      PCV? or no PCV?

      my engine builder told me not to run a pcv valve on my motor because its more of a race motor then a street motor. just sounded weird to me and am looking for opinions.

      the set up:
      383
      10.5:1 cr
      ported brodix aluminum heads with 2.05 1.60 valves
      hydraulic roller cam 540-540 lift. 236 248 dur.

      1969 Camaro under construction.
      1967 firebird. 6.0/t56. Ridetech stage 2. Moser 9 inch. Forgeline wheels.(SOLD)

      The PCV aids in sealing your motor along with removing harmful moisture build up. Unless it is a trailer queen I would suggest running one.

      PCV is good for your engine, and costs little or no power. There is no good reason not to run one.

      I would run it unless he has something else that'll work.
      For instance, you could run a vacuum pump, which will do what we recommend using the PCV for.

      PCV is not just the valve and line from the valve cover to the intake manifold. It also means a filtered air supply so that there is ventilation (filtered air in, bad vapors out). Usually it's done with filtered air coming into one valve cover, and the PCV valve on the other.

      A vacuum pump setup that also supplies filtered air would be fine, I guess. I've never seen one like that.

      Use a PCV system.
      Especially on a street car.

      Guaranteed ring flutter and oil consumption issues without. Lady at work wont advance her timing enough, carbs out of wack, claims it has big cam but will barely single track spin a tire,header mufflers ending by trans, ie no pipes. Oh and 2 vented caps on valve covers.
      Some times it just doesnt pay to try and teach stupid.
      And I know your smarter as this unit will driven on the street i am sure.
      Use Pcv it wont hurt but do make sure your pcv valve side has good baffle.

      NOT a race motor ... that is a mild street engine. Use a PCV.

      Is your engine builder a friend?

      If my engine builder told me to do something then I would do it without thinking twice. He's just that good.

      If you're double guessing your engine builder, you might consider a different one?

      I mean that in a nice way, because you're entrusting a lot of money to an engine builder, and he's supposed to know more than you do (or anyone else for that matter).

      the reson i took my motor to this particular builder is because they are the best around my area. but i just always heard that a pcv valve should be ran. it just confused me a little bit.
