  • How important is silicone rubber for an aluminum V6 VCG?

    My Toyota 3MZ-FE engine valve cover gasket rear bank is leaking.

    There's a Fel-Pro VS50588R copycat kit, which matches PN 11214-0A010, 11214-20030, 11213-0A010 & 11213-20030 (both banks & spark seals).

    But the material isn't stated, so I can assume it's a nitrile-butadiene
    rubber & not a vinyl methyl silicone (or they would said that it was).

    Silicone is more resistant to higher temperatures and automotive fluids.
