I recently bought an 02 svt with a vortech supercharger on it. The return oil line for the supercharger leaks where it's tapped into the block. I bought a new fitting, 3/8's hex npt, to replace the old one. I got under the car today and the threads on the fitting in there are stripped. I can turn the fitting by hand but cannot get it to loosen or tighten. I know I can drop the oil pan and get it out but I'm trying to avoid that whole mess. Any ideas?
