Damaged 1.8L Block
I was tearing down my '94 1.8L block tonight cause it has been burning oil badly. I knew cylinder 4 was the culprit figured it was just the rings. So I take it apart and looks like cyl. 4 piston is missing some pieces, but are no where to be found and no damage anywhere else. But as I look into the block on cyl. 4, there seems to be a big hole and is has some jagged edges but I cannot tell if this is supposed to be there or not. Does anyone have an idea if this is damage to the block or supposed the be like that?

LOL, car never got tuned really, I bought it from a friend as he got fed up with the car. So I compression tested it and cyl. 4 was crap, yanked it out, this is what I found. So I am not at all surprised. But I got a whole supercharged miata and tons of parts for cheap. Now time to build it right.

Anyhow, I will possibly be looking at replacing the valves anyway, but I am looking at everything for any damage or needing replacement.

I don't see missing pieces, I see melted pistons.
I also don't really see the massive det sav was talking about; maybe on #3, but the edges and squish area's of the pistons look pretty solid.
