Great to see the progress. Thanks for your efforts, Huib

Not to hijack the thread, but people have been suggesting other rubber products you might want to consider.
Earlier on I suggested the top hose ("hump hose" it is often called here) might be a suitable product. You and others have pointed out that there are silicone hoses out there that will do the job better than the original, and are an easier fit. I've installed these, but still found that especially the one inch bypass hose is a bit problematical, because the hose puts pressure on the bypass tube which is screwed to the thermostat with two cheesehead screws, and torsional pressure makes it easy to cause leaks at this point.
I have some thoughts I want to suggest, about these hoses in general.
Today's hoses, even the most flexible silicone hoses, are made out of multiple walls with inner membranes. This is because today's vehicles operate pressurized systems, whereas ours is non-pressurized. Because of this, they have to withstand much higher pressures in modern cars, and even the most flexible sacrifice flexibility for burst strength, to cope with the pressures. They also need to avoid kinking so they are designed with walls to resist folding inwards. Because every hose on the TD with the exception of the bypass hose (about eight inches long) is really just a coupler, joining two metal tubes whose ends are so close that NO hose would ever fold inwards, this feature is unnecessary on our cars.

Today's hoses are not designed for our cars; they merely make them so that these modern hoses will fit our cars, which is a very different thing.

I believe one could design a set of single wall silicone hoses that would work perfectly with our cars, fit better, install more easily, and have no trouble handling our pressures and temperatures. Such hoses would be MUCH more flexible than those currently on the market. They would replace the inflexible hoses we currently have with much softer, more flexible hoses that could slip easily on and clamp easily as well.

I'd love to see a set of soft single wall hoses made SPECIFICALLY for our cars and tested in the real world. I am sure they would work perfectly, and be much easier to install and adjust.
Just my two cents :)

The first samples of the side cover rubber seals arrived at my mates today also the first samples of MGA/MGB rubber rocker cover seals. They are now in the post to me. I will do some test fitting over the weekend.

Here's a photo of what they look like. The little lip is towards the front of the car as the seal is not symmetrical around the longitudinal axis.

I have finished the tooling for the link pin seals. We will do a few test samples during the week.

Declan,

May I congratulate you on your new MG rubber product endeavours.
From experience,I know that it takes a fair deal of research,development and tenacity to get a more than satisfactory,improved result.

One of the salient points MG owners need to take on board,is that gaskets of any kind will seal more efficiently when the surfaces on which the gaskets are to be applied,are in fact true and flatI (in the case of Rocker Cover and Side Engine Plate Covers).

I wrote an article on the above theme some time ago which is liisted
on the MGTC Owners Club(WA) website for those persons interested.

Well done on the effort.

Cheers.Rob Grantham

Declan: Looking forward to them. These two rubber parts are the worst part about my car. With today's rubber you don't even get a year out of them.

While swapping them out is not terrible (except the bottom boot), it should be a 10 year event, not yearly. I look forward to not replacing these once your are installed. :-)

Here's the first TD/TF/MGA kingpin link seals moulded today-still some fine tuning required but getting there.

Looks great Declan!

Very artistically photographed Declan.

Looking forward to hearing when you are satisfied with a finished product.

I have had the good fortune to be trialing some of Declans products under Australian climate conditions.

For those that arent aware we are currently in the height of our summer season. Trunnion dust boots have been exposed to temperatures in excess of 40 degrees C, rainfall intensities of 200mm in 7 days, humidity over 90%RH and coated in moly grease, absolutely no degradation of the product has occurred since early last December.

Today I fitted one of Declans tappet cover gaskets to my TF. Precision of fit and rubber Dur meter hardness are perfect for the application.

The amount of dedication this gentleman applies to providing us T type owners with high quality products deserves 5 stars.

Thanks Declan.

Thanks for the nice comments. The photo was taken by Hans Dieter Gollus, who does the moulding, and will be looking after the sales of the rubber parts. He may be contacted at info@engolit.de

Fine tuning is finished. The first batch of fulcrum production seals was done this afternoon so complete sets consisting of 8x fulcrum pin and 4x kingpin seals are available for dispatch as of Monday.
Seals 3 Euro each and international worldwide postage for the set is 3.70 Euro.
