The results were a bit more dramatic than I thought. It's the 2.4 liter.
I was expecting lots of white smoke, not SOOT. You can see the grass was already black from the initial seafoam introduction. Some actual black pieces came out.
I seafoamed my current 03 3.4 liter and there was not an ounce of smoke.
Safe to say that the cat is screwed, or at least its life has been shortened.
I have no idea how to embed this video...
