What's this hole? (have leak and not sure from where)
I'm getting what looks like maybe coolant pooling up a little bit at the very back of my block in a valley below the PCV valve and at the bell housing....and it's enough to slowly drip down the side of bell housing, etc. But right next to it is a hole with threads in it...but it's very hard to see back there and before I pulled everything off I wanted to see if anyone knew.
The coolant gets into the hole...but it could just be I have a gasket leak and it's flowing from that little valley into the hole (which is my guess). So #1, what's that hole and should it be plugged? #2, what gasket would be leaking back there typically? My passenger side head maybe?
