Tomei Camshaft TCT Release Tool For Mitsubishi EVO 4B11
Tomei TCT Tool for changing camshafts on the Mitsubishi 4B11 Engin.
How to release the valve timing chain - Insert the precision driver (or similar tool of the same size) into the special service hole where the Timing chain tensioner is and hold it in there to keep it unlocked. The TCT release bar is then to be inserted into the timing chain gallery between the cam gears and pushed against the timing cam gear ASSY on the intake side which will push the chain tensioner inside the case and make it loose. Whilst the screw driver is in the service hole the TCT will relieve the tension on the chain when the TCT is pressured up against the tension.
