Welcome to 2CarPros!
Given the mileage on the vehicle, I think it is safe to say that you are not burning oil. Not saying that it could not be but it is highly unlikely.
I was just looking at a picture of the engine on the side you indicated and one thing I was thinking is that the dipstick tube might be leaking at the base where it connects to the engine block. I have seen this a few times in my day. When the engine warms up the aluminum block expands at a greater rate that the steel dipstick tube and it could get loose and leak oil. That may explain the rattle too.
With the engine all warmed up, give the dipstick tube a wiggle and see if it is loose.
See the picture below.
