Got the front upper, back upper, and back lower bolts removed but struggled and couldn't get the front lower bolt. Did everything I could imagine, just couldn't get to to easily without having to remove the tensioner. I need to replace the O-ring between pump and cylinder head.
Advice anyone?
Anything is greatly appreciated.
