hey man same thing happen to me 1 month ago =( .freaking cold air intake, i tried to turn the car on after that happen and all i got is a loud clicking noise . anywayz i finally stopped being lazy and removed the head today im almost 99% sure its a broken rod cause my head is fine so just look into getting a block, also all you gonna need is rods buy some eagle rods and your good and back on track oh and by the way make sure you remove your head also cause i poured tons of oil on the head and change the oil on it about 4 times to get the water out and removed the plugs but when i took out the head today i found tons of water in the valves coming from the intake side and tons of water on the intake manifold. just be careful dont wanna blow your new block again.
