67 C10 327 PCV Question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

67chevylongbed · 10-14-2009, 06:13 PM

The truck was originally an Oregon truck so I don't think there would have been a PCV system on it originally. There is however a hose running from the back of the intake manifold and laying on the inner fender with exhaust coming out. Where is this supposed to be connected to, or can someone just show me how to hook the PCV up properly. It has an aftermarket 600CFM Holley 4 barrel electric choke carb.

The valve covers have no oil ports. The oil port is in front of the intake manifold.

Thanks ahead of time if anyone can help me out.

does the truck have power brakes? are they aftermarket valve covers or orginal?

Does it have an auto transmission?

That is a Road Draft tube.

I have a 67 C20 that is original to oregon with a 327. It has no provisions in the valve covers, there is however a tube that comes up from the rear of the block with a PCV valve inline. The other end connects to the base of the carb as usual.

So we cant post pics at the moment...but if you look at this thread second pic you will see where the PCV valve goes. That would be the large hose just behind the carb carb mounting surface. My truck is about as factory original and unmolested as you can get around here, so I have no doubt it is the original setup. Hope this helps....

Thank you for the help.

They are manual drum brakes, so no vacuum is being used from the intake manifold for the power booster. It is a manual transmission, stock valve covers. Sorry I can't take a pic at the moment.
