A real treat this year is the British Classic Car Show. This will be held on Thursday 19 to Sunday August 22 at Farnborough International Expo Centre GU14 7JG. The MGB Register will have a stand at this huge event and wishes to have ten MGBs on show each day on the stand.
If you are interested in showing your car on the Register stand please contact John Watson, mob 07775 75236, email:firstname.lastname@example.org in the ﬁrst instance, and sooner rather than later. All details of this event are, predictably, on the Register web page at www.mgb-register.org/events.
I noticed some comments on one of the MGB Facebook discussion groups the other day about changing from a dynamo to an alternator. Obviously, this only applies to MkI cars and would also involve a change of the polarity of the car from positive earth to negative. I contemplated this myself a few years back and was strongly advised not to do it on two counts by two separate motor engineers. Point one was that an alternator pushes out far more power than a dynamo so the risks to the venerable wiring loom increase (possible insurance implications) and two, apparently, the change in polarity causes an increase in the rusting process. I have little reason to doubt the veracity of what I was told, and reduced the load on my wiring loom by ﬁtting LED lights and installed a replacement dynamo when the original gave up the ghost, but wondered if anyone else had any knowledge of this rust increase suggestion?
The picture of my engine shows the one visible alteration I have made. I have put the sump breather gulp valve in a plastic bag and stowed it away. Instead, there is a catch can mounted on the offside inner wing with a vent down into the airstream which successfully carries fumes away from the sump and eliminates the risk of the rubber diaphragm in the gulp valve rupturing.
