1987 930 Turbo 3.4L Twin Plug Ignition

This sweet '87 930 has come to us from Ohio for an engine rebuild & upgrade, along with suspension, A/C, and oil cooler updates. We started with a comprehensive disassembly & inspection, the engine was showing cyl. combustion leak at cyl. #5. 
We found that after careful inspection of the #5 cyl. head that it was incorrectly machined, and causing a deck height issue. This being #5 it was held off by the #4 & #6 heads and not sealing properly. Nothing that can't be fixed here, take a look!
