    Question '54 322 Blow-by

    Hi folks,

    So I got some concerns about my old nailhead.
    It has some serious blow-by issues from all openings: breather, valve cover bolts, dipstick,...you name it and it blows. :/
    It doesn't burn any oil, but manages to lose about 1qt every 200-ish miles.
    So my guess is it's time for a rebuild. It has 96000+ miles on the odometer but my guess would be more 196000+...

    The plan for now is to pull one of the heads and see how bad the wear is and go from there.

    Now since I am in Belgium parts are not that readily available, so I want to get everything right from the first time.
    Is there anything special to consider for a basic rebuild? I would guess: new rings, new gaskets, leave the crank in place,...
    (from googling I would think centerville-auto is a good place to order everything?)
    How badly will a '54 nailhead usually be worn out after such mileage?
    If the block has to be bored will I need new pistons for sure?

    It already has a new cam, lifters, pushrod, and rockers.

    I think I might be too optimistic on how this is going to go, so any and all opinions, suggestion, ideas,... are welcome!



    Grtz from Belgium,
    James

    Cool Blow by

    James,


    Sounds like you you have a pressure problem .
    Back in the 70s someone came up with an idea to remove smog from our cities. It entailed adding about a 5 dollar part called the PCV valve,!!!!
    I can help you. The first thing I would do is remove the smog tube from the back of your engine and install a PCV valve with a vacuum line to your engine.

    This should save you a lot of headaches, especially since you are talking about removing heads!

    50s car with 100,000 miles are almost certainly worn out. I would expect you will want to purchase new pistons. I would also rebearing the crank and change the cam bearings.

    Thanks for the insight, I've been reading on PCV-systems for a bit and think it's worth a try before I do anything else.

    So basically I should run the vent tube that goes to the underside of the car through a PCV-valve and send it through the engine controlling it with vacuum...2 questions:
    1. Does it matter where I run the vacuum line from?
    2. Do I need to put a different cap on the filler up front?



    Thanx,
    James

    A PCV valve will not remedy the kind of blow-by you are describing.
