This sweet 1987 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 cylinder. combustion leak at cylinder #5.
We found that after careful inspection of the #5 cylinder head that it was incorrectly machined, and causing a deck height issue. This being cylinder #5 it was held off by the #4 & #6 heads and not sealing properly. This can be fixed here in our machine shop, take a look!
