Help HELP HELP Whats wrong with my car

[Subiwagon]

i have a 2003 wrx with AP stage 2 downpipe uppipe bola 3inch cobb intake. i was driving the car home from a shoot out an i went to the gas station shut it off and it blew a ton of white smoke. check the codes said it was missfireing. i replaced the plugs codes went away. then it went away. then im driving home the car overheats. i take it to my garge pressure test for head gasket it passes the pressure test. i let the car idle for about 20 mins dose not over heat i take the car around the block build boost then it over heats. i shut off the car then start it still warm blows white smoke when its cold it dose not blow white smoke. i think its the head gasket but im looking at the heads and there is not even dirt on them they look brand new. im totally lost i need help ASAP.

Heads 80% of the time don't leak externally. I would do a coolant analysis test.

coolent test came out perfect. car runs perfect until you drive then it over heats does not overheat when its first started then after it is warm and you drive it over heats once the car is warm and you restart it it will overheat at idle thats why im thinking head gasket cause wants it get hot enough for everything to exspand it overheats. it just does not make sense besides they when half ass on the head job.

there is a minor oil leak on the right side of the motor which makes me think to.

white smoke makes me think head gasket. but goodluck. see if u can notice any leaks when its hot

[Subiwagon]

when it was idleing that when it was having the small leak from the right head
