After installing a new engine fan shroud (after reviewing all related threads I could find for fan shrouds on 993's and getting the part from the local dealer), I started the car and everything seems fine. I put my hand behind the shroud while it was idling and noticed a little bit of air blows out the back bottom of the shroud, but not a lot. Is that normal? Or should it be completely blocking any air from getting out...? Thanks for your help.
