    Once again, looking to the HAMB for help. The sbc in my truck has some old finned aluminum Corvette valve covers. The vents were originally connected to the air cleaner, but I'm looking for a cleaner option.

    Ideas or pics anyone? Here is a pic of my nasty old engine.

    Thanks in advance

    Isn't it a 5/8" hole? can't you just put a breather on the cover? my FLAP store had one (mr gasket I think) until I find better

    Heres what i did to clean up my engine compartment and to keep all the oil spit off the covers i ran an external stefs breather with AN fitting connected with a 10an hose routed it out side the engine compartment. Canister has breather on it still have to hook up hose in pic!

    Yeah, thats the problem. I found the Mr gasket and similar, but they seem like they are intended to mount on a pipe and i'm afraid it'll be flopping around in there..

    Maybe a pipe nipple nutted to the cover then clamp the Mr gasket on? I'll have to take a closer look at them.

    Nice - too fancy for my truck given it's overall condition, but excellent install.

    Whose breather did you use? That looks clean and stable.

    I must say I have never seen a universal flex hose in full extension like that before.

    Ok this is the PCV valve in the grommet on the valve cover. The hose should go to the base of the carb and not to the fender well someplace.

    The elbow is where the air enters the engine. You can get away with a standard type breather on this side as a place for the air to enter the engine.

    I can't help with a breather or a part number to fit that size opening but I'm betting that they are out there. Pull the elbow out and measure it to find a push in breather that fits the hole which is smaller than a lot of the push in breathers.

    here's the same valve covers--pass side has PVC to base of carb-dr side has a breather-I use the ones without holes on the bottom side underneath to prevent oil seepage--made by Sunspec but there are others

    Dont get me wrong. When he said he had a 47 Hudson truck and would trade, I lit up like a flashlight. I love those trucks. Used to know where one was and thought it was the coolest thing.

    Yours is way cool.

    Olescrounger - Perfect, thats the explanation I needed. I'm pretty much an idiot on sbc motors, among other things.

    Gasser300 - no worries, I didn't take you comment the wrong way.

    Thanks for the help guys

    Chevrolet had it right in the early 60's a filler tube/breather in the front of the intake manifold, a PCV valve in the rear of the engine and plain valve covers. It works for me.
