Where is the crankcase vent on your passenger side valve cover (front or rear)?
I am replacing tall chrome covers that came with the car, and it's port was on the rear. But nearly all of the pictures I have found show the port to be up front, closer to the TB just like the TBI trucks have.

 

It really doesn't matter. GM ran em toward the back on carb and early TPI cars, TBI too I'd assume. Later TPI cars they're toward the front.

 

Cool, so that little contraption I assume they did, to extend the hose, isnt GM factory.

 

Right. The molded part is, it's late TPI and not reproduced, so don't throw that away. A stock TPI setup with the rear location has a long steel tube and a short steel tube, with rubber couplers. It runs between the valve cover and injectors.

 

This hose is a good replacement
