Engine coolant was gone. Filled up and went back home. Let the engine run and ther were a pool on the floor. Puh - no head gasket.
On the right side of the car, the Capistro header first lambda sond is in contact with the aluminium coolant tube. After 1000km the contact has made a hole in the tube and coolant is lost.
If you got the
Capristo header - take a look behind your right wheel.
This time I made a rubber tube fix of this, but I will talk to
Capristo Germany to have this issue solved. I want of course a new alloy tub. Rubber that close to the exhaust flange and catalyst is not a proper way to go.
Take a look at the photos and check your own car.
All the best.
