Sheared Brass Manifold Screws

["content22207" <brobertson@xxxx>]

Re: past posts from owners with snapped off manifold screws:

According to just received Volvo 260 CI manual:

B28F used "shear-head" balancing screws. Are designed to snap off
easily when snugged down.

Idle inlet screw never shear-head.

Since all three ports are identical: if owner with sheared off screws
wants to use them, can substitute two inlet screws. Should be easy to
remove sheared threads since over-torquing was not cause.
