I have soaked the valley pan and it seemed to look good. I was ready to install and noticed crap falling out of baffles underneath.
I decided to cut spotwelds.
I am glad I did.
I had a lot of crap inside as well as "steel Wool" in the baffle area. I removed as much of loose steel as I could and repacked it with #3 steel wool. Then spot welded it closed.Just thought i would pass along this info for anyone who may want to know what's inside!
