Flapping noise on acceleration ???

  1. #1
    finally got my car back running :> anyways there is now a noise that sounds very much like paper or plastic flapping at high speed when acclerating at high revs most noticeable in 2nd gear....... is their anything i might of done wrong to cause this never noticed it before.

    Put oil sump back on. _ - 2 rounded nuts.
    Put down pipe - manifold back on. - 1 nut is a bit shagged dont think it is super tight.
    Put cam covers back on. -1 bolt which was always like that.

    re sealed oil sump and resealed where manifold meets down pipe. The noise seems to be coming from Drivers sides and sounds lowish.

    thanks.
