When to tighten intake manifold bolts on 98 Chevy 350 vortex? At what torque must the Intake Manifold Bolts be tightened to on a 98 Chevy 350 Vortex Two years post replacement the manifold seems to be leaking again? What are the gaskets on the intake manifold made of? They can be made of paper, rubber, metal, and sometimes a combination of the three. The intake manifold gaskets are responsible for sealing the intake manifold against the cylinder head(s). Apart from sealing engine vacuum, certain designs will also seal engine coolant. Can a bad intake manifold cause a coolant leak?...
