Yes, I have an oil fill pipe in the front and that has a vented cap on it. When I bought the truck they had the valve cover PVC connected to the bowl vent on the Holley carb, so obviously there was no venting going on. It was making quite a mess of everything, not to mention all the fumes coming into the cab because of all the missing grommets.

I connected the PVC valve to a port on the intake, and will explore further using that port in the back as part of the venting system.

Thanks,
