While I was replacing the oil pan the o2 sensor and egr tube broke (at the pipe). The o2 stripped, so I'm stuck drilling and tapping...does anyone know the thread size. Also, does anyone know the max temp at the exhaust end of the egr tube? I'm looking to use steelaloy to put the tube on, and its melt temp is just over 500F.

Thanks

Pat

 

Also, any one know where I can get the exhaust from the heads to the cat, should I decide to just replace this section
