View Full Version : 351 Riser gasket question

06-23-2012, 12:39 PM
I just installed a new pair of risers and manifolds on my 93 S&S. After a few outings, they leak from the gaskets. Does any one out there have a tried and true installation procedure on sealing the risers to the manifolds? I used the correct gaskets, and Permatex #1. Ski Dim reccomends grey RTV. These are GLM replacements.
