the lower heat shield, the one that goes over the turbo itself. and maybe it will have problems, but i am having more than i should for a simple timing belt change. the sick part is, most of the trouble i am having is with acc belts. first the auto tensioner failed, then we put the outer drive pulley on backwards and it was shredding alt belts, now it is making a slight faint noise that i dont know what it is. this latest problem is probly not that big a deal if anything at all. you know how your ears are more sensitive to sounds when you are working on your own car. ha ha. thanks for joining up jeff, wondered if you were gonna show up. :thumbsup i would take a vid clip, but you probly wouldnt be able to hear it, yep, it really is that soft. hmmm...
