    So i pulled some bent push rods out of my engine, all of my exhaust valve pushrods are the ones bent.
    So my questions are; Are my exhaust valves floating?
    What else can cause bent Pushrods?
    Now i have the stock E7 heads with a B303 cam
    Thanks for the help!

    If the valve springs arent binding at full lift. Youll need to remove the heads and check for piston to valve contact. Ive never seen a B303 have issues, but there is no telling what someone else may done when the cam was installed.

    There is far more load on the exhaust pushrods than the intake pushrods and this is typically why you see exhaust pushrods bend first. It could be as simple as you over revved the motor, have the wrong pushrods (even though they look origional?) or you had some sort of mechanical failure to cause this. What were you doing when this happened?

    Balancer snapped off? You don't need to disassemble the motor for that. You mean the crankshaft broke? That's why you bent push rods. The end of the crank that has the chain was out of sync with the cam.

    Hate to be the bearer of bad news but you need to take this engine out of the car. The bent pushrods are the least of your worries at this time.

    Nicely broken block. You just purchased this car correct? Block broken, crank broken, cam and crank no longer in sync. He shoots, he scores.
