This is a very common problem on the S197 models, but easily prevented. Clean the cowl drains regularly. This is probably the #1 cause of water entering the cabin. And it can be an expensive one.

Also, (I think it was the very first reply), someone mentioned the rear timing chain, or timing chain noise in general. Although I have not personally experienced this in person, One thing that would probably be a good idea would be to replace the 2 timing chain tensioners. They are basically little spring loaded pistons that press against the timing chains (front and rear), and keep the chains from slaping and destroying the plastic chain guides. They are easily accessable without opening the engine, takes about 10 minutes to do the job. Of course this depends on milage on the engine, but I think Ford recommends replacing them every 75k miles. I replaced mine (because I thought they were failing but they weren't) at 105k. The pair cost about $150 bucks, but give me piece of mine when I pulled the old ones out and felt the difference in spring tension.
There are all kinds of theads on this, cowl leaks, and the thermostat housing failure if you need more confirmation. Hope this helps.

Check out this video, it explains it all. There is also a drain on the drivers side you need to check.

Also notice the gromets where the cowl vent (covers) mount, they too deteriorate with wear and time. They too will cause leaks if not addressed.
