bump?? ideas??

Well the 3.8's were pushrod engines, so that's always a possibility. That or an exhaust leak at one of the manifolds.

Dad had a 96 3.8 and ended up with a broken rocker base. He ended up pulling and replacing the heads...

That problem was fixed after november of 96

These motors have somewhat noisy lifters in many of these engines. The tappets in my 200K mile 3.3 in my beater Intrepid clatter and have for as long as I have owned it. Other than that, it is a great running engine and very strong.

In extreme cases, rockers have failed a few times in the 3.3/3.8 engine family. Remember, these are roller lifters, which can be somwhat vocal.

We had a rash of those when new that had loose exhaust manifold bolts, right around that year. If its bottom end and its been maintained, I'd be surprised. Thats been a great engine, and has a reputation of taking abuse. I'd look around the manifolds for some black soot first.
