Thanks, Roman. That's interesting. I could swear I've seen recommendations from Americans that it takes 4.5 quarts. Maybe they were referring to the Brit quart? Anyway, I was starting to think maybe the p.o. had used a larger oil pan. All of the illustrations in the parts books shows the drain plug on the side of the pan, but mine is front center. I was grasping at straws, I guess. Anyway, thanks again for the help, Roman.
