[Volvoline]

Thanks Keith ! It is obvious to me that the source is one of the pulleys. The powersteer works well and fliid is perfect with no leaks... Hmm..

So that whip is not normal you say - Is it safe to conclude the slippage comes from the AUX and there is no Cambelt danger ?

Phil it doesnt matter if the electrics are on, theres always belt slipping when i accelerate hard.
Also the whip is only near the tensioner. The alt is rock steady under revs, as well as the rest of the auxilary mechanism.
