Cam Sensor Leaks

This bulletin applies to 2017-2018 Toyota Highlander and Sienna, 2018 Camry and 2016-1028 Tacoma models. Some vehicles equipped with a 2GR-FKS 3.5L engine may exhibit an engine oil leak from the cam sensor bolt holes. The flange bolts and the camshaft housings have been changed to address the issue.

If oil is leaking from one or more cam sensor bolt holes, remove the affected cam housing and install a new cam housing. Replace all cam sensor bolts on the new cam housing with the new upgraded bolts. Confirm that the leak issue has been repaired.
