I have noticed a lot of ' tinny ' high frequency sound coming from the top of the engine
at idle is this knock ? I show a lot of knock below 950 rpm when engine is rough but knock is gone by 1300rpm on safc2 when I rev the engine.
I have been ignoring this but could do with some ideas should mention I do use a bit of oil.
