I'm with you, Scrap. I had a '56 Chevy 235. Never smelled anything on the highway, but in town I'd get that sickening odor....especially when it was hot outside. I used the pcv valve off of a military M-37 and sealed off that draft tube. engine ran the same, but no more odor in town. I drove that sucker 210,000 miles, with an in-car set of bearings, rings, valve job and gaskets at 160,000 miles. It was still running good when I sold it.
