My 2017 chevy malibu has positive pressure followed by wispy smoke.
Context: recently my engine overheated mid driving home because my serpentine belt came off due to water pump pulley breaking. i replaced the water pump n belt n now theres a blowby i think thats what that is called coming from the oil fill cap. Ive done compression tests on all cylinders n they seemed in line and good. i changed out the three outside pcv valves and hoses and i am still getting this issue. i could be wrong but there is another pcv valves inside the cover could that one be causing it?
