ok, first of all, you should know that the timing belt or chain in a honda is a critical part. if it is malfunctioning, DO NOT START OR ATTEMPT TO START THE ENGINE, You're asking, no.... begging: for valve damage if you do. Have it towed, have the chain replaced, period. End of story. You're gonna hear the same from others. -john in Iowa
