The Bolts from Hell...

Galvanic corrosion my friend..an excited car enthusiast with some new hardwares worst enemy!

I ended up having to cut the bolt heads out and drill the body of the bolt out and just replace the bolt. I had a buddy who had great success with driving the heck out of the car for awhile to heat the bolts up and then trying.

*** Nevermind - I see you already tried driving the car to heat the bolts.

Since the driving around I haven't turned on them. I'm going to WOT like crazy on the way back. Maybe I can get them to crack.

Since the car has been stock for three years and 11.5K miles, I'm willing to bet the stud and the surrounding metal have become fused... essentially a solid piece of metal. There's still a good coating of the homebrew penetrant so maybe I can just bury the throttle and get lucky... otherwise I'm gonna have to find some advice about how to drill out the bolts.

I've got a weekend free before more work comes my way, so I might just continually soak the bolts in penetrant. 24 hour working time!

Also, 24 Heures du Mans. Yes.

Use some real heat, driving around or using a lighter will never work. Acetylene torch, propane or butane torch to heat until glowing will do wonders for rusted nuts/bolts.

Same thing happened to me... I just cut the bolt heads off
