Is smoke coming from the outside? Or did you have your air cleaner off?

There are 2 seals on the CDR, CDR to Intake and CDR to valley pan. One of them could have dried up and broken letting the smoke out.

cdr is like a pcv on a gasser. pulls crankcase pressure into the intake.

i woul dfix it just because if u see smoke coming out, that means there is an open hole into the motor, for water/dirt to go into.

Pretty sure it's a dealer only item. I work at a parts store and haven't been able to find one.
