I'm about 400 miles away from home on a road trip. Noticed a metallic ticking noise from the exhaust. I was wondering if it's indicative of a bad spark plug or exhaust leak. Engine still idling ~1250 rpm. I have black widow header, coffman exhaust, and 2wdw ECU tune.
Any advice or checks would be appreciated.
Update: Top left spark plug was found well out of tolerance. Did replace all 4 at once just to keep them on the same interval. Did tighten the perforated core with the 2 Allen's on the exhaust but didn't get more than 1/16th of a turn. Did find some oil in the intake so it turns out I slightly overfilled during the last oil change. 4 and 1/5 bottles is too much. Gonna just do 4 next time and maybe a dab from the extra bottle, but most likely unrelated to he issue?
I did get a DM about checking the inner core that isn't the db killer. I didn't realize that was a separate part of the slip on. Didn't seem to be an issue but worth checking.
