    Could someone please tell me what these parts are?

    1 goes into the back of carb
    2 goes into the air cleaner

    I need the gasket on the valve cover for 1 and
    the plastic piece (one way valve?) for 2

    Number 2 - I found the gromet on my 71 in the Help parts at Orielly Auto Parts. I took the old one with me and just looked at their gromets until I found one close.

    I *think* #1 is the PCV valve (positive crankcase ventilation). It allows the crankcase to vent into the oil bath air cleaner. Is it a silver metal cylinder with a check-ball inside? If functioning properly, you should be able to blow air through it from the bottom (inside the valve cover) to the top, but not the other direction.

    Edit - I just noticed that you say #1 goes to the carb. It shouldn't - it should go to the air cleaner. Running it to the carb could put oil into your fuel. Also, mine was metal, on an April 1971 CJ5, rather than plastic.

    If I'm wrong, someone will correct me.

    1 is the pcv valve and 2 is the breather. 1 should have a hose that goes to the intake manifold or base of the carb. #2 should go to the air filter housing. Both have rubber grommets in the valve covers that get hard or cracked with age. Readily available at most parts houses.

    That is beautiful. Where is your ballast resistor?

    for number 2 you can substitute a local breather filter, but it won't look factory.

    It is a super clean engine compartment, not mine though I pulled it off this site a long time ago to show me what mine is supposed to look like. Figured someone would recognize it as their own. Autozone has no idea what that part is. I wouldn't mine having the edelbrock breather filter but what would i do with the opening on the bottom of the air filter.

    here is my beautiful engine

    There are breather filters that have the nipple on top like that. Most are cheap chrome plated jobs but there are others out there if you hunt around. Ford used them that are similar as did other mfg's

    I just covered mine with duct tape. It has held for 15-20 years, can't remember how long. If it is a round hole you can get hole plugs at any hardware store or mcmaster.

    Just a bit of clarification-the PCV valve is designed to draw oil fumes & blow-by out of the crankcase & burn them through the engine. It draws clean filtered air from the tube on the air cleaner, pulls it through the engine, and then into the intake.
    Also, part #2 in your pic is metal, not plastic. If you're not going to run the stock air cleaner, you can run a breather type cap in the valve cover as posted above, just so you have something to keep dirt from getting into the valve cover.

    You definitely need filtered air going in to the valve cover, where the blue funnel is. The factory air cleaner supplies that from the filtered air going to the carburetor, as seen in the top photo. You can do the same thing by punching a hole in the top cover of your air cleaner, and sending it to the valve cover. I would run the factory air cleaner, if I had one. (Not a fan of the K&N filters - would prefer a big paper element with a foam wrap, for a Jeep, or the original oil bath air cleaner)

    Plastic breathers were later aftermarket replacements. Shoot me a PM, got a real one you can have for shipping.

    now that I actually understand what the breathers do, the pcv goes into the steel part at the bottom of the carb, then it goes into those 2 holes on the manifold and i assume the oil vapor trickles down back into the oil bath. Problem is my two holes are sealed up with junk, i could only get one opened up. The PO actually used a carb/manifold gasket that closed it off. Can I remove the pcv and just put a breather on both sides?
