It's been fairly trouble free driving with my 02 TB. I have almost 176K miles on it. I noticed a couple days ago that it's developed a weird noise that sounds like rocks being shaken in a plastic cup. It only makes the noise at just below 2K rpm, and not even all the time, but it's very noticeable when does happen. Other than that, the engine is runs quiet and nice and smooth. Valve issue?
Anyone have an idea?
