I want to bypass or block off the Throttlebody/Idle speed controller coolant lines on my 87 Toyota Supra Turbo but do you guys think that I should put rubber caps on the intake manifold and the metal coolant pipe return line(to prevent the flow of coolant)or should I run a rubber coolant hose from the intake manifold to the metal coolant pipe return line(so that I still have circulation of the coolant)? Thanks:biglaugh:.
