changed intake gasket but still the same.when it first flashes theres a cloud of white smoke. when i rev it up same thing. head gasket? would that cause me to sputter and loose power if there was coolent getting in the cylinder? havent noticed a loss of coolent. I have dual exhaust so i can see that it is only comming out of passenger side or the even bank. cylinders 4 &6 are low on compression. help
