    Default Lower Intake Manifold leak sealer?

    Does anyone know of a for sure additive that will seal a small leak? I've used Bar's Leak #1109 without success so far.

    The LIM was replaced a year ago and is now seeping around the silicone seal on the front edge.

    After re-sealing, I may flush and refill with a Dex cool alternative just to eliminate that as a possible problem. From what I've read, Dex cool has an adverse affect on silicone sealants. Although what I used was Prestone's Dex-cool. Any difference?

    Thanks for your experienced input.
