Just doing an intake R&R I was wondering if I should use a selant in addition to the rubber gaskets or do the gaskets seal well without any additional sealant

Thanks
Sean

 

gasket seals go on dry

 

good rule of thumb,
1 piece gaskets receive no additional sealant,
multi piece require some sealant at joints.

 

Note if your doing the intake i would add some Honda Bond to the oil fill spout O ring and the base, this part will leak due to the plastic parts melting or bowing,
the Hb should add some seal to the O ring, also consider getting the 928INTL oil fill block off plate
