This is the rubber elbow that your PCV valve sits in, on the backside of your valve cover (driver side rear corner). 
 
This fits:
 
1984-1987 2.2 Turbo I engines
1989-1990  Chrysler Maserati TC with 16v DOHC 2.2 engine
 
Note: If you have a 1988-1992 Turbo I engine, you will need a Turbo II elbow.  That part is located under our Turbo II section.
