Hi kh904 , i found something but not sure if this applies to my model , it says its behind the air intake pipe , so i will have a look if that's the case and will update
Many thanks
Just thought I'd post a quick update on this. What are we, 6 months later roughly? Racked up around 4000 miles since the repair. New plug is right where I left it, no leaks. Guess that's about as good as you could ask for.
