Only thing steel that I can think of is a bolt from the intercooler. And then I think it would be hard to get sucked up into a cylinder. Did anyone remove or replace the intercooler?
I removed the intercooler when I had the engine built but that was 3 years ago. If a bolt had gone threw I would imagine a lot of damage. The nicks and dents seem to be about .050 item that left damage. Very small. Did a 180 miles with it yesterday with multiple pulls. No issues except for the clutch starting to slip. Guess im going to forget about the engine stuff and go with a dyad clutch now. Stock clutch has been holding for 36000 pushing 700 rwqt and 780 rwhp.
