My 2017 BRZ STI blew a motor for this exact reason at 74,000 kms . I have pictures to prove excessive application of silicone which covered 50 % of port that fed oil to the crank. Purely the fault of Subaru as I babbied this car. This was an absolute nightmare and I had to swap my motor to a 2018 2.0.
