This is the link to the article on head gaskets and the narrow slots https://members.tripod.com/~mopar_roadster/overheating_cure.html I have been modifying head gaskets for years and as long as you are careful there is no problem even after 100,000 miles. I open them up to the size of the holes in ...

Thank you very much for all your answers. I have given all your advice to the mechanic and I am sure this will help him.

There is an article in the Jensen Monday Club tech section. The gaskets with the small slots were designed to keep the heads hotter to improve (reduce) emissions. I opened my gaskets up to get more flow, it cured my “afterboil” issues when the car was shut off. You can see a bit of information in m...

Thank you for very much for your answers. I will have a look at the article from jensen monday club. Overheating occurs in normal driving conditions after 40 km. I have to stop due to Dashboard indication temperature. After that, I can heard that water is boiling. Il think the main reason of that pr...

Hi guys, I have some overheating problems on my rebuilt engine on Sincar 2606. We have checked the radiator the fans, the water pump,.. and everything is ok.

It is a complete restored car and engine. We use a new Aluminium radiator with modern fans (from Martin Robey) and new hoses.

I may be wrong but I don't think that's an original Chrysler 383 water pump. According to my copy of the Dodge workshop manual a 383" engine, with a 4 barrel carb, standard water pump (not air-conditioning) had 8 blades and an impeller diameter of 4.38" (111.25mm). This is the same for st...

I would go for the Flowkooler pump - have very good experience with them in all my V8 Jensen. But..... overheating is often caused by anything but the water pump......... Thank you for your answer. Yes we are checking all the different things that can cause the overheating but the difference betwee...

What do you mean by overheating? Is it just running hot which is almost normal or is it really overheating and boiling the water out? There is nothing wrong with that water pump by the way. :) It’s more the second solution. It is really overheating but i stopped before boiling the water. I agree th...

Hi, Due to overheating problems i have checked the original water pump of my jensen and i saw that is very différent from the new ones available at Martin Robey. The diametor of the lmpeller is bigger in the original shape. I think that was the case for non ac version (as mine is). Do you know wher...

Yes ! We are allowed to go out but not too far. We must stay inside a diametor of 100km. That is a huge step forward

Hi,
After two and half years, we can have our first drive with 117/2606. There are many things to end (wheel painting, boot ending, interior details,...) but were very happy to drive it. It wasn’t on the road since 1974 !
