Any ideas on Loud ticking noise from passenger side, engine compartment.

What is your question?

Fixed exhaust leaks in manifold pipes, but ticking is loud and worse under car. Very pronounced at idle. Revving engine seems to smooth the noise even with slight increase to rpms. Acceleration is strong but the cabin noise is more like a big truck has that feel like its all engine shaking down the car. Could a cracked exhaust manifold be the issue?
