Volkswagen Polo no.1 spark plug keeps burning out

Car: Volkswagen Polo
Variant: 1.0
Model Year: 2000
Categories: Engine & Drivetrain
The no.1 spark plug keeps burning out and even after the mechanic trying several thing to fix it, it keeps on burning out. This has been going on for 9 months now and I have had to change the No.1 spark plug 4 times now! Can you suggest a solution?
Many thanks

head gasget likly check compressions
check for oil/water/combustion mixing
look in plug holes, is the bad cylinder cleaner on top of the piston this is a sign of it being washed by coolant,or if very dirty is a sign of oil contamination
