Crankcase Breather Tube

[Deleted member 39301]

You know the tube that inserts into the main intake (large) hose between the throttle body and air cleaner? Where does the other end of that go?

(No guesses please.)

So would need to know the engine, and year, of your Buick.

The hose pictured is for the 2002-2005 Buick Rendezvous with the 3.4/3400. That breather hose would go from the front valve cover, to the intake tube, to the rear valve cover.

Its a different hose for the 3.5/3500, and the 3.6HF engine.
