Intake oil leak and 360's

Where are they leaking?

If it's the ends, I have a little tip when not using the gaskets. I never use the gaskets, only RTV.

The top shelfon the block where the intake seals is pretty big/wide. If you covered the entire shelf, you're wasting RTV. Clean the block surface. Set the intake on the block/heads. Use a sharpie and draw a line referencing the edge of the intake. Look at the bottom of the intake for the width of the sealing surface. Lay a tall bead of silicone maybe 1/16 inside the drawn line and run it up, connecting with your intake manifold gasket.

That should give you a nice rtv surface to seal the ends of your intake.

Use good RTV like Right Stuff or RTV Black.
