hey guys i did timing belt,all the accessory belts, tensioners, and a water pump change a feww months ago. When I put the CAS on the camshaft i screwed the bolts down too tight and it grinded on the front of the cam shaft and the back of the CAS. It grinded pretty bad and now I bought a new CAS and installed the and didnt tighten it too tight but I still here a grinding noise from somewhere. I cant find out where its grinding from. Any one have ideas of what I got myself into? Should I take the valve cover off and check for somethings before I have it towed to a shop? sorry for making it so long just wanted you to have an idea of whats going on. thanks alot.
