Hi thanks for the new suggestions. Hi Colin/Andy, I'm pretty sure its not that the squeak is when the engine is off and directly comes from the cambelt. Stu, I have a manual tensioner, about 5mm flex of the cambelt between the cam pulleys. The noise comes from the belt itself, running round the cam pulleys/crank/pump etc. I think I am just going to replace the belt and tensioner...? Ian, I have previously found the correct method posted by Revilla, my engine is a DVA modified non-VVC, it does not have the threaded fixing point for the manual tensioner kit. Sadly I realised this after I have bought the kit.. :-o Photo... Thanks so much for the support, it is good to know I am not mad [i think] Julian
