    You could possibly hear a knocking/ticking. You could figure this out with a leakdown test. Undo your intake and perform test...if you hear air escaping from the throttle body...you have a bent intake valve and if you hear a slight hiss from the muffler...it's an exhaust valve. You can also check by holding a lighter (no wind/indoors) and seeing if the flame blows.

    a compression test could also tell you if you have a leak...but you won't be able to pinpoint it...unless you do the leakdown test.
