What the heck did this?

Hey guys, I sold my PI intake and heads and what not. I was taking the PI intake off the npi heads on my car and I noticed this before I put on my npi intake again.

The water jacket on the drivers side has the big chip in it... I don't know what could have caused it... its so smooth and has some spots look like something struck it below the chip... anyone know how this could happen?

That looks like a bad spot in the casting that let loose due to a quick temperature change. There really isn't anything in your cooling system that would strike it unless you hit that spot with a pry bar when removing the intake manifold before. It's just such a clean break that it actually looks like how arrow heads were made out of rocks a long time ago. I think more of an issue would be where that piece went, not what caused it because it's going to either block something or tear your water pump to shreads.

o well, I rather it get the water pump than having to pull the heads off... cheaper anyway...

That looks like a pretty big piece that came off. Hopefully it finds a low spot somewhere and lays there for the rest of your motor's life and causes no problems.

lol yikes :crybaby2: I don't know, wonder where it ended up though lol, it went down that hole i think b/c of the scratch or ding marks on the bottom sides of it.

I don't know man, but I am still sticking with the idea that there was a problem in the casting. You could'nt knock a chip off of your block with a chisel that clean if you wanted to.

tape off your intake ports. remove the water pump. empty your cooling system and use a water hose and flush the entire system. hopefully the metal flushes out. little work but maybe save some pocket change.
