My 1999 WRX is well overdue for a timing belt replacement- Only done 75,000kms but 20 years old!
I am going to do it myself and am concerned about camshafts getting out of sync so am considering cutting the existing belt along its length , removing and then sliding the new belt into position over the various sprockets and rollers.
Once located , the remaining old belt can be cut away and the new slid over into its final position.
Has anybody tried this with success ?
