This engine torque damper/shock fits great on a 1999 Toyota Camry with a 1MZ-FE 3.0L V6 engine. The equivalent Toyota OEM part has the part number 12307-20021 , which can cost two to three times as much as the MTC brand made. Unless there's an obvious oil leak, you cannot tell if this damper has gone bad without first having to remove it and compression testing by hand for rebound. I recommend this damper for those overhauling their entire set of worn motor and transmission mounts.
The old one, genuine toyota, was in better shape than "this new one", I left the new one in, but got my doubts. I might put back the old one. The old one seems to have a more constant resistance.
