There are many links as to how to set up the manifold test with a "schrader valve", pressure gage and a bicycle pump.

Once the results of BOTH tests are negative then time to test the block.

Ok, but do I still need to if the manifold holds no pressure and I could hear air escaping back into exhaust?
