Hole in engine near transmission with fiberglass coming out?

I don't know why I never noticed this before, but last night I noticed that my 08 GP base (v6) has a hole about 3/4" in diameter not far to the left of the transmission housing. it appears to be in the engine block and to the right of the exhaust manifold when you are standing infront of the engine bay.

What stood out to me as odd is there is a white fibrous material coming out of it that looks like white fiberglass, I touched it and it feels soft.

What is this? did they pack the engine somehow with fiberglass or something else near this area? Why have I never noticed this before when I cleaned the engine bay in the past? I don't remember fiberglass like material sticking out before
 


this isn't the firewall... this is the cast engine block that has this hole in it on the front side near the transmission

Not sure what that port is for, but it just leads into the bell housing area, which has no fluids in it obviously. I'm guessing it was popped out and a mouse may have tried to make a nest in there? I've seen mice make lots of odd areas on cars their homes.

I always thought that hole was used to hold the flywheel from the top with something like this during production, but I have no proof of that.

Nothing should be coming out of there. Chances are that something got pulled in from underneath and is trying to find its way out. You could always take off the starter and look up there to see if anything is trapped.
 
Is your flywheel cover installed? If not you could have picked up something off the road and it got chewed up in the bell housing....????
 


I had a t-stat housing similar to that on my old 94 Grand Am, 4 cyl 5 speed. you opened the radiator cap on the housing, pulled out the t-stat, installed the new one and put the cap back on.
