1991 Ford Ranger, 3.0...flat tappet or roller cam?

[kevinrca]

Hi Everyone,

I am new to this group and I would like to know what type of engine my Ranger has. I have a 1991 Ford Ranger and it has the 3.0 Liter Ford Vulcan engine. If in fact it is a flat cam, I have recently learned that I need to add a ZDDP or zinc additive, does anyone know about this and if so, how much? Any recommendations?

Thank you!
