Leaking anti-freeze and oil

Good morning.

Check the hoses that go to the intake for any damage or loose clamps. If you can, pressure test the cooling system to find the leak. You can rent a tester at a parts store if you do not have a tester.

As far as the oil leak, it could be valve cover gaskets seeping onto the manifold. If all these checks are good, it is a very good chance the intake manifold itself is leaking.
