OK guys Ive got a large issue going on. I finished up installing a gen 3 on my 14 manual and was in the process of data logging a 3 gear WOT pull from the vendor supplied initial tune. It started to break up a bit around 6k and all of a sudden it sounded like a something let loose (sounded like a separated exhaust boom), immediate blue smoke out the back. CEL flashed for a bit then went off. I drove it another 3 or 4 miles home and pulled the codes, P307 and P308. No visible issues going on so I checked compression and looks as though cyl 7 is dead. I did a bore scope look and no signs of any damage to the top of the piston, but the top of the piston was discolored with an apparent oil film. The plug also looked fouled, no holes in the block, no contaminated coolant and no oil underneath. It starts and runs but I am afraid of the worse as something is majorly wrong.
So at this point my head is spinning trying to plan next steps in determining next steps here. I should note that prior to this it was running fine and AF appeared as good monitoring from the stock cluster gage pack.
If I fried the piston or rings can I replace the single piston, can it be done in the car if dropping the K member, I'm just sick at this point. Any further diagnostics suggestions ?
Sorry for the long rant, but any feedback is appreciated.
