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?   |

I did the same thing back in 2000. Had the head rebuilt, didn't touch anything else. Put it back together ran fine for years after. Sold the motor in another car when I did my conversion in '06. Never heard from new owner so I guess it was just fine for him too.
Depends on if the engine was running fine before? |
