On the way back from a bike ride, at dusk on the motorway, the engine started to cut out... Brrrr! I made it back, i'm used to drive old cars in various state of disrepair.
Wanting to avoid another costly repair, i checked the engine myself. The mechanics who had changed the head gasket had tightened the spark plug so much that i broke the first one i checked:
Back with a new spark plug, i looked for other problems and found that the botch repair i did on the air filter housing - to get me to the garage last time with the back firing problem - could be causing the fault: the gaffer tape wasn't holding the two pieces together anymore, instead it was flapping inside the duct, reducing airflow to the engine. This time i glued it - again to get "to the garage":
By then i was thinking that it was wise of me to have abandoned engineering for a more intellectual career. Not surprisingly, this was not the cause of the problem and the car is now at the garage. Hearing my tale, the mechanics suggested a faulty temperature sensor, something that is quite common after a blown head gasket...
The story doesn't quite end there. As i was emptying the car, i noticed liquid dripping under the engine bay: a gas leak! - my car runs on LPG- So i can count myself lucky that this was found before bringing the car to the garage, not after!
