tech: ac compressor bracket stud

[wgirardot]

Guys, I have an '82 SC. There are 2 studs that are in the cam tower pointing up (by the right side of the fan shroud). One of the ac compressor brackets is secured to these studs with nuts. One of the studs is sheared off flush. If I drill this out, am I at risk of metal shavings getting into the area behind the valve cover? Does this stud go all the way through into the internals of the engine? I've pretty much butchered this up already trying to get this stud to turn.

please advise, any advice/methods welcome.

I am pointing at the sheared stud. The 2nd stud is in the backround straight back. These studs secure a bracket for the compressor in addition to the main supporting bracket. Please advise if: 1). I need this attachment point 2). If I drill it out, will I
introduce metal shavings into valve area? As far as I know, I've been "running" this way for a long time.

again suggestions/comments welcome

You would have to drill pretty deep to go into the rocker area, but you could do it. When I did my rebuild most of those were sheared off. It only took enough drilling to get an easy out in and it came right out.

Oh and, yes I think you need that attachment. Without that bracket the compressor doesn't align well to the front pulley.

I am pretty sure I am beyond getting an "easy out" set up properly. I haven't blown through yet. Any suggestions?

Don't worry about the drilling even if you drilled more than 1.5". It won't go any further because you'll be hitting the cylinder head 8 mm stud. All you need is a threaded hole of 1/2" to 3/4". The cavity (threaded hole) is just about 3/4" deep. Your concern about producing metal shavings going inside the engine will not happen (valve covers installed) even if you try to do it!!!!!!

Get an 'EZ-OUT' set (drill with reverse tap set), your working on a 6mm diameter bolt.
Drill, remove, vacuum and blow dry.
