Title: S.O.S.
Post by: SHREDDER on January 03, 2006, 01:13:56 AM: I ran into a bit of trouble working on my 98 B6 the other day. I got an aftermarket ignition advancer and when trying to remove the frozen OEM part I ended up stripping the bolt holding it in. I just bought a bolt extractor kit from Home Depot so I think I will try that. I was also thinking of using a propane torch to heat it up and maybe it will loosen up a bit. Does anyone have any suggestions?

I like to soak the broken bolt in penetrating oil and when drilling for the extractor, us a reverse twist drill bit and drill the hole with the motor in reverse. Sometimes, this will be enough to remove the bolt. If not, then use the extractor.

Just be VERY CAREFUL when drilling the hole in the bolt, if you break out of the bolt material, you'll be in the crankshaft - and you don't want to screw that up!

You got some metric tools don't you Shredder? :stickpoke:

Post by: SHREDDER on January 03, 2006, 07:15:31 PM: Yes I have metric tools. It's a 7mm allen head that stripped. The entire bolt is still intact. A mechanic friend of mine just told me not to use the propane torch to heat it up cause of the aluminum parts in there. So I am going to try the extractor first and if that doesn't work then drill it out. He said if I put the transmission into gear then the crankshaft will not turn while I am working on it. Does that sound right?
