Was at 260º for all of about 1 minute. It was probably the 24psi boost over the course of 25k miles. I've got about 33k on this motor. So going back to 17k is kind of refreshing. Hahaha.
Now I'll have 2 non-op 1.4's in my garage. Maybe once I'm free of my loan I'll finally build one up. I'll definitely look into head gasket/bolt options if I do.
