The key points are that there are 4 operating stages, and that there is not enough fluid to couple the system adequately.

If the one-shot system is working properly, it is usual to see oil dripping down the insides of the front tyres when the car is parked. If you see a stream of oil on one side but not the other, it is possible that the system might be blocked on that side. It is also possible for the non-return valve to stick open, so that oil seeps out regardless of whether the pedal is pressed.

As described in the history section of this website, the Bristol Aeroplane Company made its first car in 1946. It was based on pre-existing BMW technology, rescued from Eisenach at the end of World War II. The Bristol 400 essentially combined the best features of the pre-war BMW models, coupling the chassis of the 326 with the race-bred engine of the 328.

A Vokes-type paper element oil filter was fitted originally; almost all engines by now will have had an adapter fitted so that a normal disposable screw-on oil filter can be used. In many cases, an oil cooler will have been fitted too, although Bristol Cars and other experts insist that this is not necessary except in the most extreme conditions.

The end goal of a cooling system is to transfer heat to the surrounding air. All the other components are only there to allow this transfer to occur in some improved fashion. There are plenty of air cooled motors in existence that do not have these complexities, and they too may be subject to overheating.

In theory, any of the Bristol six-cylinder engines could be installed in any of the cars. In practice, it is not too uncommon to find 400s, 401s and 402s fitted with later engines. The opposite situation is rarer but not unknown.

The following sections presuppose some familiarity with assessing cars in general, and are intended only to point out specific features of the Bristol. These sections are organised against the same headings as the Bristol 400-403 workshop manual, which is available in facsimile form from the club.

This is a double wishbone design with a single transverse leaf spring forming both the lower wishbones. The exposed ends of the leaf spring should be covered with leather gaiters, intended to keep grit and dirt away from the leaves. The gaiters deteriorate with age and it is not unusual to find that they have been removed. New gaiters are available.

All six-cylinder Bristols were based on the same BMW-derived combination of chassis and engine, with relatively minor changes until the last Bristol 406 was built in 1961. The What to look for section is therefore identical for all models, at least in the mechanical department.

It is worth checking to see that the starting handle is present (in the boot on the 400, clipped to the right hand side of the engine bay on other models) since it is useful for setting valve clearances and for fitting fan belts as well as starting the engine.

If all the basic checks have been performed on the cooling system – no leaks, nothing obviously blocked, quick warm up, infrequent overheating except under specific circumstances, then it is a fair bet that the overall system is simply marginal. In this case, a dramatic increase in specific areas may yield a significant benefit.

On the aluminium-bodied cars, corrosion will appear where steel meets aluminium, particularly where insulation between the two metals breaks down. On the 401-403, this tends to be on the sills and immediately above the front bumper. Although seldom terminal, this can be unsightly and is expensive to repair. All body panels for these cars have to be made from scratch.

Bri19874 months ago

The 406 was a larger car than its predecessors, and more of a luxury car than a sports saloon. Future Bristols up to the 411 would retain the same basic bodyshell design.

On all models except the 400, which has no fuel reserve, the fuel feed unit consists of two copper pipes of different lengths (for main and reserve feed) descending into the tank from above. Occasionally these pipes crack, resulting in a car which seems to run out of fuel even though the tank is still half full.

The interior is trimmed in high-quality leather; it is extremely difficult nowadays to obtain leather of the same thickness. A car should ideally have a high-quality retrim or an attractively patinated original interior. A vinyl or cloth interior, or an original leather one that is tatty to the point of falling apart, would typically cost over £6,000 to replace.

The maximum amount is when the reservoir in the front is full and overflows through the central hole. Not so simple though, as full is controlled by centrifugal force, so when operating it fills the “outside” of the reservoir, not the bottom.

401-403s have aluminium fuel tanks, which are held in place by steel straps. If moisture has been allowed to penetrate between the tank and the straps, corrosion will follow. Removing and repairing the tank is a time-consuming process.

There is a one-shot lubrication system which supplies oil to the king pins and steering rack. This is a reliable system, but it does appreciate being used regularly. It often gets disconnected and replaced with grease nipples, necessitating a lot of work to put the one-shot back into operation.

The 406 was the last six-cylinder Bristol. Cars generally had become very much faster through the 1950s; what had been a very rapid car by the standards of 1946 was now beginning to look expensive relative to the performance offered (somebody had commented that you could buy seven Jaguar litres for the price of two Bristol litres). From now on, all Bristols would have Chrysler V8 engines and automatic transmission. They were much, much quicker, but somehow they weren't quite the same...
