I just started looking into my other motor to get an idea on what kind of shape it was in to see what surprises in might be hidding for me when I rebuild it . The first thing I discovered was when I removed the oil pan I found the broken off end of a scew driver and a spring. So I figurede I better dig a little deeper . I pulled of the timming chane cover and discovered that the tensioner was destroyed, the screwdriver !. Then when I tried to slide the cam out it wouldnt come out, so I unbolted the cam towers the all slid off easily except the center one it spins but will not slide off the cam. This is the reason for my post , shouldnt it slide rite off? If I have to replace it will I need to replace all five ? Where could I find new cam towers? any help would sure be appreciated.
