so i got a new water pump/therm, hpfp, remanded injectors, inlets, catless downpipes w custom 3.5 inch exhaust, pcv valve "upgraded", oil catch can, new coil/plugs, walnut blast, new oil filter housing gaskets and yet i still have smoke coming out the exhaust only sometime i haven't actually driven the car in months but last time i did it overheated and i had to get a tow but it was the coolant overheating and not the oil. so after problem shooting my ltfts being high and trying to do "maintenance" I never got it 100% and I've concluded that i have a blown head gasket via a combustion leak detector and i believe the cause of my ltft being +20s is the coolant in the cylinders but before i pull the motor what I cant under stand is sometime when i start it it doesn't smoke at all and other times it does I'm so confused on what to do the codes i currently have are

2E83 electric coolant pump power reduced operation.
2EFE electric fan, activation "have my fan out for easy of access"
2E9F oil condition sensor
