Way back in August 2013 I went to start my 914 and heard a funky noise. I immediately shut it down. Using my limited mechanical knowledge (and a tremendous amount of luck) I postulated that I had dropped a valve seat.
Three years later I decide it's time to get this 914 back on the road. Pulled the heads and, sure enough, a dropped valve seat. Prior to the issue the car was running good...no smoking, seemingly good oil pressure, etc. I'm hoping I can get by with just rebuilding the head (if possible). Anyone see anything that would cause me to deviate from this plan of action?   |

The engine was running good before this "incident". I'm hoping I can just change the head and get back on the road.. |
