Is this on start up? Does it go away when warmed up or is it a lot less? Often water will condense in the exhaust system after it cools down and will burn/boil/evaporate when you start up.. it looks worse at the beginning so that’s what is suspect. Your oil looks clean so no leak there, coolant would be constantly going down despite adding more and also you would probably have excessive pressure in the cooling system due to the engine compression leaking into the cooling system. The anti - freeze would probably be overflowing (if full) in time with the engine running. Since your coolant looks ok then a compression test would start to give you answers as it would be a lot lower in 1 or more of the cylinders. Hope this helps….good luck!

This is after a 10 mile drive and startup. It does this only when it starts

I’ve blown a head gasket in my old truck. It looks very very similar to this. Did the temperature every run high or was the radiator recently replaced?
