Exhaust gasket leak

It seems I can't get the exhaust manifold to seal against the head no matter what I do. I have even bought new primaries. It still leaked.




Now I have removed the gasket completely and tried to seal it with this stuff. No leaks, but lets see how long it lasts.

Min Stora Dag charity event

Min Stora Dag, or in english something like "My Special Day", is a non-profit charity organisation that tries to fulfil wishes from very sick children. The last three years they have organised an event on Mantorp where sportscar owners drives them around a racetrack. This sunny autumn day it was more than 100 very nice and fast cars that have come to the race track, and about 100 sick children with their families.

My car was very popular and I drove lots of children and their parents. Some older children asked me to "Go as fast as you can!" and it was always fun to see them shaking when getting out of the car, and then see if I could make their parents even more terrified than their children :-) Just to be clear - I never pushed any limits this day. An accident on a day like this would be disastrous.

One of the strongest impressions were this blond little girl Sigrid. I asked her if she wanted to go slowly or fast around the track and she responded "I know these are very fast cars. So please start off slowly and maybe you can go faster after a while." We agreed that she'd use the thumbs-up sign if she wanted to go faster, and thumbs-down if she wanted me to slow down.

When we got out on the fast straight she raised her hands above her head, just to feel the wind, and I could see she laughed loudly inside her helmet.

Back in the pit she laughed and said it was fantastic, and the big smile on her face was enough of reward for me for the the whole day. My body shivered for several minutes just for seeing how happy she was and how much she enjoyed it.

A great day and very rewarding, for everyone I think!

A day like this it would have been so much fun just to go around with my camera taking pictures, but I was so busy driving I didn't take a single shot. These are from various sources and I hope no-one mind that I'm using them here.

Yearly MOT - No problems, no worries!



Did two changes to the engine before the test:

  • Put a hose from the catch tank into the airbox (closed oil ventilation system)
  • Changed target lambda to 1.00 on low load and enabled closed loop lambda control.


At about 2500 rpm

Progress


Sometimes it is fun to look back and see how much progress has been made over the years. I'll never forget  my first track day with my Caterham. I'd traded in my Porsche 996 C2 for a Caterham and was terrified and a bit regretful because the Caterham experience was so much more in every way and I was not sure I was ready for it. I'm the first to admit I was not very good at driving back then.
