My Everyday MG

I’ve owned my 1974 MGB Roadster for 34 years. In the late 1970s I was a part-time volunteer Sunday morning Supervising Instructor for the ACU/RAC Motor Cycle Training Scheme. This was the Watford, Hertfordshire, branch and part of training was to take pupil L-plate riders onto the road under following Instructor supervision. An earlier ‘convoy’ run had (theoretically) shown the pupils the route and sequence of roads to be traversed.

On a few consecutive Sunday mornings I noticed (while still observing a pupil!) a nice looking Triumph Spitfire, and decided that I should have one, but my Triumph motor cycle wasn’t going to go in part-exchange! I saw a nice one for sale in St. Albans, but by the time I returned with my wife it was gone, and had been sold.

Still checking the car sales pages in our local newspaper I saw this 1974 MGB Roadster advertised at £1,500.  That will do,” I thought, and obviously after 34 years of ownership it was the much wiser choice.

There was nothing wrong with the car, but simply the vendor had been given a company car and his wife was too short in the leg to be able to drive the B. Stopped, while talking, during the test run, the engine was left running and it started to falter and run rough. The vendor talked his way around that, and I have to say that it has never done it since.

Most days the MGB took me the 16 miles to work, and later 20 miles when I moved from IBM Education to Marketing Staff, further into London. (Other days I used my motor cycle.) Having a garage full of vintage motor cycles, the B has always been parked outside and I drove it throughout the year, whatever the weather. It was protected simply by a car cap, which covered the top of the car to the bottom of the windows, so when frosty and snowy I simply rolled the cap off and the windows didn’t need scraping. (I had purchased a hard-top in need of attention for £15 shortly after buying the car. It now lives under a full cover as protection from the sun.)

In the 148,000 miles in my ownership I think it has only let me down twice. On a hot day it once overheated in traffic and wouldn’t restart until the engine had cooled. Conversely on an icy day the carbon thrust bearing of the clutch broke up.

Another failure, although I still managed to get home, was when my local petrol station reduced the tetraethyllead content in petrol to one sixth its previous amount, and when ‘bombing’ down the M1 the engine lost power. Fortunately I was close to the turn-off to home and by keeping the throttle open was able to complete the final six miles. I knew that if I allowed the engine to stall it would not restart again. Just 60 miles off the ‘magic’ 100,000 miles, that turned out to be a burnt valve seat so I removed the head and had it reconditioned with hardened valve seats. A little later, at 115,700 miles, I decided to have the bottom end overhauled as well, although I don’t recall that it was doing anything naughty.

After a number of years the bodywork was showing its age so I had a respray done, but that was a waste of money as it turned out to be a ‘cowboy’ job. You sometimes gets what you pays for!

Later, with rust showing on the sills, I knew that if it showed on the outer panel the unseen inners were probably worse, and as on a Roadster the car’s strength is in the sills I decided to have the whole lot inspected and replaced as necessary. Although done in a large ‘back garden’ shed it was a very professional job and I think I ordered all body panels for replacement, apart from the boot and the bonnet. I had replaced the bonnet much earlier due to rust in a forward corner.

So there has never been a month that I’ve not used the car (apart from the months | was overseas teaching computer engineers in America, New Zealand and Switzerland), When I moved to a position in IBM’s Marketing Staff they wanted to give me a company car, but the last thing I wanted was another car (garage full of motor cycles, two cars in our driveway, and an MG YB in a rented garage four miles away), so IBM gave me £100 a month instead to cover insurance, road tax, etc. and the MGB became my ‘company car’.

With heavy traffic to the outskirts of London, and later further in, I tended to get around 26 to 28mog. After the engine rebuild I ‘ran it in’ more gently on a business run to Doncaster on the motorways and obtained well over 40mpg on that occassion. Now in New Zealand where the weather is much kinder and the official speed limit 60mph, I regularly obtain 32mpg on 20 mile runs.

My records show that over 34 years and 148,000 miles I have replaced the prop shaft universal joints, clutch master cylinder seals and hydraulic brake-light switch, each three times, clutch cylinder seals and the HT coil, each twice, and got through’ twelve tyres, although it’s hot really fair to count two of those tyres for inadvertently caught the sharp kerb edge of the driveway and heard ‘bang, bang’ as both the near-side tyres split.

The alternator has been replaced or repaired twice, and when the car was 8 1/2 years old I fitted a pattern petrol tank.

I had an abortive attempt to use silicon brake liquid, but it messed up the brake servo, which I then had to replace, although my manager at that time managed to successfully clean it out and use it on an MGB that he was restoring. (I successfully use silicon brake fluid in my MG YB.)

Over the years there have been less significant replacements such as rear springs and front wheel bearings, plus natural replacements such as brake pads or shoes, although brake pads and shoes fast me a long time as I make use of the excellent gear spacing and engine braking rather than the brakes, which only come on for the final stop. I see that it’s 68,000 miles since I replaced the front brake pads and there is still almost half the pad thickness left.

Prior to running he engine I now use a 400watt water pre-heater in order to reduce engine wear, ensure a rapid engine warm-up and have the heater (with ‘Costello fan) operational immediately. It was something I could certainly have done with during Britain’s winters but I’d not seen them over there since the 1950s.

Complaints? Well, it is getting more difficult to get into, but it’s a ‘knack’ rather than a serious ‘no, no’. However, the steering is and always has been heavy, which is really surprising for such a light small car.

I’ve no immediate plans to sell the MGB. It’s still my ‘everyday’ car!
