Pistons hit the spark plug.

[3aG1e_7a1oN]

After taking my spark plugs out, i knew there would be problems when I looked at the electrode and it was gone. This is the damage of my spark plugs and valves hitting my pistons. I have a spare head, so I was wondering if these pistons were usable, or if they're garbage. I searched, and there was a thread about the pistons hitting a spark plug and people told him the piston is okay to use. I also searched for valves hitting pistons, and some pistons looked worse than mine did and people said its good to use.

The #1 and four had some but minimal damage. Waiting on your guys's opinions to say whether I should junk the car and strip it, or if its good to rebuild.

Ouch... how did this happen? I wouldnt use them but thats just me though

Your valves did that, not the spark plugs. The valves are what also mangled your spark plugs. Looks like your timing belt / balance shaft belt went and took out your valves -- quite common. I've seen worse actually, but it's time for a rebuild or different engine for you.

i definantly would not reuse those pistons your just asking for trouble. just think that piston could come apart its gonna be alot weaker when its all beat to hell like that.

At least you have pistons left. Some people don't end up as fortunate. Dump those pistons in the garbage and get some newbies. Also check the surface of the cylinder walls for any damage in case.
