I appreciate the workaround, however, zip ties will slip off because the tower is tapered slightly. A thin wire is a more robust idea but still requires something to offset the smooth tower taper. Either way, I fixed the problem of the elbow coming out already with the long bolt from the timing belt cover.
The new problem is the blow-by gases are getting out through the gap left by a loose fitting elbow being held in place by the bolt. Seems I can't win.
