Well after determining that my timing belt is too tight on my d16y8, i went through the process of adjusting the tension from what the manual says to do. After i tightened the adjusting bolt i thought i was all set but now it is way too loose and when i crank it the right side becomes loose and the right side becomes tight. When i crank it again the left side becomes loose and the right side becomes tight. I went through the process again and it still does that. When i push on the right side i can see the spring moving. Can some one please help on what to do? Also is there any way to fix this with out removing the bottom cover, i already have the top cover off.
The "right side"



The left side

 

Turn the crank Counter Clockwise until it is at TDC.
Lossen the tensioner bolt 180*.
Turn the crank Counter Clockwise 3 teeth.
Torque tensioner bolt.

 

tried that 5 times it doesn't work

 

Then get a new tensioner. Make sure the tensioner spring didn't fall off. How old is that belt? You may want to replace that too while you're at it, maybe a water pump too.

 

i just put a new timing belt in and water pump and the spring is on, i can see it moving, i got to where it is tight again but i dont think it is perfect, because i still hear some noises coming from the left side of the engine that dont sound normal

 

The only possible causes of this problem are:
1. something is wrong with the tensioner
2. you have the wrong timing belt
3. you're not tensioning it properly
