should i replace J tube?
 

I noticed a puddle of oil just under the Air / Oil separator and most probably the culprit is the J tube. I noticed that the O ring was thorn. Should I try to find some replacement O rings or should I just buy a new J tube?

You would likely have a vacuum leak and idle issues probably accompanied by a CEL if this was the culprit. I mean, it's cheap enough you can do it easily. But I'd think if it was an issue you'd have other symptoms.

I just ordered the j tube, wasn't expensive anyway. I'll see how it goes after I replace it

probably the oil fill tube that runs from the trunk to the engine - it has a joiner right at the aos that will drip oil if you are chucking the car around.

I will check about that. I didn't know that "chucking the car around" could cause oil leaks. I still ordered a new j tube,as I said, wasn't expensive so worth replacing anyway.
