Somewhat related: The stovebolt sixes have they're own smell that is different from other engines I have had..My kitchen has a door that opens to the garage and some years ago I left it open while starting my truck and backing it out of the garage..the house stunk for almost a week..if it was a new car that smell would have been gone in 10 minutes..permeates clothes fabric..just nasty..I started a thread about it here:
