Thanks for the info. Glad to hear that is normal - all of the information I found online referred to the oil separator and I was afraid some previous owner had removed it. I was poking around the system a little yesterday. Flame trap is the later white plastic one and plenty of light comes through. I gave it a new air filter shortly after getting the car and didn't notice significant oil but I'll check up on the new one every so often. For what it's worth, relocation wasn't completely a guess on my part. I saw something about a relocation kit a while back and assumed that was what was going on.
