So I've got a spare intake I've pulled apart, cleaned up, etc. Now I'm about ready to re-assemble and had some questions about the hex screws underneath the windage tray/oil seperator/whatever it's called.
The middle one seems to go directly into the intake. The 4 in the corners butt up against two ~1/4" holes underneath (EGR? Not sure).. Question is, what exactly are these for, are there torque specs, and for the ones in the corner are they an adjustment screw or do they just need to be torqued down?
