Hey squad, I have a 1994 Nissan 300ZX NA Coupe, and had something awful happen yesterday, pulled valve covers for new gasket and some other repairs and I was holding the valve cover screw and it bounced perfectly into the hold underneath the Camshaft. After about half a second I heard a "Clank" as it landed somewhere inside. This is the driver side, I tried fishing it out with a skinny extended magnet and don't feel anything, I also tired the Hole on the next section over to the right. I ordered a snake with cam and magnet, but wont be here for couple days. Anybody have any ideas on where that hole would lead to? I attached pics as well thanks for any help.
