Now Brian, in the past you have taken exception to me repeatedly quoting the Factory Shop Manual... now you want to discuss the lack of that instruction in the manual instead of arguing the physics and design logic ?

Keep in mind that there is not just 'one' Factory Shop Manual... those messed up numbers instead of page numbers and repeats of entire sections show they were just compiling and adding changes and updates...

I can find in mine what you note is missing in yours.... but since you did not accept in the past my references to the manual.... can you see from looking at the design of the gears, the function of the tensioner...and its location... and claim that tension is not needed to maintain the specific number of chain links between the important items on the driver's side of the engine...given the potential effects of gravity at a time that tension is not maintained ? No shop manual... just the logic or lack of it with regards to the design of the engine....yea or nay... ?
LOL
