Aiight Mike. WTF is it called? LMAO!!
PIC is just for a reference. Pic 2 shows EXACTLY what the cap screws into. Basically I overtq'd it and I need a new one. It's the #1 on the exhaust side. It's preventing the valve cover from being secured. It's only being held by 3 of the outside bolts. Before I sell this block I want it PERFECT.
