Cold Rattle, hard to find

[TheV6Bird]

My 97 3.8 A4 vert has this annoying rattle. It is most pronounced on startup and cold idle, rattling on and off. When the car warms up, it almost totally goes away. I can't totally pinpoint it either....it isn't the cat heat shield, the fuel tank heat shield, the X-brace (for verts).

Could it by the Y-pipe? Is that a common 3.8 problem? Where does the Y-pipe usually vibrate from?

I got underneath my car today and since it is 90* out I guess whatever is rattling has expanded and doesn't rattle right now :rolleyes: I took some pictures though. I found that where the S-pipe connects to the I-pipe has water around the area and is leaking from the combustion water inside of the exhaust. Is this normal?

Re: Cold Rattle, hard to find

there shoulnt be water in the combustion do you live where its very humid and a exhaust leak will rattle

Yeah it is actually very humid in my area right about now. I'm gonna get under the car again to see if I can still find anything
