Being that its a block FOMOCO logo my guess is that it is for a 1967 6 Cyl. closed crank case ventilation system. For 1967 I think the nipple sticks out straight on the 6 Cyl engines and for the V8's its an elbow nipple that sticks up.

Sorry Jim, I embedded the pic instead of making it an attachment, sometimes that doesn't work. Here it is.

Does anyone know the specific application for this oil breather cap? This is an original cap (not a repop) which as you can see has the block FoMoCo stamp and was originally black. I just cleaned it up and repainted it. It's a push-on type. I know it's for the closed emission cars but would like to know what year(s), model(s), engine(s), etc. Thanks, Dave ________________________________________ PeoplePC Online A better way to Internet http://www.peoplepc.com
