0 to 628mph / 1010kmh in 50 seconds

Some Further Wolseley Hornet Autumn Photos.


Exhaust System (Tailpipes not yet trimmed to length), manifold to have further attention before painting.


Passenger side heat shield.




Perhaps the competitors view?


Heat shield mounting boss being bronze welded into position. The second "lozenge" shape mounting, ready to bronze weld on to the back of the Brooklands Can, can be seen in the background.
We will also weld a threaded Lambda sensor mounting bush discretely into position behind the heat shield, to allow an occasional monitor of the mixture.

Making exhaust mountings ready to bronze weld to the back of each Brooklands Can where a bolt and post will travel through the body skin to pick up with a bulkhead mounted bracket; avoiding any loads through the aluminium body of the car.

Autumn At HEC

It has been a busy and eclectic autumn period here at the HEC.
Here are a few photos to illustrate some of the work:

Wolseley Hornet: 2 litre capacity breather container fabrication to comply with RAC competition regulations








Wolseley Hornet Exhaust: passenger side "Brooklands Can" heat shield, as light and efficient as possible:







Wolseley HT Lead conduit:
(please ignore temporary modern fuel hose to pump)



Porsche 944s. Attention to a few paint details before continued re-commission and engine peripheral work:





Triumph Dolomite. The beginning of a great Journey, we will enjoy this!:









Morris 8, Carburettor service as this little car will be in regular use throughout the winter.
We built the engine about eight years ago, it is always nice to see it out and about along the Dorset coast on a regular jaunt. Sometimes old is better, what better way to travel along the Dorset coastal lanes and cliff top picnic.. even in winter!



Morris Minor
(Pre War)

Replacement of very worn hubs:

1930's Peugeot 401 Engine Machine Work







1. Showing the bearing now roughed and fitted into the crankcase.

2. The flywheel has been balanced. 

3. The rear main showing the housing and oil return collar that will mount on to the crank and run within the housing. This will become a rear datum for machining the main bearings. 

4. Indicating some of the areas where the crank has been balanced.

Wolseley From July / August

Some photo updates from last month's fabrication work, more to follow as I extract them from various phone cameras:







Porsche 944S




We have some recommission work to carry out on this very nice condition Porsche 944s.

Most of the work will concentrate on a little rust treatment and cosmetic recovery as well as attention to the oil pressure relief valve and some ancillary mechanical work.

Help Required, 1932-35 Hillman Minx Con- Rods!

We are trying to help a friend in the USA to find a set of con-rods for a 1932 Hillman Minx, we believe the same rods were used between '32 and '35.
Any help would be greatly appreciated.

I can be contacted on Eric.O'Hara@fiennes.co.uk




Thank you for your help..

E Type..SU..HD8 x 3 = Phew!



Well this was a little more in depth than I had expected.

Our brief was to look over the carburettors as well as a few other jobs on this lovely 3.8 Jaguar which was a little down on power.

I have always been fond of the E Type, especially having realised that the marque was released on my actual birthday in March 1961. Patience for this job was not an issue as the HD8 mechanism and E Type beauty never ceased to be enjoyable. However, the clock over my shoulder was relentless!


Although I have worked on various Jaguar carburettors of the period, I had underestimated the amount of time it takes to overhaul a set with the additional third item, especially when it came to throttle shaft renewal and bush work. It also became very clear that corrosion has been an issue, the aluminium body having considerable white powder where dry and a dark witness of previous corrosion in the material beneath the fuel dampened areas. Much of the brass work had green verdigris along with more white powder in and around the jets and fittings.

Reflecting on this condition with Will Fiennes later in the week, remarks were raised regarding modern fuels, ethanol and "other"content. In fact, what Jacob and I had found was remarkably similar to the findings in my Methanol Weslake motorcycle engine on the weeks that I had neglected a pre storage carburettor clean. ... Something to think about?
Even the steel air bleed volume screws had lost their substantial tip to corrosion requiring the machining of one to become a lapping mandrel to recover the seats in preparation for three new.. plated.. items.

After lots of fettling time and attention to one carburettor that has had the throttle shaft bush locations bored all of the way through, removing the thin section of throttle body wall that the bush is designed to meet. This will allow complete throttle housing bore concentricity and avoid any risk of vacuum escape around the butterfly in this region.

During a routine check of the fuel filter in the King Price regulator / filter, we discovered the complete regulator check valve collected inside of the filter. The unit has been retained by a light press fit and "staking" at four points... I think the stake tool must have been a little blunt when factory assembled!

Finally all back together and tested before returning to the owner, his e.mail was a welcome find later that evening.

To summarise; Triple SU HD.8 overhaul is no "quick job", but well worth it. And keep ethanol and classics in mind..



"Hi Eric and Jacob,
