So guys that have tfs valve covers. I am trying to figure out a way to put a better oil filler neck/vented oil cap on these valve covers. I have already got the vented an breather fitting and I figured I would run that on each side with the pcv oil filler cap. My issue is all the ones I am finding are either for stock valve cover or they are threaded. I need one that pushes in the grommet or I guess threads on the valve cover like the vented breather fittings. If anyone out there knows where to find one of these I would appreciate a point in the right direction.
