If you’re curious as to how Subaru engines are disassembled and assembled, the two videos below are bursting with knowledge and pertain to the EJ257 (STI engine in this case).
What’s cool is that the person in the video is a master Subaru technician. He explains a LOT of things (with the help of the person behind the camera). As well, he explains such terms as cracked ringlands (30 minutes into the assembly video). Ever heard the term “spun a bearing” and don’t know what the term means? He explains that term. He shows what bearings are and shows the differences between forged & cast pistons (and explains the differences between the two). He also shows the damaged caused by driving these cars with no oil.
These are great videos!
Note: I’m having a hard time finding the disassembly video, but will post it here when I find it.
