Magnetization of Valve Tappets
Vehicle Type:
Boxster
Model Year:
As of 1997 (V)
Concern:
Magnetization of the hydraulic valve tappets (lifters) can result in failure.
Information:
Magnetized tools or magnets must NOT be used during removal and installation of the valve tappets. This applies to all valve tappets that are to be
reused
The magnetic properties of a magnetized tool or magnet, if used during engine repairs, can cause the valve tappets to fail. For example, the ball of the
check valve inside the valve tappet may become magnetized and stick.
When performing engine repairs, only use a suitable non-magnetic tool such as a rubber suction cup (e.g. valve lapping tool) to remove and install the
valve tappets.
Disregard all previous information referring to the use of magnetic tools on the valve tappets. Please update your Technical Manual with this
information.
