Hi, I went to replace my stock cam tensioner and found out my Tensioner guide and upper B guide were chewed up and making all the noise. I don't have a shop manual but I was thinking of takng the front cam sprocket off to get some room to remove the tensioner guide. If anybody can help me with this I would greatly appricate it. I can't seem to locate the mounting bolt for the tensioner guide. Please look at the pic carefully to better understand my situation. You can see the black chewed up guide on the front cam and the top b guide to the left. Thanks.
