[Retro]

Heheh, once I took my old jetta in because at a certain rpm it would sound funky, and noticeable to passengers in the mornings (so the mechanic can't say they heard nothing!). Well, I was hopping it was nothing serious and instead I ended up waiting for them to re-build my engine.. in the end, after replacing almost everything they figured out it was a valve that opened up in the intake manifold.
