Be careful with RTV... its the most mis-used and over-used chemical in all automotive applications. RTV should only be used as a filler of gap... example: intersecting corners (oil pan, intake); ok to use in place of front/rear intake rail gaskets, but again... be careful.. not too much.

NEVER apply RTV onto rubber gaskets... it then acts as a lubricant to allow the gasket to slip and move out-of-position upon getting squeezed under compression.

Also, for any bolts that enter into water ports, use a non-hardening thread sealer.

Best bet, read the gasket mfgr's instructions... I wrote the Fel-Pro FIT forms for gasket installations.
