i've searched the forums and found a few possible answers to this question but wanted to repost to see if there was anything new. about 3 weeks ago i started noticing a burnt oil smell when i got on the motor pretty hard, it then would go away. I've got 47k on the motor and can't find any leaks and nothing smokes. I think it may be a pcv, but would a new one fix the problem? it seems to be coming from the middle of the car also. thanks for any help!
