Absolutely! A straight hose would never work and fit like a molded hose. The correct pcv hose has a molded 90 degree bend and is secured with a special hose clamp. Here is an example on my '69 SS350 engine (*note--it is the same one that is being sold on ebay and HBC)
Hope this helps. Have anymore questions about how to critique that engine bay just PM me.
