Thick white smoke started to come out the exhaust, im thinking its either blown seals or the head gasket
but i checked my power fc commander and its showing the F/P and the o2H dot filled in, the BKS dot would be filled in then be blank again

i know the F/P is the fuel pump control and the o2H is the o2 sensor heater but what is the BKS?

when discovering the problem i was driving, and the bov sounded to get weaker and weaker also, idk if that is helpful info?

with those codes, would it be blown seals or a bad head gasket?
i checked my charge pipes and no oil =\

thanks in advance!
