Review on Stant 10071 Oil Filler Cap by Bomba Ton

Perfect for my 77 F150 with 300-i6. There is a hole cut in the top part and there are two bushings for installing PCV hoses etc. If your factory cap has a hose coming out of the center this is what you need. Note: I had to buy a PCV socket because the socket would not come out in my original cap. By the way, $3 at O'Reilly.
