Is the line blocked off or have you been sucking raw air into the valve
cover? In that case what Mike said won't happen, but you still need to get
a line in place. Doug's idea to use tape is a pretty good one. I assume
you are talking about the big CCV line to the air cleaner, not the small CCV
line to the intake manifold.

As Earle mentions, it's the small one that is the really important one,
the large one is the intake.

Here is a site with the part numbers and prices for the various tubes.
They are not too expensive.
