  1. engine swap '06 into '04 ? (USA cars)

    Gen 2: 2000-2004
    I've got a rather odd '04 with a evil sounding knock (like the piston slap of the early 2.5's, but louder), toasted clutch, 95% sure toasted HG including oil/coolant mixing, and rust-welded/now-snapped exhaust manifold bolts. It's odd because there's 3-4 extra O2 sensors and there's no throttle...
