Suspenseful Porsche 911 Carrera Engine Tear Down Findings - Part 2

Watch the tear down of my Porsche 911 Carrera engine as I investigate what's wrong with cylinder #5. I knew the engine was bad when I bought it, but I wasn't sure if it was a broken head stud, bent valve, bad valve guide, cracked head, or broken piston? Now I know after my longest video to date! Whew, thanks for watching!
