Non-Miata engine rebuild question
I have an engine that has been sitting for a long time, outside, uncovered. It looks as if at some point a whole lot of water leaked in from somewhere and filled up all the cylinders with water. It does not look like coolant. When I pulled the head off clear water just poured out.
It looks like it has been this way for a long time. If I dissassemble and take it to a machine shop to get worked over and cleaned, is there hope that I can just rebuild this engine? I've never really worked with an engine that had rusty internals.
This is a v6 out of my 94 chevy. I would really rather rebuild this and have a practically new engine then pick a running one up from a junkyard that may need to be serviced. But this engine is in very bad shape

I will get pictures tomorrow. I had to laugh when I pulled the head off so much water came out. I'm wondering if the oil pan is filled with water too. Tomorrow should be a fun picture day.

I would say do not pull it apart to far. I would drain oil pan of any water it has then take it to the machine shop as is and let them disassemble. This way the machinist will know where every nut and bolt came from and where they go.

I still need to get pictures... but I think there is hope.
I think worse case I bring the bare block to a machine shop, have them bore it out to get rid of the pitting if there is some (looks like it might not, just surface rust) and then put in some oversized pistons.
I'm gonna flex hone it out next weekend and see what it looks like and make the call then.
Really looking to spend the absolute least amount of money on this. It's a Chevy truck engine, I don't think a liters of water in the cylinders is gonna stop it
