In case anyone else runs into this, heres what to do... the stud that the tensioner pivots on IS bolted into the block through the Timing Chain Houseing. Behind the tensioner shoe,at the pivot point, theres a 10mm hex head. First you need to stick a punch tool into the hole on the shoe next to the stud. This hole is actually a clip that is spring loaded, when pressed this realeases the "lock" on the tensioner shoe (instead of a C clip). Pull the shoe simultaniously to remove, then unscrew the 10mm bolt/stud and remove the Timing Chain Housing, Vuallla! Thats something they dont tell you in the Hays manual, Bas*@rds!
