FA20 & FB20 Engine Build Problems Subaru FA, FB 3rd-Gen (How to fix 2022)

The FA20 engine used in the Toyota 86, the Subaru BRZ and its variants have a flaw in the valve rocker design that causes it to fail. We have been involved in a Toyota 86 Race Series for the past year and a half, and during that time we have had to replace 3 blown engines on a single car due to this issue that was unknown at the time. Toyota explained that it was caused by overrevving the engine, but as the issue continued to occur we were unsatisfied by the explanation given by Toyota, and so we at Denstoj Auto Centre have design a retainer system for the rockers to prevent this from ever happening again. 00:00 Demonstrating rocker falling out 00:21 Engine and gearbox out of vehicle 02:19 Pushing rocker with pry bar 02:46 Rocker retainer solution 03:19 Replacing pivots with modified ones 04:00 Installing rocker retainer clip 04:27 Re-installing rocker This affects all 3rd-Gen Subaru Engines (FA20, FA24, FB16, FB20, FB25) from 2010 to 2022 (current). #fa20engine
