i wouldnt say its that simple henry, i did it when my PCV grommet broke also and fell into the housing. i was using a pocket screw driver to pull it out and was on my last part when the screw driver shaft fell out and into the valve cover (so now i def had to remove the valve cover) its not so much a hard job but its very time consuming ,tedious job ESPECIALLY the drivers side as the wiring harness is really in the way and you have to remove so many things just to get the valve cover off....hell i had to go buy some swivel or a universal socket to get to those 10mm bolts out

 

I admit the OEM pcv is thick. Had to use special fitted pliers to yank it out. Lucky me i didnt crack my gromet. Installation is easy though.
