Milky oil so I serviced engine & turns out head was cracked. Replaced the head & gasket along w it. Continuing to lose coolant, 300 miles later oil still looks clean. I’ve noticed when taking radiator cap off, no pressure is being released. Any ideas & suggestions??

Coolant system not pressurized -> higher temps -> evaporating coolant??

What I’ve done:
  • bled coolant system (looked good enough, maybe not?)
  • new thermostat
  • new radiator cap
  • pressure tested outside autozone, no leaks.
