It’s right below my GPR on the back of the pass side valve cover, I’m guessing international didn’t do this

Anyone else have this on their truck?

Thanks- CL

Blind guy trying to make exhaust manifolds? Could be an arc from a ground or some sort of disconnected wire someone was testing?
Ah I didn't think about arcing, PO dropping the glow plug 'hot' wire on there and arcing it seems like the most likely cause

Thanks!
