If you are at the point of saying it "stinks", not "It has a little smell of" -- oil smoke, gas, hot grease etc.
Something is wrong.
Picture walking down a down town street with cars and trucks of that age parked at the curb and driving up and down the street. Do you think they would all "stink"?
Having owned, garaged and worked on a lot of antique and classic vehicles I can say none of them ever smelled bad, let alone stink.
What are you smelling? Does it only happen when hot or is it there days later?
