period of "Tax" extant, is to declare the car SORN , and then next day tax it again. You should then get the option to declare the car exempt from MOT

Re: Ported vacuum advance vs manifold vacuum advance

At 800rpm, you probably only need to open the throttle butterfly by about 800/6000 of the full 90' movement to let the engine pull in enough air for 800rpm running, so wide open throttle means just that at 6000rpm but it also means anything over ~20% at the lower end of engine speed is as good as w...

Mark S : if you mean by not turning easily that it is lumpy to turn round, that is exactly as it should be. It is an AC generator and the lumps you feel are at the point of maximum magnetic interaction between the poles and the armature . With your fingers a good wristy twist will not produce more t...

Re: Ported vacuum advance vs manifold vacuum advance

U get the most torque if the explosion is just as the piston starts on its downward stroke. It takes milliseconds for the explosion to develop (called flame propagation) Being pedantic it should not be an explosion , but a steady development of the flame front. It is not widely known just how slowl...

Re: Ported vacuum advance vs manifold vacuum advance

Well, my recollection is ( AFAIK ) prior to about 1960, most if not all vacuum advance systems were based on manifold vacuum. It was only with the advent of emission limits, particularly of Nitric Oxide , that ported vacuum started to be used , along with other bits of trickery such as ignition vacu...

Re: engine issue my specialist can't fix ... help!

If your local racing connection has a rolling road and/or an analyser like the old Suntester or similar machine, then they are probably your best bet . You really need to get the ignition analysed as a start and an oscilloscope based tester is probably the best for that , and even if they do not hav...

Re: engine issue my specialist can't fix ... help!

It may be harsh to say it, but your specialist doesn't sound as though they know what they are doing . Was there a loss of compression ? How much "water" was coming out of the breather so as to justify removal of the cylinder head ? If there was that much, then one would almost certainly have been a...

Re: Heat Shrink

It all rather depends on how thick the loom that you wish to re-wrap is, and more particularly how big the connectors are at the ends of it, because the heat shrink must be of a size that will pass over the connectors. You are almost certainly better off buying the proper loom tape ( not insulating ...
