from what has happened to some on this site and from what I have read about getting the cams back in time if the belt breaks.
1st make sure the marks are lined up before removing the belt.
2nd don not turn the cams without the belt being on. if you were to turn the cam 1 turn and put the belt on the cam timing would be off.There is a TSB about retiming the cams take a look at it and it will answer the question as to what would happen. shawn
