Staffan,

below the line that counts.

maybe your way works because of the nearly double as high expansion coefficient of alloy against steel and because of heating up the stud means heating the alloy area at the same time.

I weld nuts on, when the glow has transferred to the stud, I start to remove. Remember, the Alu expands too. Also you would tend to harden the stud, not weaken it. It can still snap off though, just due to torsion.
But heat is the best way. Welding the nut on gives you something to grab, and heats the fastener, which heats the surrounding area, causing it to expand, and loosen the grip on the stud. In cases of severe corosion, it may snap off flush,I then pilot drill the stud, then drill it out to 6MM, using a left hand tap extract the remnants.

jayster - nice smiley face on your turbo drain resevoir...

BTW, looks like your a DIY kinda guy as i am. maybe you've been to my store.


i'll keep an eye out for a blue turbo (i had a '79 930 i painted Cobalt blue a few years back
