Wanting to get your guys thoughts.
I re-timed one of my 4g63 engines and after sitting for a few months I went to place it in the car. After getting placed it in the vehicle I noticed that the timing belt was rather sloppy between the cam gears. Since I just placed the engine in I figured I would rip it back out and check the tensioner. What do you know, the tensioner inner hole for the grenade pin is lower then the outer.
After thinking to myself, I place everything in alignment. Going back to the tensioner I see I can now slide the grenade pin in. Note, when in time, i have more tension between the cam sprockets.
Im was kinda baffled so I ripped off the head to do a valve job, wanted to insure the valves were good. (It was a spare head and I wanted to redo timing anyways.) This has nothing to do with anything. I just got frustrated.
So would there be a reason why at some portions of the cycle you loose tension? Its a new oem tensioner and new pulleys etc.
Thoughts are welcome.
