Hi again, still rebuilding my 283 and another question has come up - it's the standard '64 195 HP 283 w/ Roch. 2-bbl. carb. What is the correct original way to hook up the PCV system? Someone before me, in their infinite wisdom, removed/plugged everything - all I have is the rubber grommet at the rear (with a bolt stuck in it) and the 'can' inside. Are the orig. type parts available still? Thanks for any feedback on this.....

For 1964, the parts are very much available. There isn't much to it really.

The rubber grommet at the back of the block should be removed as there is typically a steel 90-degree elbow that bolts there with a seal. From there, you run vapor tubing (not heater hose) up to the carburetor base where there is a PCV threaded into the base of the carburetor. If you don't have the steel elbow, you can mount a newer styled PCV into the rubber grommet and then run vapor hose to the carburetor. In the end, it all works the same.

You draw fresh air into the crankcase through the oil filler cap mesh filter.

The steel elbow Tony speaks of is kind of a unquie item. There is a hole in the center of it for a long (3"?) bolt that screws into the bottom of the hole. I see these on ebay every once in awhile but have also seen them in one of the vendor's catalogs, Ecklands maybe. If you find one make sure to get the screw too. You won't find one at the local hardware store.

Just a side note, the 283 that was in my 62 had that port sealed up with a small freeze plug. It had Edelbrock valve covers with breathers but nothing else, no PCV in the system. There was no circulation in the crankcase and there was ton of sludge built up throughout the engine.
