What happened to Packard engines from Pacific PT boats

Were Packard engines removed from beached PT boats, or might some still remain in the Pacific?

Most accessible engines were probably removed, but remote wrecks buried in sand could conceivably retain machinery.

Most Packard V-12 engines were removed before surplus PT boats were burned, but the panel leaves open the possibility that a few were missed. Remote Pacific beaches received uneven salvage attention after the war. Exposure and corrosion would destroy many remains, while machinery buried high in sand might survive in unexpectedly recognizable condition. Any recovered engine would still be a formidable machining and restoration challenge rather than a ready-to-run powerplant.
