Nothing is ever easy on these cars...
My heat exhangers got some oil in them from the bad oil cooler seals, so I decided to pull them for a good cleaning. One exhaust nut was really difficult to remove. Once I finally got it off, I saw that the threads were galled. Ordered some new exhaust studs. Went to work removing the old one after researching 914 world. Heated stud boss with MAP torch & sprayed a bunch of PB blaster. Welded a nut on the end...nut kept breaking loose without budging the stud, removing small portions off the top of the stud during the six attempts. Then welded a bar to the remainder of the stud and used an adjustable wrench for leverage. Heat & PB Blaster, working it a little at a time, back & forth. It finally broke free. Reheat & apply more PB. On about the 5th cycle, the stud broke off below the level of the head. Engine is in the car & I'd like to keep it that way. What are my best options for getting this thing out now...and installing a new stud? I've had horrible luck with EZ-outs on other applications. Thanks!        |
