The top weld on my header pipe has an intense little blue patch about 1/4" wide going along the weld for about 1". It's on the under side of the pipe, no other changes to fuel or timing, just bolted on new header pipe on the right side. Pipe that came off was a nice straw/neutral colour, its not like when pipes blue, rest of the pipe is normal colour as expected, it's just a small little area, any ideas what could be causing heat just in this one spot??
