I have to agree w/ Vince-don't use the sealant. In years of wotking on cars, removing and installing components, the only reason for using any type of gasket sealant is to position the gasket when installing something, so that the gasket stays in place, or to remedy a problem with seating surface imperfections that don't allow just the gasket to complete the seal. You also can make the old gasket hard to remove and potentially not reusable by gluing it to one or the other surface. Sealant can also be used, in a pinch, to reinstall a component with an old broken or brittle gasket when you have no choice and need to make it work. I have had my FC tb off and on a few times and have not put any sealant on it-also, with all the components on the JRSC kit there is no sealant used or recommended during the install. It''s also important to properly torque all components upon install-too tight can destroy a gasket and/or break bolts while too loose can cause leaks and parts to fall off.
