Starter re-watching some of the older Roadkill episodes (as got MotorTrend subscription & watched near everything else
) and noticed when the Crusher Camaro had the blown 489 big block, they had zip-tied terry towelling rags around all of the the breathers.
But then I looked up more Google pix & they were either not there or had this dealio:
In any case, really doesn't seem to be an uncommon thing on BBCs the more I look into it.
I wonder if this towelling is a 'good enough' solution for my very, very rare dragstrip & dyno runs (only time blow-by happens)?
