Where does this port lead to in the head?
Hey guys, I'm doing the fuel injectors on my 86 trans am 305TPI right now. I popped off the passenger side valve cover to gain access to the lower runner bolts and did a quick check and saw the port closest to the radiator has pieces of a cork valve cover gasket jammed up in it.
where does this lead to and about how screwed am I? Gonna use tweezers to remove what I can but I'm afraid some probably already made its way down the passage.
Trying to upload pics but it wont let me click the insert image icon, bear with me for a second.

Just an oil drainback hole. Even if there was a piece of cork covering the hole, oil will still find another passage to get back into the pan.

I haven't driven the car since July of 2016. I was pretty happy with how clean the rockers were. No gunk or sludge build up. Gonna give it an oil change once the spring comes around

Figured that's the sitting/winter effect. I used to get that when I lived in Montana. Block heaters and cardboard in front of the radiator used to help in those -30F winters.
