      You should be able to see. Best to just put some rtv gasket maker in them.

      I can't get the leak to stop.

      The area is smooth, im torquing like supposed to, but it wont stop leaking. I am thinking putting a 1/4" bead around the coolant port and then set the intake on top.

      You think that would seal the leak or its a waste of time?

      Are you getting the area as dry and clean as possible ?

      Are you letting everything sit for 24 hours still dry for curing and then doing a light torque check afterward ?

      Yes I let it sit for 24 hours. But I read the instructions on the rtv. It says to put rtv on, then lightly torque it, after 24 hours then torque to full value. I torqued it to 18ft right away. Maybe that was my mistake?

      Well if the RTV says light toque and you didn't the first time try it the second time.

      When you torque it right down you squeeze out all but the very least amount of RTV. When lightly torqued there is more there to setup and cure

      I think you have a bad intake. Shouldn’t be this much problem. You sure all the gaskets were present?

      I ended up putting the old OEM one back on and bought new upper intake manifold gaskets and it sealed it right up. Learned lesson, no more messing around with Dorman products.
