After I had my timing chain at a service my cylinder 2 spark plug was burned. I changed all spark plugs and just 150km later/ 2 weeks same spark plug was burned. Changing the spark coils didn't fix the issue. From what I've read fuel injectors might be at fault, but they are harder and more expensive to replace. Before doing anything else I would like to know on how to make sure it is the injector and is it possible just to clean and replace the o-ring on the current ones.
Here is an image of the spark plug after 150km.
