may have run out of oil that thing that hit could have been your oilpan

Either valve and piston are damaged by timing belt slipping and causing everything to be out of sync... Timing belt must be really worn.

OR

YOu broke a piston rings.

SO IS IT SAVEABLE ?!?!?!?!?!?!

only way to find out is to dig in there and check it out.

Go check your oil, sounds like you fried the engine running it with no oil. Probably punctured the oil pan with the thing you hit in the road. Sorry more than likely you have screwed that engine pretty badly, but remember: everything is salvageable with the right amount of money.

If it was knocking real bad and then it died and wouldn't run again, added to the "white smoke" coming from your valve cover, I'd say you probably either cracked a sleeve (if the knocking was bad enough), ruptured the head gasket (and maybe hydrolocked) or cracked the head (valve/piston contact ).

What does the rancid smell smell like? How thick and cloudy is the white smoke from your valve cover? Are you sure it's not blue? Can you describe the knocking sound better? Will it crank at all? Do your accessories work?

Get back to us with more info. Good luck.

yea take that thing apart and check it out.

A knock that rapidly progresses and causes a loss of power is usually a rod knock. The loud clunk and puff of smoke may have been the rod being thrown. Like the others said, pull the motor apart and inspect it. Inspect the outside of the block for cracks or holes where the rod may have come through.

UPDATE

pulled valve cover:

timing belt in one piece.

That would be your starter turning the no-compression bottom end...therefore you have accomplished absolute 0. I agree that it sounds like rod knock. Were you watching the pistons when it happened? Were they all moving? Did one of them look busted (the rod, not the piston)?

i didnt take off the head, only the valve cover. i put it all back together and tried to start but only for like /5 seconds cause it make a LOUD SHRILL FAST knocking loud sound. that might help ?

toolowsol

my money is on a broken rod... did you check the block all around and make sure there are no holes??? Also, remove the spark plugs, stick thin dowel rod down, and turn the motor, the rod should move up and down in every cylinder, meaning the piston is working

daklown

so what happens when i push a dowel down a cylinder with a broken rod ?

so say a rod is broken, and i didnt penetrate the block, could i skate by with rods and new pistons if my cylinder wall is somehow okay ? and, what are the odds that it is ok ?

jumpmann23

like i said only one way to find out. take off the head and check
