No only thing that’s been done is head studs, it’s not loosing coolant I think it’s just left over from when I used archoil in the previous oil change, I’m waiting on oil to come in so I can change it again and see if the potassium goes down. I’ve made it to 12k miles on this oci and with it being my first use of amsoil I think my next run I can get an easy 15k. Also thanks for fixing it lol
