    Broken rocker, but timing chain is good....help, help, help!!!

    Ok, so i got under the hood popped off the distributer cap and turned her over, the rotor turns. Ok, no timing chain break.
    So i proceed to start moving hoses and vacuum lines got the valve covers off and a broken lifter comes falling out. Ford, in the casting of the lifter there was an air bubble left inside the metal in the exact spot where the break occured.
    It doesn't seem to have messed up the crankshaft or bent any valves. I am going to be doing a compression test to make sure they are good.

    But i'm still a lil' confused, the break still doesn't explain why i lost full power when the break occured, the car was still running but i had no power. In theory i believe the car should of still been drivable. Even though i know if i would of kept driving it there would of been serious problems (Almost glad it died).
    And also it doesn't explain why when i tried to turn it over after i got it towed why an air gas combo came spraying out of the carb.

    Ok, so i know one thing i need to fix, but i'm still a little stuck on what i need to do after that to get her back up and running.

    Why did after the break occur could i step on the gas, but the car would go nowhere?

    Help me out here guys!!! Gimmie some advice

    Okay, I think you are missing some things here...

    1: A broken lifter won't fall out into your hands when taking the valve cover off.

    2: Just because the rotor spins in the distributor, doesn't mean your cam sprocket hasn't broke teeth.

    So, please clarify that you have laid eyes on the cam sprocket and what, exactly are you calling a "broken lifter" that fell out of a valve cover.



    Edit:
    The lifters are in the block, well under the intake manifold and valve covers... You won't find a broken lifter without at least taking off the intake, and it wouldn't "fall out" without removing the oil pan, and would be in many small pieces at that point.

    I think he means ROCKER fell off.

    That's what I figured.
    It was pretty clear, but he is so frantic and posting multiples of the thread while we are trying to help, that I thought a reality check might be in order.

    Kinda like slapping a hesterical person back into calm thought.

    Ok, my bad. I'm not really super car savy. So when it gets technical i'm an amatuer. Me trying to fix this car is the first time i have ever done so, so i'm kinda learning on the fly.
    I know i'm not as car smart as the rest of you, so bare with me if possible i'm still learning.

    Damn, faulty rocker arm with an air hole

    Any ideas on what might of caused the gas/air combo spraying a foot out of the carb after the rocker arm broke when i tried to turn it over?

    Any ideas of why i lost power when the rocker arm broke (pressed gas but car wouldn't move) and after it broke i could no longer fire the car up.

    Any thoughts???:huh:

    Once you do any of these things we say may have happened, the timing gets all messed up. I don't mean timing as in "advanced 10 degrees", I mean valves opening and closing nowhere near the time they need to to work with their respective pistons.

    When you jump timing, either by skipping a distributor tooth, cam tooth, etc, the valves are now opening and closing when the piston is somewhere way off where it should be. So the piston may be coming up when the intake valve is open, and that will push the gas/air mixture back up into the intake, and out the top of the carburetor. It just totally messes up the timing between the valvetrain and pistons, so you will get all kinds of weird backfires, misfires, popping, etc.

    Hope that helps you understand.

    You will need to take both valvecovers off, mark on your distributor where each spark plug is located, pop off your distributor cap, pull all your spark plugs, and rotate the engine by hand at the crank pulley with a socket. You will need to see where the rotor inside the distributor cap is located, and watch how it moves when you rotate the engine (by hand). You will also need to see which rockers are moving and in which direction they are moving compared to where the rotor is facing. This will give you an idea of how "off" the timing is, and will also let you verify that the rotor moves consistently with the engine all the way through a couple of revolutions.

    When the rotor is pointing at #1 spark plug, both valves should be closed, and appear level. I will bet that on one or more of your cylinders, it is pointed at one of the plugs and one of the valves is open when it shouldn't be. Write those down and we should be able to help you out from there.

    For example. when rotor is at #1 plug, write #1 both rockers up, then rotate to #2 and write #2, intake up, exhaust down, etc all the way around and let us know what you find out.

    If you hit a solid stop when rotating it. DO NOT MOVE IT ANYMORE! Piston may be hitting the valve which will be the bent valve issue we said earlier if the chain has broken or jumped too far.

    Hope this helps you get started, and hope others can chime in to clarify or further expand (or correct) what I have written here.

    This is the kind of experience that will help you better understand how the motor works and you will get into it far enough to learn some pretty valuable skills.

    Take it easy and slow, it will take a good deal of time to fix diagnose and fix this, and it might end up costing you a lot of money depending on what may have been broken.

    For quick and easy check if the timming chain has jump time . Disconnet the coil wire from coil Turn the engine with the starter Put your hand over the air horn on carb like you are chock it if the air suck in engine is close to being in time if the air blows out the timming chain has jump out of time .
