Lifter Tick, Manifold Leak, or Something Else?

Hey All! My 89 Lincoln Town car is making a ticking noise when driving it for the first 5 minutes or so after starting. I was thinking it’s a lifter tick or an exhaust manifold leak, but it only makes the tick when driving. It won’t make the noise when revving the engine in park. The ticking noise speeds up and slows down when the car speeds up and slows down, but doesn’t seem to have anything to do with the engine RPMs. It doesn’t seem like the brakes because it doesn’t change the noise at all when applying the brakes and the noise completely stops when the engine is warmed up.

Any other ideas what might be going on? Could it be a lifter tick or manifold leak? Thanks for your help!

If it related to the speed of the car, not the engine it would not be engine related. First simplest hope a stone or a nail etc. stuck in the tire.
