hey i have an h22a , mild head work was done to it about 3000kms ago such as valve seals , valves were replaced , skunk 2 pro 1 cams were instaled with skunk 2pro 1 cam gears , brand new timeing belt , water pump and water pump belt . when i leave my car over night to sit and go to get it in the morning i always check the oil and timing belt , well the past 2 days the timing belt has been a bit loser when i check it ( not so lose that it would fall off ) and after running the car the belt is back to normal ?? should i be worried about this or is this normal ?
