I joined the forum to find someone who could give me a second opinion. My 2000 Subaru Outback (136000 miles) recently developed a tapping noise - mechanic says it's piston slap and has recommended I replace the motor with a used one- for $1700. I've been researching this noise and think it might actually be a bad timing belt tensioner. So - two questions - how bad is piston slap? Can anyone redomm me a good place for a second opinion?
