Technical Diesel Timming belt problem

[[email protected]]

Hi friend,
recently I changed the timming belt of my 1.7 Diesel engine from one of the local workshop, since then i noticed the noice of the engine has become slightly increased (tractor like sound), Before it was quiet,

any suggestions to rectify this, is this because the tensioner has be over tightend?

thanks in advance

Did you use the correct cam locking tools and procedure or wing it by using tippex, a hope and a prayer?

I am sorry I didnt get what you really meant by cam locking tool and its purpose,
I am not sure about it, because I was away when the workshop men did the work, but I am afraid that Camshaft need not be removed to change the belt,
