low rev mettalic rattle from timing chain area
picked up my S last weekend and loved every minute of driving her.
one slight problem. it has developed a slight metallic rattle under the bonnet when i put it in gear and rev gently to around 1500rpm the rattle appears for around 2 seconds then goes. sounds like its coming from the timing chain.
before anyone says it I have been to bmw and brought a new uprated timing chain tensioner and replaced that. loosing the will to live as i want to do stuff to my S but holding off untill i get the rattle sorted just incase its gunna be an expensive job.
all help would be appreciated.
