[Vwdiesel] OT- aluminum parts stuck

[Terry Briggs]

Had that happen with a mag light, I set the end in a jar with kroil in 
it for a few days and then tapped around the base for a few minutes to 
break the threads loose, it still took a good bit to get it to unscrew, 
but it came off. then just chase the threads to clean it out. Tape up 
any part that can leak and pour some coke in it and let it set over 
night, rinse with lots of hot water to get the coke out. Your mileage 
may vary, but it worked for me.
