Breather tube. What did I win?


#3

Unless that Lincoln dates back to the early '60s, it doesn’t have a breather tube.
A PCV system was mandated, beginning in–I think–1963, so I would say that the part in question is the PCV valve and its related “plumbing”.

The breather tube or “make-up air” line is connected to the air induction tube between the air cleaner and throttle body. The PCV line is connected to the intake manifold where vacuum is present.


#5

I named mine “Phil.”


#6

Oil filler cap.

That’s the PCV breather tube. The PCV valve is in the passenger side valve cover and the breather tube connects to the driver side valve cover.
