every now and then after driving slow or idling for awhile when i turn and accelerate i can smell oil burning and sometimes see a slight cloud behind my car. this happened before when i had a shitty valve cover breather. i changed it and it went away. i just recently bought a different one and it started again today? any clue to what this could be? theres no sign of oil hitting headers and burning and motor and blower are spotless? could it really be just the breather or possibly the bypass valve on the blower any help guys
