Sometimes it may smell like gasoline if you have worn out cylinder walls or piston rigs, and the crank case oils are receiving "gasoline poisoning".

But if it is the mechanical fuel pump is really leaking into the cylinder head, then there would definitely be a noticeable amount of fuel mixed in there that you definitely would be able to detect.

Might I also note that this fuel pump issue only applies to Carbureted engines; Is your 1985 Carbureted of Injected?
