will have to try super unleaded uk 98 RON...about $2 us a gallon but if that what it takes,

will check the pullies etc , the weather here is turning now and little day light but will update when i can, the knocking is only noticeable on the right top part of the engine when you look at it ...but all suggestions worth a try
