Crank hitting piston head

[acurac27a]

I finally found what was making the clicking noise from the crank pully area, the piston directly beside the pully is hitting the crank its self.

you know the counterweight-like big lobes on the crank, well when i turn the effected piston far as it will go down the lobe fits into the chunk that was knocked out the piston, so obviously the piston head was cracked by hitting the lobe and and constant clicking sound while running it is constantly tapping the piston.

what would be the most likley cause of of this? the crank and rod arent visibly bent, ill try to take some more pictures of this. anyone think the car is ok to drive till i get the money for a new engine? it clicks alot like a valve tap and it stalls occasionally, basically only running on 5 clyinders

that rod looks way to small for that piston....unless the skirts are really long.

Get some pistons w/ smaller skirts or take it to a machine shop to see what they can do....

that first pic up top isnt my piston, its just to give an idea of where the skirt is broken, the poor quality pics are of my car since i only have a camera phone.

here is a actual pic i just took of the crank lobe fitting into the broken hole in the skirt. its almost a perfect fit so obviously the lobe broke the piston skirt. im just not sure how the piston is contacting the crank. I'm just a weekend mechanic and want to tackle this.

You're going to need to take apart the engine and check out the damage. If it's just the piston that's messed up, then you're lucky as hell. But I doubt it's just your piston since it obviously made contact with something else. I'd be surprised if you didn't bend a rod, since you said you hydrolocked the engine in your other thread. What engine is it btw (since you mentioned it's a 6 clylinder engine)?

it is a bent rod, after pushing the piston to TDC the cylinder walls look good from what i can tell, unbolted the rod from the crank but there isnt enough clearence to pull it out past the crank, i really want to just put another rod in without pulling heads for this POS car, im guess im going to try taking the rod pin out the piston and see if i can pull the rod out that way, i dont know if i can, just trying to be ghetto, never pulled a head before and seems like alot of work for this old car
