Not sure video would detect rod noise on initial cold start. Have been told that advanced timing (about 36 deg) and 91-93 octane produces "Ping" and along with decked heads and block may be running 11 to 1 compression. Had a mechanic tell me the motor will self destruct with cold starts and dry bearings as a result of loose clearance / worn bearings after 1500 miles??
Suggests: dished pistons to reduce compression, new bearings,rings, and polish crank. Hopefully has not been hurt. Is already .010 under.
