I recently received a set New K24's that had failed. I did not sell the units, but was instructed to repair them.

Here are a few pictures of what wiped them out.





These check valves were originally installed on a '02 996TT. The owner purchased a new set of K24's. Instead of ordering new check valves, the old ones were installed. One can notice that the valves is/are a two piece design. A stainless steel screen is used to filter out debris from entering the turbochargers bearing system.

When one makes the decision to re-use the check valves, you risk disrupting the filter screen layers. The debris migrates into the turbochargers. Bearing failure is 100%

Why does someone spend $2,500 to $3K on a set of K24's and then mounts the old valves.
