98-02 LS1 Helix Mount Valve Cover Breather


Model Number: MBR0003

Crankcase pressure has long been considered detrimental to engine performance and gasket sealing. As pressures increase through performance and age gaskets often begin to leak. By venting the crankcase to atmosphere those pressures are greatly reduced. Metco valve cover breathers are CNC machined from 6061-T6 aircraft grade aluminum. Other features include:

  • Positive filter engagement, will not blow out as crankcase pressure increases, yet easily removed.
  • Fits OEM valve covers with no modifications, easy to install.
  • Cotton pleated chrome-topped filter, washable.
  • Polished to “Show-Quality” lustre.
  • Includes high quality seals for leak free engagement.

    This wont fit if you have a shock tower brace…and i was told the only way to put it on is if i took the valve cover off…i tried putting the top filter piece on the plastic oil filler neck with a hose clamp, and half of it melted 🙁 i would stick with just the new pcv valve and oil catch can ;P

    Def. DOES NOT fit with strut tower brace. NO WAY. Was told by support to take off plastic elbow that stock oil cap screws into which can only be accessed by taking valve cover off and release plastic tab on underneath side of cover. Other car with no strut tower brace, it doesn’t seal properly… not happy. See for yourself
