Speaking of headgasket issues, i just read up on the thread in the legacy forum. And i caught some symptoms that lead me to think all my CELs lately may be pointing towards a blown head gasket on 2-4 side. Im always gettin misfires over there, i have somehow lost 2 qts of oil. Whips of white smoke comming from under the hood after hard driving when i come to a stop. Any agrements of disagrements?
