1995 Hole In Block?
 

Hi,

I am new to this sight and have a question about my miatas block.

I am in the process of rebuilding the motor and when I took it apart a noticed a rather large hole near the #4 cylinder oil squirter. I didn't notice any large chunks of metal fall out or see any other damage besides the hole. I have seen some other pictures of this same hole but I don't know if it is supposed to be there if it is a common fail point. Is this supposed to be there or does this mean that my motor is ruined? Any information would be helpful. Thanks.

I'm pretty sure I posted about this before, and many others.
Casting ugliness...nothing to worry about.

That's an oil drain hole.

OK cool. Thanks! This is my first build and seeing this kinda worried me.

Don't feel bad, it happened to the best of us.

I had the exact same reaction when I tore my perfectly fine running 28K '04 down. Was about freaking out till I did some google searching and saw a lot of pics of the same rough hole in the casting.
