I finally got my head gasket kit in so i could replace valve seals and get my truck to pass emissions when i was taking off my valve cover i noticed a scratch on the camshaft housing, where the camshaft comes out to the pulley. I was hoping for some input on whether or not i should worry about it, any idea how i could replace it or if i should just call it good and go dohc here's some pictures of the spot after i cleaned, it doesnt feel too deep but you can definitely still feel the ridges.SI851948.jpg SI851950.jpgSI851949.jpg
